AACHEN, GERMANY, September 30, 2013 – Emerson Climate Technologies has released two new Copeland Scroll compressors for low temperature CO2 subcritical applications. The models ZO21K5E and ZOD34K3E (Digital scroll) have a cooling capacity1 of 4.7 kW and 7.4 kW. They complement the existing range of six ZO(D) scrolls with a maximum cooling capacity of 22.1 kW. In addition, the rated stand-still pressure levels of all scrolls for the refrigerant CO2 are improved to 30 bar (low side) and 45 bar (high side). This release is an important step to fulfill requirements from the refrigeration market. Copeland Scroll compressors are a perfect fit for booster packs used in retail applications where capital cost is key. They also represent a good opportunity for hybrid systems using R134a, R407A or R407F on the high side. The Digital model ZOD with continuous capacity modulation from 10…100% is a flexible and affordable alternative to inverter solutions.
