PRODUCT INFORMATION OF DANFOSS Copeland 30 ZFI122KQE-TED-523/R404A low temperature freezer cold storage compressor
Features and advantages of ZFI122KQE-TED-523 (excerpt):
• ZF, ZFI series compressors can operate at condensing temperature as low as 4.4°C, providing high seasonal energy efficiency ratio
• The dynamic discharge valve on the compressor can adjust the discharge pressure of the compressor according to the requirements, prevent the recompression of the gas in the compressor, and improve the energy efficiency considerably under the condition of high pressure ratio
• Gas injection enthalpy increase technology makes the energy efficiency ratio of ZFI compressors higher than that of single-stage compressors in low temperature applications, with excellent performance
Emerson Copeland Compressor ZFI122KQE-TED-523
Compressor protection:
• ZF, ZFI series compressors have built-in motor protection to prevent motor overheating caused by phase loss or insufficient refrigerant charge
• ZF series is equipped with DTC liquid injection valve to control compressor discharge temperature
• ZFI series can be equipped with Emerson’s EVI gas injection enthalpy accessory to control the gas injection enthalpy loop, and at the same time ensure that the compressor operates at a safe discharge temperature
