Water-cooled

Durable yet refined drive and cooling solutions enable us to achieve lowest possible power consumption values. This, in combination with a Kaeser heat recovery system, also allows you to significantly reduce your heating costs. We’d be glad to help you with a solution that meets your exact needs.
Thanks to their compact design and type-dependant small exhaust air duct, our water-cooled oil-free compression rotary screw compressors earn extra points when it comes to installation in low-ceiling areas.
* Flow rates from 3.3 to 50.8 m³/min
* Also available as a peak-load model with variable-speed control and frequency converter (SFC model versions)
* Also available with integrated i.HOC rotation dryer (DSG-2 series)

Your advantages

Extraordinarily low compressed air discharge temperature:
The tube bundle of the two air/water heat exchangers consists of high-quality CuNi10Fe pipes with welded-on aluminium star profile for optimal heat conduction.

Lower costs thanks to heat recovery:
With a Kaeser heat recovery system, up to 96% of compres

Maintenance-friendly:
The air/water heat exchangers of the 1st and 2nd compression stages are housed in two separate enclosures, each with optimal accessibility thanks to large service doors.

Hydraulic inlet valve
The hydraulically operated inlet valves in Kaeser oil-free compression rotary screw compressors are unaffected by contamination and condensate. This makes them more reliable and easier to maintain than pneumatic valves.
Fibre-free pulse dampers
Kaeser’s new fibre-free pulse dampers keep pressure losses to an absolute minimum, help maintain consistent air quality and, unlike fibre versions, do not present a source of contamination for the compressed air.
Reliable oil reservoir venting
The microfilter in the oil tank venting system prevents the intake of oil-laden air – a key detail to ensure that compressed air quality is reliably maintained at all times.
Highly efficient condensate separator
Thanks to its flow-optimised design, the newly developed condensate separator reliably separates the condensate downstream from the air coolers, with minimal pressure loss.

Bolt-down machine mounts
* Machine mounts to bolt the machine to the floor

Heat recovery
* Integrated heat exchanger system comprising parallel switched tube-type heat exchanger, heat exchanger (water/water), pump, expansion valve and water control valves

Hot air connection
* Direct use of the hot compressed air, e.g. for heat regenerating desiccant dryer or as hot process air.
* With certain models, the desired hot air temperature can be controlled in ranges.
