Cooling That Saves More Than Energy
Green Web Hosting runs on infrastructure built for precision and efficiency. Cooling is a major power draw in traditional data centers, but our partner facility, Netwise London East, flips the script with adiabatic and evaporative systems that radically reduce environmental impact.
Evaporative cooling works by harnessing water evaporation to lower air temperature, nature’s oldest air conditioning trick, modernised. Warm air passes over moist surfaces, and as water evaporates, it absorbs heat from the air. The result: cooler air entering the server halls with minimal mechanical intervention. Netwise uses a mix of indirect and hybrid cooling systems to balance efficiency and humidity control.
Adiabatic cooling refines this even further. Rather than continuous misting, the system runs dry for most of the year and activates its cooling spray only when ambient temperatures rise. Incoming air is pre-cooled before it hits the heat exchangers, lowering energy demand without excessive water use. It’s selective, smart, and sustainable, reducing water usage by up to 90% compared to older evaporative methods.
The result? Less reliance on compressors. Lower cooling costs. And a dramatically reduced carbon and water footprint. These systems help Netwise hit its ultra-low PUE target of 1.05 - world-class by design, and verified by the Green Web Foundation.
We don’t host on legacy systems. We host on infrastructure that listens to the planet as much as it serves the web.
