Direct expansion type adopts direct expansion type evaporator,semi-hermetical twin screw compressor and tube-and-shell condenser.Standard power source is 380V/3N /50Hz.400-415V voltage is optional. Single compreesor is for 255-860kW. Dual compressor is for 970-1490kW.Stepless capacities can be customized.
●olyair screw chiller is equipped with the 3rd generation industrial compressor that has the latest advanced 5-6 asymmetry dentiform Semi-hermetic Screw Rotors.
●The rotors are processed by high-precision CNC and each part is well-proportioned and none-gap matched.
Microprocessor control as standard on all the units. A display illustrates the machine’s operation status and programmable parameters (set point) e.g.water temperature and refrigeration pressure and temperature
