The HEW-S series tandem scroll compressor chiller devices, specially developed for HVAC systems, are high efficient water cooled units. These are particularly preferred at interior operations since they require very less space thanks to their minimized dimensions. They actuate their compressors according to the cooling need by their multiple compressor structure and provide thus energy savings. 7” colour LCD touch-screen monitor, flow control system, compressor equal aging software are included as a standard.
