  • Securing the AI Boom in the Americas

    Securing the AI Boom in the Americas

    The data center market in the Americas is no longer just growing. The AI boom is surging at a pace that is fundamentally altering the global digital landscape. According to recent industry analysis from Business Facilities, the Americas have solidified their lead as global data center capacity explodes. This lead is largely driven by the unrelenting demand for Artificial Intelligence (AI) and high-performance computing (HPC).

    As of 2025, the U.S. remains the epicenter of this expansion. Northern Virginia, the world’s largest data center market, saw under-construction capacity jump by 80% in the first half of 2025 alone (CBRE). However, this rapid growth brings two critical challenges that threaten to stall the AI revolution. Unprecedented energy demand and the silent degradation of cooling infrastructure.

    At Coat Zone, we believe that the key to sustaining the AI boom isn’t just about building more. It’s about protecting and optimizing what we already have.

    The Energy Paradox: AI’s Massive Cooling Appetite

    Data centers are among the most energy-intensive facilities on Earth. In 2024, data centers consumed approximately 183 terawatt-hours (TWh) in the U.S. alone—roughly 4% of the country’s total electricity (Pew Research). By 2030, this demand is projected to grow by 133% to 426 TWh.

    The “energy hog” in the room is cooling.

    • The Cooling Tax: Cooling systems are the second-largest energy consumer in a data center. They account for 30% to 50% of total energy use in less-efficient enterprise facilities (IEA/Coat Zone).
    • The AI Multiplier: AI-focused servers generate significantly more heat than traditional servers, requiring 2 to 4 times the power and, consequently, a massive increase in cooling capacity to prevent catastrophic hardware failure.

    When cooling efficiency drops even by a small percentage, the Power Usage Effectiveness (PUE) of a data center skyrockets. This drop leads to millions of dollars in wasted operational expenditure (OpEx).

    The Corrosion Threat: A Silent Saboteur of Uptime

    While power grids struggle to keep up with demand, environmental factors are attacking the very machines designed to provide relief. Corrosion is a primary cause of HVAC failure, responsible for nearly 40% of equipment failures in industrial settings (CED Engineering).

    In data center hubs—ranging from the humid corridors of the East Coast to industrial zones in the Midwest—cooling coils are under constant attack from:

    • Salt Air & Humidity: Accelerating the oxidation of aluminum and copper.
    • Pollutants & “Electrolytes”: Gaseous contaminants that cause pitting and “formicary” corrosion, which can lead to refrigerant leaks and total system failure in less than a year.
    • Thermal Stress: Constant 24/7 operation at high loads accelerates the mechanical degradation of the bond between HVAC fins and tubes, reducing heat transfer by 15–20% over just five years (IRE Journals).

    Re-Engineering Resilience for the AI Boom

    To meet the goals of the “Americas-first” data center expansion, facilities must shift from a “replace-on-failure” mindset to a “protect-and-optimize” strategy. Coat Zone’s dual-coating approach provides a high-impact, low-cost shield for the infrastructure powering the AI boom:

    1. CoilSafe® & CoilSafe Plus® (Internal Protection): These ultra-thin (8–10 micron) inorganic coatings bond covalently to HVAC coils. Unlike traditional thick coatings, they do not impede heat exchange. By preventing corrosion and “fouling” (the buildup of dirt and microbes), CoilSafe can improve HVAC efficiency by up to 10% and maintain near-factory performance for the life of the unit.
    2. ThermalBlock™ (External Defense): Applied to exterior cabinets and rooftop ductwork, ThermalBlock acts as a radiant barrier that blocks up to 93% of solar heat. By keeping the unit’s cabinet temperature within 10°F of ambient air, it drastically reduces the “thermal load,” allowing the system to run less frequently and consuming significantly less kWh during peak demand.

    Sustaining the AI Boom with ROI

    As Business Facilities highlights, the Americas are leading the charge in capacity, but that leadership requires a foundation of efficiency. Integrating Coat Zone’s coatings can:

    • Reduce cooling energy consumption by 15–30%.
    • Extend the useful life of assets by 50% or more, deferring massive capital expenditures.
    • Deliver a rapid ROI, typically within 12 to 36 months.

