  • The Outdoor Problem Inside Your Data Center Energy Bill

    The Outdoor Problem Inside Your Data Center Energy Bill

    Data center executives are accustomed to tracking Power Usage Effectiveness (PUE) to the second decimal place. They invest in advanced cooling architectures, optimize airflow management, and benchmark against the best hyperscalers in the industry. Yet one of the most consistent drags on cooling efficiency sits entirely outside the building—and outside most efficiency roadmaps. The physical condition and thermal environment of the outdoor HVAC equipment that actually handles the heat rejection.

    Cooling already represents a significant share of total data center energy consumption. According to McKinsey’s 2024 research, cooling systems account for approximately 40% of a typical data center’s total facility energy use. A separate analysis by Pew Research Center found that cooling’s share ranges from about 7% at the most efficient hyperscale facilities to over 30% at less efficient enterprise operations. Much of what separates those two ends of the spectrum comes down to how well the physical cooling infrastructure is maintained and protected.

    Two specific outdoor degradation factors — solar-driven thermal loading and coil fouling from corrosion and environmental debris — are responsible for a material portion of excess cooling energy consumption and are largely preventable. Understanding and addressing them proactively is one of the most accessible levers for data center operators looking to improve PUE without major capital reinvestment.

    How the Outdoor Environment Undermines Data Center Cooling Efficiency

    Data center cooling systems — whether centralized chilled-air systems, chilled-water loops, or computer room air conditioners (CRACs) — all share a common dependency. They must reject heat to the outdoor environment. That exchange occurs through rooftop-mounted condensing units, cooling towers, and air handlers. The performance of this equipment is directly affected by the conditions in which they operate.

    Solar thermal loading. Rooftop HVAC cabinets and condensing units in direct sunlight regularly reach exterior surface temperatures of 180°F or higher. That temperature is even on days when ambient air temperatures are moderate. The thermal energy transfers into the cabinet interior, raising the temperature of the environment in which the compressor and refrigerant circuit operate. The result is longer run cycles, higher energy draw per ton of cooling delivered, and accelerated mechanical wear. HVAC units are rated under ARI laboratory conditions that do not replicate the real-world rooftop heat load. This means most facilities are operating equipment that performs below its rated efficiency from day one of outdoor deployment.

    Coil fouling and corrosion. The heat exchanger coil is the core of any HVAC unit’s efficiency. Over time, exposure to airborne contaminants, humidity, industrial pollutants, and salt or chemical particulates corrodes the coil’s fin-and-tube structure and degrades the fin-to-tube bond that enables efficient heat transfer. Biological fouling adds another layer of blockage. The coil continues to function, but at progressively lower efficiency with more kilowatts consumed per ton of cooling, higher compressor strain, and an accelerating path toward failure. In data center environments, where cooling demand is continuous and mission-critical, this degradation directly erodes PUE.

    The Scale of the Problem at a Typical Data Center

    The Congressional Research Service has noted that roughly half or more of a data center’s electric power demand stems directly from IT equipment operation. The remainder is going to cooling. For a 100-megawatt facility — a scale increasingly common as AI-driven workloads drive capacity expansion — that means tens of megawatts of continuous cooling load operating around the clock, every day of the year.

    Even a modest improvement in cooling system efficiency compounds significantly at that scale. A 10% reduction in cooling energy consumption on a 40MW cooling load represents 4MW of recovered capacity. That is enough to power thousands of additional servers, defer infrastructure expansion, or directly reduce utility expenditure. The industry average PUE remains approximately 1.56, compared with a hyperscale benchmark closer to 1.2, according to the Uptime Institute’s 2024 survey. Closing that gap requires addressing every layer of inefficiency, including the ones that originate outdoors.

    ThermalBlock by Coat Zone®: Eliminating Solar Heat Load at the Source

    ThermalBlock by Coat Zone® is a high-performance radiant barrier coating applied directly to the exterior surfaces of rooftop HVAC cabinets, condensing units, air handlers, and exposed ductwork. It addresses solar thermal loading before it becomes a compressor burden.

