PENSUM Air: our flexible air-cooled chiller
Our PENSUM Air air-cooled chillers are designed for applications in the medium output range from 50 to 400 kilowatts. The series utilises the refrigerant R-454B, which has a GWP value of 466. The overall environmental assessment of a system depends on the specific application, system configuration and operating conditions.
Projects with our air-cooled PENSUM chillers
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
Free cooling uses ambient air temperatures to reduce compressor operation, cutting electricity consumption and thereby lowering operational CO₂ emissions compared to conventional mechanical cooling. 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. By combining cooling and heating in a single unit, the PENSUM Air Reversible Heat eliminates the need for a separate heating system, reducing primary energy demand and associated emissions compared to operating separate cooling and heating appliances.
All PENSUM Air models use the 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. R-454B has a GWP of 466, which is 78 % lower than the GWP of 2088 for R-410A. This reduces the climate impact attributable to the refrigerant charge over the product's service life compared to equivalent equipment using R-410A. The comparison relates solely to the refrigerant's global warming potential and does not represent an assessment of the product's overall environmental impact.
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.
