| Sigma Control 2 |
|
|||||||||
| 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. | |||||||||
| Bolt-Down Machine Mounts | Machine mounts for bolting the unit to the floor | |||||||||
| 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 |
|
|||||||||
| 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 ºC. 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. | |||||||||
