Additional Information
  • Robust stainless steel-aluminum cooler combination
  • Available with Sigma Frequency Control, variable speed control (VSD) for superior part load performance
  • All models available with i.HOC® integrated heat of compression dryer


Advantages
  • Heat-recovery made easy - Thanks to radial fans with high residual thrust, the heated exhaust air can easily be ducted away and used for heating an adjacent room without additional auxiliary fans.
  • Energy-efficient features - In standby mode, the temperature-controlled Kaeser standstill fan reliably dissipates residual heat. This allows the main fan to turn off and cools the package down for quicker service.
  • Exceptionally maintenance-friendly - Swing-out coolers make cleaning easy.


Low Life Cycle Costs
Our custom consulting services, award-winning product design, and continual investment in our research and development give you superior quality that's tailored for your needs.

Quality in Detail

Hydraulic Inlet Valve
The hydraulic inlet valves in Kaeser's oil-free rotary screw compressors are unaffected by contamination and condensate. This makes them more reliable and easier to maintain than pneumatic valves.

Fiber-Free Pulsation Dampeners
Kaeser's new fiber-free pulsation dampeners keep pressure losses to an absolute minimum, help maintain consistent air quality and, unlike fiber versions, eliminate the possibility of compressed air contamination.

Reliable Oil Reservoir Venting
The microfilter in the oil tank venting system prevents the intake of oil-laden air. This ensures compressed air quality is maintained at all times.

Highly Efficient Condensate Separator
Thanks to its flow-optimized design, the newly developed condensate separator reliably separates the condensate downstream from the air coolers, and with minimal pressure loss.


Adsorption

Bolt-Down Machine Mounts
Machine mounts for bolting the unit to the floor


Options

Silencer for Air Inlet Opening
Dampening louvers in front of heat exchangers

Cooling Air Filter Mats
  • Cooling air filter mats in the inlet area of the compressor
  • Reduce build-up on heat exchanger surfaces and inlet air filters

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 required hot air temperature can be controlled in ranges.
