Emerson Climate CO2 solutions are built according to the latest technology standards while maximising operational performance and efficiently addressing safety issues.
Emerson CO2 comprehensive solutions comprised of the following:
Emerson offers two distinct types of compressors designed for the specific needs of CO2 applications which therefore aim to take the maximum advantage of the specific characteristics of CO2 systems.
ZO range Copeland Scroll™ compressors for CO2-subcritical:
Copeland™ Stream semi-hermetic compressors for CO2:
High quality flow controls and electronics
Emerson produces a variety of valves, flow controls and oil regulators which can satisfy a wide range of needs related to subcritical and transcritical CO2 systems. Amongst others, Emerson products include:
Emerson electronic controllers for efficient system management
The inclusion of Dixell electronic controllers adds value to the Emerson Climate Technologies CO2 solutions by optimizing compressor and cabinet management. Solutions combining the iProRACK programmable controller with the XEV20D controller manage the compressor pack and maintain operating efficiency; while systems combining the iProRACK with XEV32D effectively manage low and medium temperature levels of CO2 hybrid systems.
Advantages of CO2 solutions made by Emerson Climate Technologies:
Why develop solutions for CO2 refrigeration systems?
Environmental concerns regarding the impact of greenhouse gas emissions coupled with legislation developments have increased the market potential of using CO2 as a refrigerant. However, since the use of CO2 in refrigeration necessitates high operating pressures, there is scope for redesigning refrigeration systems so as to maximize the exploitation of CO2 benefits.