    Independent testing confirms that ThermalBlock by Coat Zone® blocks up to 93% of solar heat, reducing treated surface temperatures to within 10°F of ambient air even under peak summer solar conditions. It reflects 89% of visible light (ASTM C1549) and rejects 87% of heat gain from external sources (ASTM C1371), achieving a Solar Reflective Index of 108 across varying wind conditions. This is a score that holds up in real-world deployment, not just laboratory baselines. The thermal conductivity of treated surfaces is reduced by approximately 13% (K-Value), while thermal resistance increases by approximately 20% (R-Value).

    For data center operators, the operational impact is direct:

    • Reduced compressor run time during peak ambient temperature hours
    • Lower kWh consumed per ton of cooling delivered
    • Extended equipment lifespan — ThermalBlock by Coat Zone® increases HVAC system longevity by up to 30%
    • ROI achievable within 12 to 36 months on minimal capital investment

    ThermalBlock by Coat Zone® is applied on-site to both new and existing equipment, with a water-based, low-VOC formulation and a 10-year warranty. This makes it a low-disruption, low-risk upgrade compatible with active operational environments.

    CoilSafe®: Protecting the Efficiency Core of Your Cooling System

    CoilSafe® is an ultra-thin inorganic coating — just 8 to 10 microns thick, approximately 40 times thinner than standard epoxy coil coatings — applied to HVAC heat exchanger coils to prevent corrosion, restore heat transfer performance, and inhibit biological fouling. Where standard coatings add bulk and can impede airflow, CoilSafe® wicks into the coil’s structure at the molecular level. It retightens the fin-to-tube bond and forms a glass-like inorganic surface that resists moisture, oils, mold, and environmental debris without restricting heat exchange.

    The result is a measured 10% improvement in HVAC efficiency (kW/ton), corrosion protection validated through 6,000 hours of salt fog testing (ASTM B117) and 25,000 hours of atmospheric corrosion exposure (ASTM G50), and zero fungal growth in ASTM G21 testing. Because it forms a permanent covalent bond, CoilSafe® will not flake, peel, or degrade — even under sustained environmental stress.

    For data center cooling systems operating continuously in environments ranging from coastal humidity to urban industrial air, this level of coil protection directly translates to sustained efficiency over the full service life of the equipment. Rather than the gradual performance erosion that typically goes unmeasured until a replacement event forces the issue.

    Proven at Scale: The AT&T Galveston Case

    The durability and performance of CoilSafe® is not theoretical. AT&T faced a severe coil corrosion problem at its Galveston Island facility. This area is one of the most corrosive coastal environments in the United States. Constant Gulf of Mexico salt spray was reducing rooftop HVAC coil lifespan to just three to four years. After applying CoilSafe® to new rooftop units at installation, a follow-up inspection nearly eight years later found the coils remained pliable, corrosion-free, and fully functional. The application also delivered a 15% reduction in HVAC energy consumption. This deferred replacement capital and materially improved operating efficiency at a facility where HVAC reliability is non-negotiable.

    The AT&T result is instructive for data center operators. In environments with elevated corrosion risk — coastal proximity, industrial air quality, high humidity cycling — the degradation timeline for unprotected coils is measurable in years, not decades. CoilSafe® interrupts that cycle at the point of installation.

    A Low-Cost Lever for a High-Cost Problem

    Data center efficiency investments tend to focus on IT hardware, power distribution architecture, and advanced cooling system design. All of which involve significant capital commitment and planning cycles. ThermalBlock by Coat Zone® and CoilSafe® represent a different category of investment. That is, protective coatings applied to existing equipment that recover efficiency being lost to entirely preventable physical degradation.

