Advantages

Advantages

 N/A
  • 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.

Quality in Detail

Hydraulic Inlet Valve

 N/A 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

 N/A 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

 N/A 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

 N/A 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.

Options

Bolt-Down Machine Mounts

 N/A Machine mounts for bolting the unit to the floor

Silencer for Air Inlet Opening

 N/A Dampening louvers in front of heat exchangers

Cooling Air Filter Mats

 N/A
  • 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

 N/A
  • 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.
