Solis is a high-capacity reversible heat pump designed for industrial and commercial sites with large energy needs. With heating capacities from 100 kW to 400 kW and cooling from 70 kW to 280 kW, it offers a reliable dual-purpose system that eliminates the need for separate heating and cooling equipment.

Using R290 refrigerant and full-inverter technology, Solis is part of Refra’s energy-efficient and environmentally conscious product line. It can operate in heating mode at ambient temperatures down to -15°C, making it suitable for year-round use in supermarkets, factories, and warehouses.

The system can be configured with one, two, or three circuits to ensure continued operation. If one circuit fails, the remaining ones can keep the unit running, helping to avoid downtime.

The modular frame is built with EC fan motors, a choice of finned tube or microchannel heat exchangers, and scroll, reciprocating, or screw compressors. Larger raised coils help water drain easily and improve the defrost process. The galvanised, powder-coated steel frame is insulated with 20 mm of non-flammable PU foam, with an optional 30 mm layer of rock wool for quieter performance.

Solis supports natural refrigeration systems and R290 heat pump systems and is available through Hussmann Australia.