    The future of AI is being built today. By protecting the cooling infrastructure that keeps these digital brains alive, Coat Zone is helping ensure that the surge in capacity is matched by a surge in resilience.

  • Coat Zone Turns Circularity Metrics into Reality

    Coat Zone Turns Circularity Metrics into Reality

    The HVAC industry is currently undergoing a massive shift. In December 2025, Trane Technologies, a global leader in climate innovation, announced a bold new roadmap for circularity. They aren’t just talking about “going green.” They are setting hard targets. Targets like generating 10% of revenue from circular products and services and doubling their use of circular materials by 2030.

    But what does this mean for the building owner in Houston, the facility manager in a coastal city, or the industrial plant operator?

    It means the era of “take, make, and waste” is ending. And at Coat Zone, we are the bridge between these corporate sustainability goals and your actual mechanical room.

    The Circularity Strategy: Use Less, Keep Longer

    Trane’s circularity strategy is built on a few key pillars:

    1. Smart Services & Upgrades: Keeping products in use longer.
    2. Optimized Product Lifecycles: Reducing the need for new raw materials (like steel, copper, and aluminum).
    3. Recycled Content: Moving toward a supply chain that feeds back into itself.

    While a manufacturer like Trane focuses on how units are built, Coat Zone focuses on how units survive. If circularity is about “maintaining and prolonging,” then our HVAC coatings are the ultimate circularity tool.

    Doubling Life: The Ultimate Circularity Metric

    Trane is pioneering “Circularity Impact Metrics” to track how its practices drive ROI. At Coat Zone, our metrics have always been simple:

    • Extend useful life by 50% to 100%: By applying our CoilSafe® and ThermalBlock™ coatings, we effectively “pause” equipment degradation.
    • Restore, don’t replace: Instead of the carbon-intensive process of manufacturing a new 20-ton unit, shipping it, and scrapping the old one, we restore the efficiency of your existing asset to near-factory levels.

    Closing the Loop on Efficiency

    A major part of circularity is reducing “embodied carbon”—the emissions associated with making new stuff. Trane is targeting a 40% reduction in embodied carbon by 2030.

    When Coat Zone treats a unit, we are directly supporting this goal. A unit that lasts 20 years instead of 10 represents a 50% reduction in the “manufacturing footprint” of that building’s HVAC needs over time. Furthermore, by reducing energy consumption by 15–30% through improved heat exchange and solar shielding, we reduce the operational carbon—the “Gigaton Challenge” Trane frequently references.

    The ROI of Circularity

    As Mauro J. Atalla, Trane’s Chief Sustainability Officer, noted: “There is no tradeoff between strong financial performance and bold sustainability leadership.”

    We agree. Our clients aren’t just choosing Coat Zone for environmental reasons; they are doing so because deferring a $100,000 capital expense for 5–7 years makes perfect financial sense. It’s “Sustainability with ROI.”

    Moving Forward

    The conversation Trane Technologies has started is vital for our industry. It’s a call to rethink how we value our resources.

    At Coat Zone, we are proud to provide the technology that allows facility managers to meet these new industry standards. Whether you are looking to align with global circularity protocols or simply want to “Run Less with Greater Efficiency,” we’re here to help you close the loop.

  • Go Beyond the Lab with ASTM G50

    Go Beyond the Lab with ASTM G50

    Why ASTM G50 Should Be the Gold Standard for Atmospheric Corrosion Testing

    When evaluating how metals and alloys will perform in real-world conditions, choosing the right test method is crucial. While accelerated laboratory tests have their place, the superior method for determining true, long-term atmospheric corrosion resistance is ASTM G50: Standard Practice for Conducting Atmospheric Corrosion Tests on Metals.

    This testing helps product manufacturers, metallurgical companies, and end users understand the wear and corrosion behavior of specified materials.

    What is ASTM G50?

    ASTM G50 is a comprehensive standard that outlines the general procedures and conditions for exposing metal panels and alloys to real-world weather and atmospheric conditions.