    The combination of reduced solar heat loading and restored coil performance addresses the two primary outdoor-environment contributors to cooling inefficiency, with ROI timelines that compare favorably to virtually any alternative efficiency measure under consideration. For data center executives focused on PUE improvement, sustainability commitments, and operational cost management, these coatings belong in the efficiency conversation.

  • Your HVAC Coils Are Costing You More Than You Think

    Your HVAC Coils Are Costing You More Than You Think

    Here’s something most business owners don’t realize: your HVAC system didn’t start losing efficiency the day it broke down. It started losing efficiency the day it was installed. Slowly, quietly, and in a way that shows up on your utility bill long before it shows up as a service call.

    The culprit is usually the coil.

    What Happens to HVAC Coils Over Time

    The heat exchanger coil is the part of your HVAC system that actually does the heating and cooling. It’s a tight network of fins and copper tubing. When it’s working properly, heat transfers efficiently between the refrigerant and the air moving through your building.

    But over time, a few things happen. Corrosion sets in. Mold and debris accumulate in the fins. The bond between the fin and the copper tube, which is critical for heat transfer, begins to loosen. The coil is still technically “working,” but it’s working harder to do less. Your system runs longer cycles, pulls more kilowatts, and wears out faster.

    HVAC systems already account for 50% or more of energy use in most commercial buildings. A degraded coil pushes that number higher every month.

    So What Does CoilSafe® Actually Do?

    CoilSafe® is a thin-film inorganic coating applied directly to your HVAC coil, either in the field or at a service shop. At just 8 to 10 microns thick (about 40 times thinner than a standard epoxy coating), it doesn’t block airflow or reduce heat transfer. It does the opposite.

    The coating wicks into the coil’s structure at a molecular level, retightening the fin-to-tube bond and restoring the heat transfer that corrosion and age have degraded. It also forms a glass-like surface. This surface resists mold, moisture, bacteria, and the kind of environmental gunk that clogs fins and drives up maintenance costs.

    The result is a measurable 10% improvement in HVAC efficiency, less energy consumed per hour of operation, and a unit that performs closer to what it did the day it left the factory.

    What That Means for Your Bottom Line

    For business owners, the math is pretty straightforward. CoilSafe® is a one-time application on existing equipment. You avoid replacement, avoid major downtime, and avoid significant capital outlay. Most clients see a return on investment within 12 to 36 months through lower utility bills and reduced maintenance frequency.

    It also extends equipment life considerably. Corrosion is one of the primary reasons HVAC units get replaced before their time. Protect the coil, and you protect the investment you’ve already made in your equipment.

    And because CoilSafe® is antimicrobial and supports better indoor air quality, there’s a secondary benefit for your team and your customers: cleaner air circulating through a cleaner system.

    TL;DR

    If your HVAC system is more than a few years old and you haven’t thought about the coil, you’re probably leaving money on the table. Money in energy costs, in maintenance calls, and in equipment life. CoilSafe® is a simple, proven fix for a problem most people don’t know they have.

  • Energy Intelligence Starts with Your HVAC System

    Energy Intelligence Starts with Your HVAC System

    Facility and plant managers are under mounting pressure to reduce operating costs and demonstrate progress toward sustainability. All while keeping equipment running reliably, often with the same budgets and headcounts as before. A recent article in Automation World highlighted a compelling shift in how leading manufacturers are approaching this challenge. By treating energy as a measurable, controllable production input rather than a fixed line item on the monthly utility bill.

    That concept, energy intelligence, is reshaping plant operations. Real-time monitoring platforms, demand management tools, and predictive maintenance strategies are allowing facilities to see exactly where energy is going and why. But for all the sophistication of these digital systems, there remains a physical blind spot that erodes efficiency before any sensor can even measure it. This blind spot is the condition and performance of your HVAC equipment.

    At Coat Zone®, we believe true energy intelligence requires addressing the hardware layer and not just the data layer. And HVAC coatings are one of the most cost-effective, high-impact tools available to facility managers looking to close that gap.

