CS PRO series for process cooling (R290, R1270)

CS PRO series for process cooling (R290, R1270)

The compact screw compressors in this CS PRO design are designed to operate with the natural, low-GWP refrigerants propane (R290) and propene (R1270).
These models were primarily developed for process cooling applications with and without heat recovery and allow for liquid outlet temperatures from roughly -25°C up to +70°C. The CS PRO series differs from the standard CS series due to its special electrical accessories, oil charge, safety devices and internal lubrication system.
As propane and propene are flammable refrigerants in the A3 safety class, these compressors are only available to OEM contractors who have experience working with flammable refrigerants.

CE
Classification: ‘No sources of ignition in normal operation’
- In normal operation with no faults, the product and its components contain no sources of ignition that could ignite class A3 flammable refrigerants from Group IIA under IEC 60079.
Classification: ‘Durably technically tight’
- The product has increased tightness pursuant to EN 1127-1 and is therefore considered durably technically tight.
- If the product contains flammable gases, this classification means that no ATEX zone has to be assumed around the component.
EAC
