Oil-free compression rotary screw compressors with water-cooling


Compact energy-savers

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 compressor exhaust heat can be recycled – for example, to heat water to 90 °C.
  • 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.
Life-cycle costs

Optimal consulting, technically advanced research and development and a global service organisation protect you from system failures.

Quality in detail

Hydraulic inlet valve

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

Fibre-free pulse damper

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

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

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.

Options

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.
Maximum savings with energy recovery

Efficient and convenient use of recyclable compressor heat

With an integrated heat recovery module, recyclable compressor heat can be used for hot air space or process heating, as well as for heating of service or process water to temperatures up to 90 °C. This makes it possible to achieve an amortisation period of less than a year.

Hot water up to +90 °C

Hot water from heat recovery up to +90°C

Recovered heat energy can be used in any number of ways. Heat recovery provides warm water up to 90 °C as appropriate for specific applications.

Heat recovery a win

Maximum heat recovery with rotary screw compressors.

Amazingly, 100 percent of the electrical energy input to a compressor is converted into heat. Of this, up to 96 percent is available for heat recovery purposes.

Maximum availability despite heat recovery

Maximum availability with optional internal water circulation loop.

During maintenance work on the water system of the heat recovery system other than the compressor, an optionally available complete internal water circuit (with pump, expansion valve, safety valve, etc.) ensures reliable compressor performance.

Reliable heat recovery for your application

For self-protection purposes, compressors with integrated heat recovery are equipped with a secondary water system. This separation into a primary and secondary water system not only ensures reliable compressed air supply availability with optimum heat recovery performance, but also provides the flexibility of coupling or decoupling the oil and jacket cooling to / from the heat recovery system according to required heating demand.