    The Missing Variable in Your Energy Intelligence Strategy

    Modern energy monitoring platforms can tell you how many kilowatt-hours your facility consumed in the last hour. What they often cannot tell you is how much of that consumption is driven by degraded equipment performance. This includes coils caked with corrosion and compressors working under solar heat loads that were never factored into the original system design.

    HVAC systems are among the largest energy consumers in commercial and industrial buildings. They frequently account for 50% or more of total energy use. In rooftop-mounted configurations, units are exposed to conditions that lab testing rarely replicates. Direct solar exposure can drive exterior cabinet temperatures to 180°F on an otherwise mild day. This then forces compressors and fans to run longer and harder than their rated specs were designed to handle. The result is increased runtime, higher kWh consumption, accelerated wear, and a shorter equipment lifespan.

    This degradation occurs gradually, making it easy to miss in standard energy monitoring dashboards. But the kilowatts are being consumed nonetheless, and they are costing you money every hour of every operating day.

    ThermalBlock™: Reducing Solar Heat Load at the Source

    Coat Zone®’s ThermalBlock™ is a high-performance radiant barrier coating applied directly to the exterior cabinets of rooftop HVAC units, exposed ductwork, and air handlers. Its purpose is straightforward: stop solar heat from entering the system before it ever becomes a thermal burden.

    Independent lab testing confirms that ThermalBlock™ blocks up to 93% of solar heat. By blocking the heat, it reduces surface temperatures to within 10°F of ambient air even in peak summer conditions. The coating reflects 89% of visible light (ASTM C1549) and rejects 87% of heat gain from external sources (ASTM C1371), with a Solar Reflective Index of 108. These results indicate exceptional performance across varying wind and weather conditions.

    For facility managers focused on energy intelligence, the operational implications are significant:

    • Reduced HVAC run time, particularly during peak demand periods when utility pricing is highest
    • Lower kWh consumption directly improves energy-intensity metrics such as energy per unit produced
    • ThermalBlock™ has been shown to increase HVAC system longevity by up to 30%
    • ROI is typically achieved within 12 to 36 months on minimal capital investment

    ThermalBlock™ can be applied on-site to both new and existing systems. Therefore, it is a low-disruption upgrade that complements rather than replaces ongoing energy monitoring initiatives.

    CoilSafe®: Restoring Efficiency Where It Is Lost Most

    If ThermalBlock™ addresses the external thermal environment, CoilSafe® addresses the internal performance core of your HVAC system: the heat exchanger coil.

    Over time, HVAC coils can suffer from corrosion, biological fouling, and the gradual degradation of the fin-to-tube bond, a critical interface where heat transfer occurs. Each of these factors reduces system efficiency and drives up energy consumption in ways that are often invisible until a major failure occurs. CoilSafe® is an ultra-thin inorganic coating, just 8 to 10 microns thick, approximately 40 times thinner than standard organic coatings. The coating wicks into the coil’s structure and bonds at the molecular level, restoring the fin-to-tube connection and improving energy transfer performance.

    The practical results include a 10% improvement in HVAC efficiency, as measured in kW/ton. The corrosion protection was validated through 6,000 hours of salt fog testing (ASTM B117) and 25,000 hours of atmospheric corrosion testing (ASTM G50). The coating also creates a glass-like antimicrobial surface that resists mold, mildew, and environmental debris. Additionally, CoilSafe® contributes to healthier indoor air quality, which is increasingly relevant to both occupant health and regulatory compliance.

    For energy intelligence programs, CoilSafe® addresses a root cause of anomalous energy consumption. When energy monitoring data reveals that a particular unit is consuming more kWh per ton than expected, corroded or fouled coils are frequently the culprit. CoilSafe® provides a preventive and restorative solution. It helps your equipment continue to perform closer to its original factory specifications throughout its service life.

