Cooling Compressor: 1 or 2 hermetic or semi-hermetic reciprocating compressors are used according to the capacity.It can work according to all gases. Condenser: It is produced as high efficiency copper tube and aluminum lamella. The unit is calculated by special program according to the climatic conditions to be studied.The high-quality axial fan according to the capacity allows condensation of the refrigerant flowing through it. Evaporator: Shell&tube type producing, a special high-efficiency copper tubing with steel mirror is determined to holes by tube expander. The outer body is insulated with special rubber insulation. Electrical Control Panel: Control of the system is carried out through this board.It is equipped with suitable capacity and number of switches, contactors, thermal, fuse, switch and similar electric shafts for fully automatic operation of the system. Cooling Circuit Elements: Dryer, sight glass, electronic expansion valve, solenoid valve, pressure proceses, flow-switch, cooling valves, water and air discharge valves are used for proper operation of the system. Digital Thermostat Control Unit: The digital thermostat control unit controls the water inlet and outlet temperature values and possible fault conditions in the system. In addition, the operating hours of the compressors are automatically compensated. Technical Specifications 1 – Values are based on evaporator entering/leaving eater temp. 12°C/7°C and ambient temperature 30°C. 2 – Values are based on freefield conditions in 10 meter distance.
