ESK-components have been used in the past from manufacturer, system
installers and universities for CO2 pilot refrigeration systems and laboratories.
In respect of the exclusive welding technique in the ESK production
the transfer of CO2 component specifications was easy.
According to individual technical requirements, components are mainly
offered for two stage cascade systems with CO2 as the refrigerant in the
low stage. In Denmark,Norway and Finland ESK-oil control systems for parallel
compressor operation work successfully with CO2. Systems are
applied for supermarkets and food freezers.
