CS PRO series for process heating and district heating networks (R600a)
CS PRO series for process heating and district heating networks (R600a)
The compact screw compressors in this CS PRO design are specially designed to operate with the natural, low-GWP refrigerant isobutane (R600a). Isobutane is a hydrocarbon that is exceptionally well suited to heat pump applications. These models were developed for process heating systems and district heating networks and allow for liquid outlet temperatures of up to around +95°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.
An enhanced compressor protection device (SE-i1) protects the compressor while operating parameters, such as pressures and temperatures, are monitored and recorded in real time.
As isobutane is a flammable refrigerant in the A3 safety class, these compressors are only available to OEM contractors who have experience working with flammable refrigerants.
