The reversible R290 heat pump from Refra has heating power from 20kW to 400kW, and is designed for commercial and industrial buildings with low to high power demand. With high cooling/heating capacities and many possible extra features this product is widely used in various factories, immense supermarkets and warehouses. The Refra reversible heat pump can be designed on various steel frames – from a compact welded frame to a large modular container as long as 13 meters. Frame construction is assembled with high-quality EC fan motor technology, finned tube and/or microchannel heat exchangers, scroll, reciprocating or screw compressors. Units can be made with one to three circuits to ensure continuous system operation in case of emergency – if one circuit is damaged, the others can still use the remaining unit capacity to service the end user.

The galvanized steel and powder coated frame with a reliable insulation material ensures proper unit protection and noise reduction. An additional 50 mm rock wool material can be supplemented for a super silent unit operation with double insulation. To prevent ice formation, the frame can be equipped with special water drain outlets or larger, raised coils to simplify the defrosting process and allow water to drain freely. This solution helps avoid additional platform placement costs as you can install the unit directly on the ground.

The R290 reversible heat pump units are a part of an environmentally friendly product group from Refra, as they are made using hydrocarbon refrigerant. Such solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

Please note, that these reversible heat pumps can be fully customized according to the needs of a customer.
