Air cooled water chillers and reversible heat pumps with axial fans. Range with scroll hermetic compressors and R410A refrigerant.
Construction features
• Compressor: scroll type, rotary, hermetic complete with thermal protection and casing heater.
• Up to 6 capacity steps with high efficiency at partial loads.
• Water side heat exchanger: with stainless steel plates, complete with closed cell polyurethane foam rubber insulation, water flow differential pressure switch and Victaulic fittings.
• Air side heat exchanger: featuring micro-channels (TCAEY) or finned coil with copper pipes and aluminium fins (THAEY).
• Fan: external rotor axial type electric fans, equipped with internal thermal protection, accident protection grilles and a proportional electronic device for continuous fan rotation speed regulation (T version; fans with an EC motor are standard in the Q version).
• Control: microprocessor electronic control with Adaptive Function Plus logic.
• Structure: load-bearing structure made of galvanised and painted steel plate with polyester powder coating.
• The unit is also complete with:
– fan and compressor circuit breaker switches;
– display of cooling circuit high and low pressure;
– electronic expansion valve;
– clock board;
– Master/Slave control up to 4 units in parallel;
– control of Variable Primary Flow (VPF_R).
Versions
