High efficiency air cooled water chillers and packaged reversible heat pumps with plug-fan type centrifugal fans with EC motors. Range with scroll hermetic compressors and R410A refrigerant.
Construction features
• Compressor: scroll type, rotary, hermetic complete with thermal protection and casing heater.
• 2 or 3 capacity steps depending on the models, to obtain excellent load modulation along with high energy 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 finned coil with copper pipes and aluminium fins.
• Plug-Fan type centrifugal electric fans with EC motors, equipped with internal thermal protection arranged in single row with horizontal outlet.
Horizontal outlet of the evaporation condensing air opposite side to finned coil or vertical outlet can be easily transformed on site.
• Proportional electronic device for continuous fan rotation speed regulation up to an outdoor air temperature of –15°C in chiller mode and up to an outdoor air temperature of 40°C in heat pump mode.
• Control: microprocessor electronic control with Adaptive Function Plus logic.
• Load-bearing structure and panelling made of painted and galvanised sheet steel (RAL 9018); galvanised sheet steel base
• The unit is also complete with:
– fan and compressor circuit breaker switches;
– 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).
