In addition, the German manufacturer has extended its existing range of R1234ze water-cooled Quantum G chillers up to a cooling capacity of 2MW. The Quantum G was introduced late last year and is one of a select few chillers designed for the low GWP HFO refrigerant R1234ze.
During the course of this year, Cofely Refrigeration says it will expand the Quantum G series with an air-cooled Quantum G offering a cooling capacity of up to 1.25MW. This air-cooled series will also be operated with the refrigerant R1234ze and similarly use the oil-less Danfoss Turbocor compressor. In addition, the air-cooled Quantum G will also be capable of being expanded with free-cooling modules.
