ZO45K3E-TFD-269

SKU: 8842146

Copeland ZO scroll compressors have been designed for use in R744 (CO2) low temperature refrigeration systems - suitable for usage in CO2-subcritical cascade and booster systems. Increasing environmental concerns about potential direct emissions from HFC-based refrigeration systems into the atmosphere have led to the revival of R744 in the European refrigeration market - regionally reinforced by legislation and taxation schemes. The ZO range has been particularly designed to exploit the characteristics of the R744 refrigeration system keeping efficiency, reliability and liquid handling advantages of the Copeland scroll technology.