    Amplifying the Value of On-Site Renewable Energy

    The Automation World article noted an important dynamic for facilities investing in solar, wind, or cogeneration. That dynamic is that the return on investment is not limited to kilowatt-hours generated. It also includes avoided demand charges and reduced peak pricing exposure. If a facility experiences midday demand spikes, on-site solar can shave those peaks but only if HVAC systems are not simultaneously driving consumption higher than necessary.

    This is where HVAC coatings become a force multiplier for renewable energy investments. By reducing HVAC run time and lowering overall system energy draw, particularly during peak solar hours, ThermalBlock™ and CoilSafe® increase the proportion of on-site generation that can be applied to other facility loads or fed back to the grid. The net effect is a higher utilization rate for your renewable assets and a stronger ROI case for future clean energy investments.

    Additionally, reduced energy consumption directly lowers carbon emissions per unit produced. This is a metric that sustainability and ESG reporting frameworks increasingly require. HVAC coatings contribute measurably to that number without requiring major capital expenditure or operational disruption.

    Building a Complete Energy Intelligence Stack

    Energy intelligence, at its most effective, operates at every layer of a facility’s infrastructure, from the software platforms that monitor and optimize energy flows in real time to the physical condition of the equipment producing and consuming that energy. Digital monitoring tools provide visibility. Coatings protect the hardware that makes the data meaningful.

    Facility and plant managers who invest in both layers, modern monitoring alongside proactive equipment protection, position their operations for lower utility costs, longer asset lifecycles, stronger sustainability performance, and greater resilience against energy price volatility.

    ThermalBlock™ and CoilSafe® from Coat Zone® are designed to be exactly that kind of foundational investment: proven, low-disruption, and demonstrably effective. Plus, with ROI timelines that make the business case straightforward.

    If your facility is building out an energy intelligence strategy, we encourage you to evaluate what your HVAC equipment is costing you before any monitoring tool can see it. Contact Coat Zone® to learn more about how our coatings integrate with your operational efficiency goals.

  • The Future of Smart Buildings is Going Beyond Predictive

    The Future of Smart Buildings is Going Beyond Predictive

    The transition from reactive to predictive performance is the current gold standard in smart building management. But for facility managers looking to truly future-proof their assets, there is a third, even more critical layer: Preventive Protection.

    While predictive maintenance tells you when a part might fail, and preventative maintenance ensures you check it before it does, Coat Zone’s advanced coatings offer a solution that physically shields equipment from the stressors that cause failure in the first place.

    Here is how pairing these approaches, specifically for HVAC systems in smart buildings, can transform your operational efficiency and equipment lifespan.

    The Maintenance Trio for Smart Buildings

    To understand the full value, we must look at how these three strategies work in tandem:

    1. Predictive (The Brain): Uses IoT sensors and AI to monitor real-time data (like vibration or temperature spikes). It predicts failure before it happens, enabling “just-in-time” repairs.
    2. Preventative (The Schedule): Involves routine tasks such as filter changes and coil cleanings to keep the system running according to manufacturer specifications.
    3. Protective (The Shield): This is where Coat Zone comes in. By applying high-performance coatings, you reduce the underlying “wear and tear” that predictive sensors eventually pick up.

    Why HVAC Systems Need More Than Just Data

    HVAC units are often the largest energy consumers in a smart building and the most susceptible to environmental degradation. Even with the best predictive sensors, a unit exposed to salt air, high UV, or corrosive pollutants will inevitably lose efficiency.

    1. Expanding Equipment Lifespan by 50%+

    Predictive maintenance in smart buildings can catch a failing motor, but it can’t stop a condenser coil from corroding. Coat Zone’s CoilSafe® and CoilSafe Plus® create a permanent, covalent bond at the molecular level. Unlike thick traditional coatings that can trap heat, CoilSafe is only 8-10 microns thick, making it thinner than standard options.

    This thinness allows it to bridge the microscopic gaps between the fin and the tube, restoring thermal connectivity and protecting the metal from “pitting” that can lead to refrigerant leaks. By preventing the root cause of decay, you can effectively double the useful life of the unit.