    • Objective: To evaluate the corrosion resistance of metals when exposed to the weather and to assess the relative corrosivity of the atmosphere at specific testing locations.
    • Methodology: It involves placing test panels in defined outdoor exposure sites to accumulate data for comparison purposes.
    • Key Consideration: Recognizing the highly variable and complex nature of the atmosphere (weather effects, industrial factors, natural elements), the standard recommends a multi-year exposure period to minimize the influence of short-term variations and provide a reliable assessment.
    • Quality Control: It mandates the use of control specimens—materials with established weathering characteristics—to ensure the test results are meaningful and comparable.

    The Real-World Relevance of ASTM G50

    The most significant advantage of ASTM G50 is its direct correlation to how a material will actually perform in service.

    • True Corrosivity Data: By exposing materials to actual rain, humidity, temperature cycles, UV light, pollution, and natural salt deposits, the test captures the synergistic effect of these variables. This provides data that is inherently more relevant than data from conditions simulated in a controlled environment.
    • Long-Term Performance: The test accounts for seasonal variability and requires multi-year exposure. The results are highly reliable for predicting a material’s long-term durability and lifespan in a specific atmospheric environment.
    • Material Selection and Site Evaluation:
      • It helps determine the most suitable metal or protective coating for products used outdoors (e.g., in construction, automotive, or infrastructure).
      • It can also be used to evaluate and compare the inherent corrosivity of different geographical locations before large-scale projects are built.

    Why ASTM G50 is Superior to ASTM B117 (Salt Spray)

    When the goal is to predict real-world atmospheric performance, ASTM G50 offers a level of fidelity that the commonly used ASTM B117, Standard Practice for Operating Salt Spray (Fog) Apparatus, cannot match.

    While ASTM B117 (often called the salt fog or salt spray test) is a valuable tool for quality control and detecting gross material defects, it is fundamentally an accelerated laboratory test with severe limitations for performance prediction.

    FeatureASTM G50 (Atmospheric Corrosion)ASTM B117 (Salt Spray/Fog)
    Test EnvironmentReal-world weather (rain, sun, temperature cycles, natural contaminants).Controlled, high-humidity fog of 5% neutral salt solution at constant temperature.
    RelevanceHighly correlated with real-world, long-term outdoor performance.Seldom correlated with performance in natural environments when used as stand-alone data.
    Test DurationTypically multi-year (e.g., 1, 3, 5 years).Typically measured in hours or days (e.g., 24, 100, 1000 hours).
    PurposeEvaluates true corrosion resistance and atmospheric corrosivity.Provides relative corrosion resistance information for comparison in a given test chamber.
    LimitationHigh variability if exposure time is too short.Poor predictability for long-term outdoor use without corroborating field data.

    As the ASTM B117 significance section notes, “Prediction of performance in natural environments has seldom been correlated with salt spray results when used as stand-alone data.” Furthermore, correlation should be considered “only in cases where appropriate corroborating long-term atmospheric exposures have been conducted.”

    The ultimate “corroborating long-term atmospheric exposure” is, in essence, an ASTM G50-style test. The salt spray test simply does not replicate the complex, cyclic drying/wetting, UV exposure, and contamination effects that occur naturally. It creates a highly specific, controlled environment, which is why its results often fail to translate to the real-world performance engineers truly need to know.

    Coat Zone and ASTM G50

    Despite completing 6,000 hours of B117 testing, we believe the G50 evaluation provides a stronger case for the efficacy of CoilSafe®, which is why we conducted an ASTM G50-style marine exposure evaluation. This evaluation included 25,000 hours of natural marine exposure on Galveston Island, one of the harshest coastal environments. Third-party reporting showed that CoilSafe® exhibited complete corrosion resistance, whereas the uncoated coil on the same rooftop showed extensive deterioration consistent with chloride-driven corrosion. Learn more about the results of this evaluation here.

    Final Thoughts

    For any material designed to withstand the elements, relying solely on an accelerated lab test such as ASTM B117 is a risk. ASTM G50 provides the necessary rigor and realism by testing materials in their actual operating environment: the open atmosphere. By adhering to its procedures—including using controls and committing to multi-year exposures—companies can gain confidence that their material’s performance data is not only fast but also accurate.

  • Reviving Aging Infrastructure Through Retrofits

    Reviving Aging Infrastructure Through Retrofits

    When overseeing vast portfolios of aging infrastructure, a critical challenge looms: the degradation of asset value driven by deteriorating Indoor Air Quality (IAQ) and unsustainable energy costs. While the initial impulse may be to prioritize costly, full-system replacements, the smart, sustainable solution lies in strategic retrofitting, specifically targeting the core failure point: your HVAC system.

