XC-XXS series screw style chillers host used German BITZER semi-hermetic screw compressors have outstanding technical characteristics in single-compressor and two-compressor models. It is applicable to R22, R407, R134a and other refrigerants. High efficiency horizontal shell and tube condenser and evaporator have "BR1" state permission to create a pressure vessel, heat stability and maintenance convenience. An advanced micro-computer controller, a powerful, high-speed embedded microprocessor performance is much higher than similar products used in the single-chip machine.
Features
·Germany semi-hermetic screw compressors, bearing longevity will ensure long-term operation;
