Packaged water-cooled water chillers and reversible heat pumps on the cooling circuit with water-cooling system. Range with scroll hermetic compressors and R410A refrigerant gas.
Construction features
• Compressor: hermetic rotary scroll complete with thermal protection and crankcase heater.
• Primary side (user) heat exchanger: adequately insulated stainless steel plates, complete with antifreeze heater and water flow differential pressure switch.
• Disposal unit side (well/mains/geothermal probes) heat exchanger: adequately insulated stainless steel plates, complete with antifreeze heater and water flow differential pressure switch (for THHEY).
• Control: microprocessor electronic control with Adaptive Function Plus logic.
• Structure: made of galvanised and painted steel plate with polyester powder coating.
• The unit is also complete with:
– compressor circuit breaker switches;
– display of cooling circuit high and low pressure;
– Master/Slave control up to 4 units in parallel;
