Heating & Cooling

Products Name: Screw Type Water-cooled Chiller (AMC-WS Series)
AMC-S Series screw type central Chillers adopt German-made BITZER with half-closed and twin screw compressors, models with one or two compressors, suitable for using R22 and R407C refrigerants; equipped with high efficiency tube-in-shell type condenser and evaporator ensure stable heat exchange and convenient maintenance; advanced controller with built in microprocessor which has a powerful and excellent performance.
AMC-S centralized Water-cooling System are main composed of compressor, condenser, evaporator and expansion valve. It is adopted single-stage vapor compression refrigeration system, by the principle of inter-conversion between gaseous and liquid refrigerator, to absorb and release heat. So that, achieving the results of refrigeration.
Features Specifications:
> Half-closed, double screws compressor are made in Germany with long service life.
> Stopless compressor output capacity adjusting function are designed to save power.
> Evaporator and condenser built strictly according to national standards.
> Extendibility of the controller makes upgrade of both hardware and software much easier.
> "Watchdog" technology makes microprocessor able to automatically diagnose and solve the problems.
> 512 K memory for programs and 128 K off-power data storage.
> Special touch screen panel, long service life more than 10 years.
> Function of fault query and fault statistics, convenient to analysis the fault and make improvement.
> Able to monitor the setting of actual temp and display temp trend in hours or daily.
> Support multi-language.