    2. Reducing Energy Usage (The 15–30% Difference)

    A predictive system might alert you that your HVAC is drawing more power than usual. Usually, this is because the unit is struggling to reject heat due to dirty or corroded coils.

    By pairing predictive data with Coat Zone’s ThermalBlock™ exterior cabinet coating, you attack energy waste from two sides:

    • Internal Efficiency: CoilSafe keeps coils “factory clean,” preventing the buildup of biofilm and scale that forces the compressor to work harder.
    • External Shielding: ThermalBlock reflects up to 95% of solar heat. This keeps the cabinet temperature within a few degrees of the ambient air, significantly reducing the “heat load” the system has to overcome before it even starts cooling the building.

    The Coat Zone Advantage for Smart Buildings

    The beauty of incorporating Coat Zone into your maintenance plan is that it simplifies everything else.

    • Easier Cleaning: The glass-like surface of CoilSafe repels debris. Instead of harsh chemical washes that can damage fins, a simple rinse with water is often all that’s required.
    • Reduced “Red Flags”: Because the unit stays cooler and cleaner, your predictive maintenance software will trigger fewer alerts, reducing labor costs and emergency “truck rolls.”
    • Rapid ROI: Most facilities see a return on investment within 12 to 36 months through energy savings alone, not even accounting for the deferred capital expense of a $100,000+ unit replacement.

    Moving Toward 2026 and Beyond

    As we move into an era where “intelligent buildings” are the norm, the goal isn’t just to respond faster to problems; it’s to ensure those problems never manifest. By combining the data-driven insights of predictive maintenance with the physical resilience of Coat Zone coatings, you aren’t just managing a building; you’re preserving an investment.

  • Navigating Energy and Environmental Challenges in Data Center Site Selection

    Navigating Energy and Environmental Challenges in Data Center Site Selection

    In this digital world, data centers are the unseen engines that power everything from social media to scientific research. However, behind every click and every downloaded file lies a massive physical infrastructure. Data center site selection decisions have profound implications, particularly for energy consumption and environmental impact.

    The Energy-Hungry Giants

    Data centers are notorious for their voracious electricity consumption. They consume an estimated 1-2% of the world’s electricity, a figure projected to rise [1]. This energy is primarily used for two purposes: powering the IT equipment itself (servers, storage, networking) and, perhaps even more significantly, cooling it. Servers generate immense heat, and maintaining optimal operating temperatures is crucial for performance and longevity.

    When making a data center site selection, energy considerations are paramount:

    • Availability and Reliability: A consistent and reliable power supply is non-negotiable. Downtime caused by power outages can be catastrophic, resulting in massive financial losses and data disruption. Sites near robust power grids or with access to multiple substations are highly desirable.
    • Cost: Electricity costs are a major operational expense for data centers. Regions with lower electricity prices offer a significant competitive advantage.
    • Renewable Energy Potential: Increasingly, companies are committing to sustainability goals, making access to renewable energy sources (solar, wind, hydro) a key factor. Locating near a renewable energy plant or a grid with a high percentage of renewables can significantly reduce a data center’s carbon footprint.

    Environmental Footprint: Beyond Energy

    While energy consumption is the most obvious environmental concern, data centers have other impacts:

    • Water Usage: Many traditional cooling systems, especially evaporative cooling systems, consume large amounts of water. As water scarcity becomes a global issue, the availability and cost of water are critical considerations.
    • Carbon Emissions: Even with commitments to renewables, the construction and ongoing operation of data centers contribute to carbon emissions. Particularly if they rely on electricity from fossil fuels.
    • Land Use: Data centers require a significant amount of land, both for the facility itself and for associated infrastructure such as substations. This can impact local ecosystems and agricultural land.
    • E-waste: The continuous upgrade cycle of IT equipment generates substantial electronic waste that must be responsibly managed.

