Additional Information

Their compact design and model-specific sized exhaust make them ideal for installations with low ceilings.

All models available with i.HOC® integrated heat of compression dryer

Advantages

Low compressed air discharge temperature - Cupronickel (CuNi10Fe) cooling pipes with internal star lamella fins provide optimum heat transfer.
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 195 ºF.
Maintenance-friendly - The air/water heat exchangers of the low and high pressure stages are housed in separate enclosures, each with large service doors for easy maintenance accessibility.

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

Heat Recovery		Integrated heat exchanger system including parallel shell and tube heat exchangers, 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 required 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 90ºC. This makes it possible to achieve an amortization period of less than a year.

Hot Water Up to +90 Degree Celsius (ºC)		Recovered heat energy can be used in any number of ways. Heat recovery provides warm water up to 90 ºC as appropriate for specific applications.

Heat Recovery a Win		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		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.
