Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line.

Ultra-compact frame construction is assembled with high-quality EC fan motor technology, scroll or reciprocating compressors and a finned tube or microchannel condenser. To prevent ice formation, the frame is equipped with special water drain outlets, which are required to ensure a proper defrosting process. It is also recommended to place the unit on a platform in order to leave some space underneath for water to drain. The galvanized steel and powder coated frame with a reliable insulation material ensures proper unit protection and noise reduction. An additional 30 mm rock wool material can be supplemented for a super silent unit operation with double insulation.
