ENE-W series hybrid units have similar properties to the ENE-S series, however, differ in terms of compressors. Units of this series equipped with screw type compressor rather than scroll comprise of air-cooled chiller and dry-cooler units operating in a compact structure, connected to a single unit and a common control system. ENE-W series hybrid units, prepared especially for the processes where electricity saving is aimed, ensure that free cooling operates for a long time in cases where low air temperature and high process water temperature is required and thus provides high levels of electricity savings. All required working modes are managed sensitively by the “freecooling kit” in the device, leaving no need for any user intervention.
