The standard and digital models from the Copeland™ ZR*KRE scroll compressor range for R450A and R513A are designed for comfort, precision and process cooling as a replacement for R134a. They are built to ensure reliability with refrigerants containing HFOs. They feature a wide operating envelope, with evaporating temperatures from -20°C to +25°C, and condensing temperatures from +10°C to +75°C. ZRD*KRE models with digital technology provide continuous, stepless modulation from 10% to 100%. The ZR(D)*KRE range fulfils the needs of industrial applications with new refrigerants.
ZR Copeland scroll compressor were developed or comfort and process/precision cooling applications using R513A, R407C and R134a.
Applied in the air conditioning and comfort industry for water chillers, rooftops and close control unit applications, scroll compressors are now the most used compression technology replacing reciprocating and screw compressors due to its undeniable superiority. Several, fully Copeland qualified, multiple compressor assemblies (tandem and trio) are available to allow the use of Copeland scroll compressors into large capacity systems (ex. up to 500kW air cooled chillers) able to deliver optimal comfort, low operating cost with higher seasonal efficiency (SEER). To support the new market needs of customers, Emerson offers scroll compressors for R513A, a low-pressure refrigerant with a low GWP of 631. These ranges are able to reach 5K Superheat which allows better system performance optimization and cost.
The range of products goes from the ZR24 (2hp) to the ZR380 (30hp) for R407C and R134a and from ZR24KRE (2hp) to ZR190KRE (15hp) for R513A, R407C and R134a.
