Condensing Units for full range of A2L refrigerants, including ultra-low GWP R1234ze/yf, and lower GWP R455A and R454C

The condensing units, from a German manufacture, offer end users a future-proof solution since all these refrigerants, R1234ze/yf, and lower GWP R455A and R454C, have GWPs below 150, the critical threshold under the F-Gas Regulation.

The units are designed for use in a wide range of applications, including cold rooms, petrol stations and convenience stores, and are available from 1.5 kW to 5 kW in low temperature versions and from 3.5 kW to 16 kW in medium temperature versions, with an operating range spanning -45°C up to 0°C, without requiring liquid injection.

The condensing units are based on highly efficient and reliable compressors with sophisticated capacity control, optimised heat exchangers and variable speed fans and stepless capacity modulation from 50% up to 100% is standard, with 10% to 100% as an option. A wide range of features contribute to efficiency and performance and overall the units offer excellent energy efficiency, reliability, and future-proofing.

Explanatory note: A condensing unit as a minimum consists of a compressor, a condenser and a fan, and it is located outside or where there are several units potentially in a small machine room with ducted outside air and fan cooling. When connected to display units having evaporators it forms a refrigeration circuit.
