High power reversible heat pumps with the heating power from 100 kW to 400 kW are designed for industrial and commercial buildings with large power demand. Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line. With high cooling capacity and many possible extra features these products are widely used in various factories, immense supermarkets and warehouses. These pumps can be used for heating purposes at ambient temperature of -15°or higher as well as for cooling purposes with the capacity of 70 kW to 280 kW. This dual solution is very efficient in terms of price, installation and space, as there is no need to install two separate systems.
CJ heat pumps 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.
Comprehensive modular frame construction is assembled with high-quality EC fan motor technology, finned tube and/or microchannel heat exchangers, scroll, reciprocating or screw compressors. Larger, raised coils are set to simplify the defrosting process and allow water to drain freely. The galvanized steel and powder coated frame with a reliable insulation material ensures proper unit protection as well as noise reduction and can be produced up to 13 meters in length. An additional 50 mm rock wool material can be supplemented for a super silent unit operation with double insulation.
