BITZER's multi-award-winning ECOLITE condensing units are now available for use with a full range of A2L refrigerants, including ultra-low GWP R1234ze/yf, and lower GWP R455A and R454C.
Kevin Glass, Managing Director of BITZER UK, says: "ECOLITE 2.0 offers end users a future-proof solution since all these refrigerants have a GWP below 150, the critical threshold under the F-Gas Regulation. In the case of HFO R1234ze/yf, the GWP is just 1."
The units are designed for use in a wide range of applications, including cold rooms, petrol stations and convenience stores, and available from 1.5 kW to 5 kW in low temperature versions and from 3.5 kW to 16 kW in medium temperature versions. The operating range spans -45°C up to 0°C, without requiring liquid injection.
Despite its competitive price point, ECOLITE units are based on highly efficient and reliable BITZER ECOLINE compressors with sophisticated capacity control, optimised heat exchangers and variable speed fans.
ECOLITE 2.0 delivers improved energy efficiency through a combination of advanced technology and design features. Compressor capacity is managed by quick reacting CRII-VARISTEP control, developed by BITZER as a lower cost but highly effective alternative to expensive inverter-based systems.
It enables proportional modulation of compressor output in response to changes in load and system conditions. This gives stepless capacity modulation from 50% up to 100% as standard, and 10% to 100% as an option.
