CTM ejector is an electrically controlled multi-ejector designed specifically for the warm climate operation of transcritical CO2 systems in commercial refrigeration applications. Capable of recovering energy while controlling the high pressure of the transcritical application, the ejector improves energy efficiency by 20 percent in the warmest ambient conditions, says the manufacturer. This is accomplished by employing energy recovered from the gas cooler and transferring it to increase the pressure of gas being compressed by parallel compressors, thus reducing overall compressor load. The product won the 2017 AHR Expo Innovation Award in the refrigeration category.
