Glycol-free chiller

Walter Meier (Climate UK) has introduced a glycol-free version of its Blue Box Zeta Echos FC free cooling chiller. It is said to be capable of delivering up to 35% energy savings over conventional air cooled chillers and is suitable for applications such as data centres where chillers operate 24 hours a day.

The chiller has two physically separated hydraulic circuits, using glycol for the free cooling coil and pure water to the evaporator and indoor units. Efficiency is further enhanced by the Free Cooling system which has a single fan section and uses a design that locates the condensing coil and the free cooling coil at opposite sides of the unit.

Walter Meier believes the Zeta Echos units to have the highest Seasonal Energy Efficiency Ratio (SEER) in their class.