    The reality is that legacy buildings must compete with modern, high-performance facilities. When tenants and occupants prioritize health and efficiency, an aging asset with compromised air quality and skyrocketing utility bills quickly becomes a liability. This is particularly true in the post-pandemic era, where IAQ has become a non-negotiable metric of building quality and resilience.

    The Dual Threat for Aging Infrastructure: Corrosion and Contamination

    According to Buildings magazine, older infrastructure presents significant IAQ challenges stemming from its foundational systems. The most critical issue lies within the HVAC coils and internal components. Over time, these systems face a dual threat:

    1. Corrosion and Efficiency Loss: In environments with high humidity or industrial pollutants, evaporator and condenser coils are prone to corrosion and fouling. This degradation weakens the critical bond between the fins and the copper tubing, severely impeding heat transfer. An inefficient coil forces the HVAC system to run longer and harder, wasting energy and accelerating equipment wear.
    2. Microbial Contamination: Damp, aged coil surfaces become ideal breeding grounds for mold, mildew, and bacteria. When the HVAC system is the source of contamination, poor IAQ becomes unavoidable, as it circulates particulate matter and potentially harmful biological agents throughout the occupied space. This directly impacts occupant health and productivity, diminishing the asset’s value.

    For an asset owner, replacing an entire HVAC system is often prohibitively expensive and disruptive. The alternative targeted, high-performance retrofit strategy is essential for achieving modern performance metrics without the massive capital outlay.

    The High-ROI Retrofit: A Solution-Focused Approach for Aging Infrastructure

    Coat Zone’s advanced coatings are engineered to transform existing HVAC units into high-performance, long-life assets. This makes them the cornerstone of an intelligent retrofit strategy for aging infrastructure. Our solutions offer a proven path to simultaneously recover efficiency and dramatically improve IAQ.

    1. IAQ and Efficiency Recovery with CoilSafe Plus®

    To address the internal threats to efficiency and health, we recommend CoilSafe Plus®. This proprietary, ultra-thin, inorganic coating is applied directly to the coils. It then wicks deep into the structure to restore the critical heat transfer bond.

    • Efficiency: By restoring heat transfer, CoilSafe Plus® can help bring systems closer to their original factory efficiency. This often results in measurable reductions in kilowatt-hour usage and lower operating costs—the goal of any successful retrofit.
    • IAQ and Corrosion Defense: As an antimicrobial solution, CoilSafe Plus® creates a glass-like barrier that resists the adhesion of mold, mildew, bacteria, dirt, and debris. This permanent defense fights coil fouling and preserves optimal airflow. It also directly addresses the primary source of biological contaminants within the HVAC system, thereby improving IAQ for aging infrastructure.

    2. Asset Preservation with ThermalBlock™

    For units exposed to the elements, our ThermalBlock™ coating provides the external defense necessary to complete the retrofit. Applied to exterior cabinets and ductwork, this thermal radiant barrier blocks up to 93% of solar heat. By reducing the thermal load on the unit’s exterior, ThermalBlock™ reduces HVAC run-time, significantly extending the unit’s useful life and lowering energy consumption, especially during peak demand periods.

    The combination of internal protection (CoilSafe Plus®) and external thermal defense (ThermalBlock™) delivers an integrated, lasting retrofit solution that costs a fraction of unit replacement while providing a rapid, measurable ROI.

    Why Data Center Location Is the Ultimate High-Stakes Decision

    The modern world runs on data, and data runs on data centers. These digital factories are the most important industrial real estate of our time. When a company decides where to plant one of these multi-million, sometimes multi-billion, dollar facilities, it is one of the most consequential decisions they will ever make.

    A data center’s location is not a simple choice. The choice is a high-stakes calculation that balances risk, cost, and access to essential resources. As Artificial Intelligence (AI) and cloud computing explode, the demands placed on these facilities are higher than ever, pushing site selectors into challenging geographic areas.

    For builders and operators, understanding the core factors driving these location choices is critical—and so is preparing the HVAC infrastructure to survive the inevitable environmental trade-offs.

