HEAT PUMPS VA Series air/water range 145 kW to 258 kW - CHILLERS A Series air/water range 132 kW to 235 kW with Axial Fans R-410A
Standard technical/construction specifications:
The VA/A Series units have been designed for the production of hot and cold water for use in heating, conditioning and process manufacturing systems (on request the units may also work with glycol water) and comprise:
- an AISI 316 stainless steel frame, with adjustable anti-vibration feet and condensate tray, with separate compartment to protect all components;
- aluminium alloy panels lined with insulating/soundproofing material;
- coil protections in hail-resistant aluminium alloy;
- electrical panel with an IP rating of 55, with phase sequence relay and door lock, control and power distribution board with microprocessor, recorded events/alarms, on board or remote terminal;
- coils with hydrophilic fins for optimal air flow, standard operating range -10 °C / +45 °C outdoor air;
- scroll compressor(s) which work with HFC R-410A, HP + LP pressure gauges, liquid receiver (and liquid separator only for the heat pump);
- axial electric fan(s) with brushless permanent magnets. Class “A” energy rating with low voltage integrated regulation;
- exchanger with braze welded plates, electromagnetic-operated flow meter, mesh filter, on/off valves, expansion tank, safety valve, pressure gauge, air vent, water outlet standard temperature range +6 °C +50 °C;
- in-line centrifugal circulation pump, class “A” energy rating;
- integrated storage tank(*) in 316 stainless steel with 19 mm thick panelling and water discharge valve.
Design, manufacture and testing are all carried out in-company, guaranteeing quality products.
