DCA-W series are air-cooled chiller units; "Desert- Type" unit are members of the two compressors with two independent refrigerant circuit with modular structure. Thanks to the screw compressors technology, 4 step operation control can be obtained from a single compressor and totally 8 steps control for two circuit units (%12,5 - %100), whereby to provide high energy savings leads to the partial heat load. This ultimate series are able to work under high ambient temperature climate up to 60 °C without losing high-efficiency performance with step control, maximum physical strength and low sound level dB(A). Due to the wide range of cooling capacity, big Industrial applications and HVAC systems are extensively used. All unit components are selected from the well-known and easily accessible brand in world-wide. Therefore, If necessary easy to find spare parts in locally. Also for larger application, units are able to use as a modular system with ERACO Intelligent Controlling System (IND-SCREEN) Easy access to the functional parameters on the 7” color display LCD screen as a standard.
