WLA Precision R410 Cosmotece Chiller
Structure: galvanised and polyester powdercoated structure. Colour std RAL7035 orange peel.
Compressors: scroll compressors with overload thermal protection, rubber antivibration mounts and oil charge.
Evaporator: AISI 316 brazed plate heat exchanger complete of external anti-condensate insulation. The exchange is made through two indipendent alternating water/freon refrigerant circuits with cross flow to maximise the efficency. The evaporator is complete of differential pressure switch and antifreeze alarm.
Condenser: heat exchange coil with aluminium fins and copper tubes. The coils are complete with integral subcooling circuit to assure the correct operation of the components.
Fans: helical fans direct coupled to electric motor. The fan is placed into a nozzle to increase the efficiency and reduce the noise. The fan speed control is included.
Refrigerant circuit: multiple refrigerant circuit with
- dehydrator filter
- sight glass
- high pressure switch
- low pressure switch
- compressor discharge shut off valve
Electrical panel: includes
- main insulator switch
- compressor circuit breaker
- fan overload circuit breaker
- control contactor
- fan control contactor
- phase cut fan speed control
- C2020 controller
These units are chillers for process cooling that are not covered by the regulations for MT (Medium Temperature – EU 2015/1095) and HT (High Temperature – EU 2016/2281).
The working limits for the fluid temperature, are:
- base units: +13°C ÷ +25°C
- units for low water temperature: -5°C ÷ +1°C
