Water chiller WCH

Chillers (water cooling units) are compact units adapted for fresh water or brine condenser cooling. Depending on needs, it is possible to offer dedicated, customised version of the chiller, made of special materials (eg low-magnetic version), special protection (eg shock absorbers), non-standard power supply, control, loads or construction. Chillers consist of the following components: Compressor Depending on the efficiency and needs, it is possible to produce aggregates with reciprocating compressors, screw compressors (semi-hermetic or open) or Scroll compressors. Condenser As a standard, we use shell and tube condensers adapted for cooling with fresh water (copper low-finned tubes), brine or sea water (low-finned copper-nickel or brass tubes). Thanks to the use of outside and inside finned tubes, the condenser obtains better heat transfer parameters and thus smaller overall dimensions. Evaporator It is possible to use shell-and-tube or plate evaporators. If required, the evaporator can be made of stainless steel. The evaporator's inlet and outlet temperature sensors, flow sensor and anti-freeze sensor are used to control the water flow through the evaporator. Refrigeration circuit Chiller unit is equipped with: shut-off valves, filter dryer, electronic expansion valves, high and low pressure gauges, pressure transmitters, solenoid valve and safety valves. Microprocessor controll The controller has, among others the following functions: Maintaining the chilled water temperature at the outlet of evaporator Anti-freeze protection Compressors’ control and timer for their work Regulation of the efficiency level Signals from a remote control system
