PENSUM Air: our flexible air-cooled chiller
Our PENSUM Air air-cooled chillers are the benchmark in the medium output range from 50 to 400 kilowatts. This is because the series utilises the future-proof refrigerant R-454B with a low GWP value of 466 - and therefore helps users to improve their ecological footprint.

PENSUM Air: Pioneering refrigeration solution for every need
The unique design and innovative configuration ensure that the PENSUM Air chiller cools efficiently and reliably with R-454B refrigerant - and with a high degree of flexibility. This is the quality you have come to expect from ENGIE Refrigeration.
For a medium output range of 50 to 400 kilowatts, PENSUM Air offers the ideal cooling solution for medium-sized office buildings and public facilities such as hospitals. Here, the air-cooled chillers are already "ready to use" in the standard configuration and do not require any reconfiguration - but can be individually expanded and customised with add-ons such as specific configuration packages and various warranty and service options.
The four lines "Basic Cool", "Free Cool", "Super Silent" and "Reversible Heat", each with up to 18 models, will fulfil any on-site requirement you may have.
Basic Cool
Start cooling immediately: That is the credo of the Basic Cool. The compact ready-to-use line impresses in the output range from 60 to 270 kilowatts. The models are equipped with two compressors on a single circuit - ideal for maximising efficiency at partial load. As soon as a cooling capacity of 290 to 390 kilowatts is required, four compressors are used on two circuits.
Super Silent
Ultra-quiet and maximum efficiency: With the Super Silent line, you fulfil the strict requirements for low noise emissions. We guarantee this at a technical level by regulating the speed of the fans. The line starts with an output of 50 kilowatts.
Free Cool
The name says it all, because free cooling reduces electricity costs and is also climate-friendly. The air-cooled chillers in the Free Cool range are also soundproofed and are ideal for use in noise-sensitive areas.
Reversible Heat
Cooling and heating with one machine? With the PENSUM Air heat pump, this is exactly what is possible. This saves costs and protects the environment. All models are particularly cost-efficient and quiet.
All PENSUM Air models use the future-proof refrigerant R-454B, which has a low GWP value of 466. This is below the GWP of <500, which makes it robust against the requirements of the F-Gas Regulation. If you opt for a machine with R-454B refrigerant, the impact on the environment is reduced by 78 per cent compared to a machine with R-410A refrigerant.
In addition to the R-454B refrigerant, the outstanding quality of our PENSUM Air air-cooled chillers ensures long-term reliability - from the housing and refrigeration circuit to the fans, control panel and control technology.
Our air-cooled chillers are customised to your needs: Depending on your individual requirements, you can choose from a wide range of configuration options:
- Integrated hydraulic modules and installation accessories: Inside, PENSUM offers plenty of space for accessories and hydraulic options, such as pumps and buffer tanks in various configurations or installation accessories such as Victaulic couplings.
- Master/slave operation: A choice of seven different operating modes for master/slave control enables optimum performance customisation and maximum availability of up to six PENSUM Air machines.
- Green Heat Recovery: This technology makes it possible to utilise the heat emitted by the condenser for other purposes. This makes up to 40 per cent of the heat output reusable under nominal conditions.
- Glycol collection system: The tested system not only ensures safety in the event of an accident, but also prevents oils and water-glycol mixtures from being flushed out. It fulfils all requirements.