    The Unholy Trinity: Three Non-Negotiable Data Center Location Selection Factors

    The process of choosing a data center site is a game of compromise. There are three core factors that are non-negotiable for success [1, 2].

    1. Power: The Unquenchable Thirst 

    The most important factor is the availability of reliable, affordable, and sustainable power. Data centers, particularly those supporting AI and high-performance computing, are massive consumers of electricity. A typical cloud data center can consume the power of tens of thousands of homes.

    • Why it’s essential: Without a stable, redundant connection to an affordable grid, the center cannot operate profitably or reliably. The demand for low-carbon energy also pushes operators toward regions with abundant renewable resources like hydro, wind, or solar power [5].

    2. Connectivity: The Fiber Lifeline 

    A data center is useless if it’s not connected to the internet’s global nervous system. Site selectors prioritize proximity to major fiber optic routes and internet exchange points to ensure low latency (the speed at which data travels).

    • Why it’s essential: For applications ranging from financial trading to streaming, a delay of milliseconds can mean failure. High-quality, redundant, and diverse fiber access ensures the data center can serve its customers efficiently and remain operational if a single line is cut [2, 4].

    3. Risk and Resilience: Battling Mother Nature 

    Power and connectivity draw data centers to densely populated or resource-rich areas. However, the need for resilience pushes them away from high-risk zones. Locations prone to natural disasters, such as earthquakes, hurricanes, or floods, are often avoided [3].

    • Why it’s essential: Downtime is catastrophic. A strong location strategy requires mitigating physical risk, including avoiding sites near flight paths, chemical plants, or known fault lines [4].

    The Unavoidable Trade-Off: Data Center Location Risk

    In the pursuit of low-cost power and fiber access, data centers are often forced to choose locations with unavoidable environmental challenges. A prime example is the trend of building in coastal regions (for transatlantic fiber) or near hydro-power dams (for cheap energy).

    These strategic choices expose critical HVAC systems to major threats that undermine efficiency and reliability:

    1. High Humidity and Condensation: Coastal locations or those with aggressive cooling strategies (like using large amounts of evaporated water) result in high ambient humidity. This promotes condensation on cold surfaces like cooling coils, ductwork, and air handling unit casings. This moisture is the breeding ground for mold and corrosion [3].
    2. Airborne Contaminants: Locations near industrial centers or coastlines introduce corrosive elements (like salt spray or industrial pollutants) into the cooling air stream. These contaminants attack unprotected metal surfaces, leading to micro-organism growth, fouling, and ultimately, system failure.

    The data center faces premature equipment failure, reduced thermal transfer efficiency (leading to higher energy bills), and a compromised indoor environment if the negative factors aren’t addressed.

    Coating the Core: Mitigating Location Risk with Coat Zone

    Coat Zone’s specialized protective coatings are engineered to directly counter the environmental damage from strategic location choices. They help ensure the HVAC infrastructure lives as long as the digital infrastructure it serves.

    CoilSafe and CoilSafe Plus: Protecting the Heart of Cooling

    The most vulnerable component in any data center is the cooling coil because it is constantly exposed to the air.

    • How they help: CoilSafe and CoilSafe Plus create a durable, ultra-thin barrier that is antimicrobial and highly resistant to environmental corrosion. In coastal or industrial environments salt and pollutants accelerate coil degradation. Our coatings prevent fouling and microbial growth (mold and bacteria) that would otherwise compromise both air quality and thermal transfer. CoilSafe and CoilSafe Plus maintain peak thermal efficiency to directly support continuous, affordable cooling.

    ThermalBlock: Stopping Condensation and Corruption

    Applied to the exterior of air handling units, chilled water piping, or plenum surfaces, ThermalBlock addresses the solar heat load challenge head-on.

    • How it helps: ThermalBlock acts as a superior thermal barrier, blocking up to 93% of solar heat, instantly reducing surface temperatures to within 10°F of the surrounding air, even in peak summer conditions.

    The decision on where to place a data center can be driven by fiber and power. But, the resilience of that investment is determined by the protective measures taken against the chosen location’s environment. Coat Zone ensures that the essential cooling systems, the very lungs of the data center, are protected and optimized, no matter where they are built.