    Strategic Site Selection: Mitigating Impact

    To address these challenges, data center operators look for sites that offer a balance of economic and environmental advantages:

    • Cool Climates: Regions with naturally cool ambient temperatures reduce the need for mechanical cooling, lowering energy consumption and operational costs. Places like the Nordics, Canada, and specific parts of the US offer these benefits.
    • Proximity to Renewable Energy: Sites adjacent to hydroelectric dams, wind farms, or large solar installations can offer direct access to green energy at lower cost.
    • Access to Sustainable Water Sources: For facilities using water-based cooling, proximity to sustainable water sources is crucial. As is the implementation of water-efficient cooling technologies.
    • “Waste” Heat Utilization: Innovative projects are exploring ways to capture and reuse the heat generated by data centers for district heating schemes or agricultural purposes, turning a waste product into a valuable resource.

    How Coat Zone’s Product Suite Can Make a Difference

    Regardless of where a data center is located, the internal and external thermal loads remain a constant challenge. This is where Coat Zone’s specialized product line provides a decisive advantage, offering a “dual approach” to thermal management that protects equipment while drastically reducing the environmental footprint.

    1. CoilSafe®: Restoring HVAC Efficiency

    The massive HVAC systems required to cool data centers often lose efficiency over time due to corrosion and debris. CoilSafe® is a thin-film inorganic coating (only 8-10 microns thick) designed to restore and protect these vital heat exchanger coils.

    • Energy Reduction: By retightening the bond between the fin and the tubing, CoilSafe improves energy transfer, helping units run closer to their original factory efficiency and immediately reducing kilowatt usage.
    • Extended Equipment Life: It prevents corrosion from shortening the life of expensive cooling infrastructure, ensuring a higher ROI and reducing the need for premature equipment replacement.

    2. CoilSafe Plus®: Advanced Microbial Protection

    In data centers where high-moisture environments or high-traffic areas can lead to biological fouling, CoilSafe Plus® adds an extra layer of defense.

    • Bacteriostatic Defense: Incorporating silver-ion technology, it achieves a 99.5% reduction in bacteria and prevents mold and mildew growth. This keeps evaporator coils clean, ensuring that airflow and heat transfer are never compromised by organic buildup.
    • Environmental Resilience: It is designed to withstand 6,000+ hours of salt-fog testing, making it ideal for data centers in coastal regions or harsh industrial environments.

    3. ThermalBlock™: The Solar Shield

    Data centers often house equipment in rooftop-mounted units or in exposed ductwork, both of which are subject to extreme solar heat. ThermalBlock™ acts as a high-performance radiant barrier for the exterior of the HVAC cabinets.

    • Blocking Solar Gain: ThermalBlock™ blocks up to 93% of solar heat, reflecting radiation before it can soak into the unit. This keeps the interior cabinet temperatures significantly cooler, within 10°F of the ambient air temperature, even during peak summer.
    • Reducing Run-Time: By shielding the system from solar load, ThermalBlock™ reduces the overall runtime of HVAC units, lowering energy consumption and reducing mechanical strain that leads to repairs.

    Efficiency From the Inside Out

    By combining these technologies, Coat Zone empowers data centers to be more thermally efficient at every level.

    • Water Conservation: By maximizing the efficiency of the cooling cycle through CoilSafe, the demand for evaporative cooling is reduced, directly saving thousands of gallons of water.
    • Density & Performance: Improved thermal management allows operators to maximize rack density without overtaxing the existing cooling infrastructure.

    In essence, Coat Zone enables data center site selection to mitigate environmental impact by doing more with less, using less electricity and water, and getting more years of use from their equipment.

    The Future is Efficient

    The ongoing growth of digital services demands a corresponding evolution in how we build and operate data centers. By strategically selecting sites aligned with environmental goals and integrating cutting-edge technologies like Coat Zone, we can ensure the digital world continues to thrive without compromising the health of our planet. The future of data centers is not just about raw power, but about intelligent, sustainable power.
