The Grundfos RC pump is said to be the first in the world to have been designed and optimised for use with CO2 as a refrigerant. It uses about a third of the energy of a standard centrifugal pump for the same purpose. This performance is achieved by utilising variable-speed capacity control and intelligent pump protection. Grundfos sees potential for this pump in applications such as large retailers that base their stores on refrigeration systems using CO2.
