Refrigerant
- Natural hydrocarbon refrigerant isobutane (R600a) with low global warming potential
- A3 safety class (flammable)
Product range
- 17 models from 197 to 1120 m³/h at 50 Hz
General applications
- Process heating and district heating applications with liquid outlet temperatures of up to around +95°C
- Large-scale commercial and industrial heat pumps
Special requirements
- Upon request, the CS PRO series can be supplied in a range of ATEX designs for installation in zones with explosion protection requirements.
Certifications
- 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
