China Screw Chiller,Screw Chiller Manufacturer
ECMC-W series screw type water-cooled central chillers adopt Bitzer compressor, which is made-in-Germany and semi-hermetic twin screw type. You can choose from single-compressor chillers and double-compressor chillers.For refrigerant, you can choose R22 or R134a. The advanced controller with built-in-microcomputer has powerful and excellent performance.
1) Semi-hermetic twin screw compressor is made in Germany with long service life.
2) Stepless compressor output capacity adjusting function are designed to save power.
3) Evaporator and condensor has high effient heat exchanging peformance with easy maintenance.
4) Extendability of the controller makes upgrade of both hardware and software much easier.
5) "Wachdog" technology makes microprocessor able to diagnose and solve problems automatically.
6) 512K memory for programs and 128K off-power data storage.
7) Special touch screen panel, long service life more than 10 years.
8) Function of fault query and fault statics, convenient to analysis the fault and make improvement.
9) Able to monitor the setting fo actual temp. and display temp. trend in hours or daily.
10) Support multi-language.
