Water chillers and packaged reversible air-cooled heat pumps with axial fans. Range with scroll hermetic compressors, DC Inverter and R410A refrigerant.
Construction features
• Compressor: scroll type, rotary, hermetic and with Inverter actuation (1+i) complete with thermal protection and casing heater.
• Continuous regulation with high efficiency at partial loads.
• Water side heat exchanger: with stainless steel plates, complete with closed cell polyurethane foam rubber insulation and water flow differential pressure switch.
• Air side heat exchanger: featuring micro-channels (TCAIY) or finned coil with copper pipes and aluminium fins (THAIY).
• Fan: external rotor axial type electric fans with internal thermal protection, accident protection grilles. The electric fans, based on the sizes, are EC fans or fitted with a proportional electronic device for continuous regulation of the rotation speed of the fans.
• 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:
– compressor and fan circuit breaker switches;
– electronic expansion valve;
– display of cooling circuit high and low pressure;
– Master/Slave control up to 4 units in parallel;
– clock board;
– control of Variable Primary Flow (VPF_R).
Versions
• T – High efficiency version with oversized condensing section (TCAITY-THAITY).
• Q – Super-silenced version complete with compressor technical compartment soundproofing, reduced speed fans and oversized condensing section (TCAIQY-THAIQY).
