Airsys Cooling Technologies opened its new global headquarters, which will serve as the company's hub for high-efficiency, zero-water cooling technologies designed to support the rapid growth of artificial intelligence infrastructure and edge computing deployments. The ACHR News editorial coverage highlighted Airsys as a company positioning directly at the intersection of two of the most significant technology trends in commercial HVAC: AI infrastructure cooling demand and water scarcity constraints that are making water-intensive cooling approaches increasingly problematic.
Water scarcity is an underappreciated constraint on data centre development that is becoming increasingly relevant as hyperscaler construction concentrates in Sunbelt and western US geographies where water availability is limited. Data centres that rely on evaporative cooling or water-cooled chiller systems consume millions of gallons of water annually — a consumption rate that is creating regulatory scrutiny, community opposition, and water permitting challenges in drought-prone markets.
What Zero-Water Cooling Means in Data Centre Context
The term 'zero-water' in data centre cooling refers to cooling approaches that do not consume water through evaporation — contrasting with traditional cooling tower, evaporative cooling, and chilled water approaches that consume water as part of the heat rejection process.
The primary zero-water cooling approaches applicable to data centre applications:
• Air-cooled chillers and DX systems: Reject heat to outdoor air directly through air-cooled condensers — no water consumption, but lower efficiency in hot climates where outdoor air temperatures are close to the required supply air temperature
• Liquid-to-air heat rejection: Circulate server waste heat through liquid cooling loops to outdoor dry coolers that reject heat without evaporation — maintaining the efficiency advantages of liquid cooling while eliminating water consumption
• Rear-door heat exchangers and chip-level cooling: Direct-to-chip and immersion systems that capture waste heat at the source and reject it through closed liquid loops rather than evaporative cooling infrastructure
• Thermoelectric and advanced solid-state cooling: Emerging technologies that use thermoelectric principles rather than refrigeration cycles for heat management — applicable at component level but not yet at data centre scale
Airsys Cooling Technologies' new global headquarters serves as the hub for zero-water, high-efficiency cooling technology development for AI data centres and edge infrastructure — addressing a growing constraint on data centre development as water scarcity and permitting challenges limit evaporative cooling approaches in drought-prone Sunbelt and western US markets.
The Water-Energy Tradeoff in Data Centre Cooling
The water-versus-energy tradeoff is the central design challenge in data centre cooling. Evaporative cooling is highly efficient — it uses water's latent heat of evaporation to reject heat, which is thermodynamically effective and energy-efficient. But it consumes water at a rate that is environmentally and regulatorily challenging in many markets.
Air-cooled approaches avoid water consumption but typically require more electricity to achieve the same heat rejection, because rejecting heat to air is thermodynamically less efficient than rejecting heat through evaporation. The efficiency penalty from air-cooled versus water-cooled operation can range from 10 to 30 percent of energy consumption, depending on climate and system design.
Technologies like those Airsys develops seek to minimise this tradeoff — achieving efficiency close to water-cooled approaches without the water consumption, through advanced heat exchanger design, optimised airflow management, and system integration that reduces the energy penalty of air-cooled rejection.
For the HVAC industry, the growth of zero-water cooling as a design priority creates demand for specialised equipment — different from the chillers, cooling towers, and packaged systems that dominate traditional commercial HVAC — and for contractors who understand the specific design and commissioning requirements of zero-water data centre systems.
Frequently Asked Questions
What is Airsys Cooling Technologies?
Airsys Cooling Technologies is a provider of high-efficiency, zero-water cooling systems for AI data centres and edge infrastructure, having opened its new global headquarters to serve as the hub for its technology development. The company addresses the growing constraint that water availability places on data centre cooling in drought-prone markets.
Why is zero-water cooling important for data centres?
Traditional data centre cooling approaches (cooling towers, evaporative systems, chilled water) consume millions of gallons of water annually. As data centre construction concentrates in Sunbelt and western US markets with water scarcity challenges, zero-water cooling approaches that reject heat without evaporation are becoming more important for regulatory compliance, community acceptance, and water permitting.
