Rotary Screw Compressors ASD Series With the world-renowned SIGMA PROFILE Flow rate 0.89 to 6.39 m³/min, Pressure 5.5 to 15 bar

ASD – Even more efficient Service-friendly design With its latest generation of ASD (ASD.4) series rotary screw compressors, KAESER KOMPRESSOREN once again pushes the boundaries of compressed air efficiency and availability. Not only do these optimised systems deliver more compressed air for less energy, they also combine simple operation and maintenance-friendliness with exceptional versatility and environmentally responsible design. Perfect partners The newly improved ASD systems save energy in a number of ways: equipped with further-refined SIGMA PROFILE rotors, the airends are controlled...

Uncompromising efficiency Save energy with the SIGMA PROFILE SIGMA CONTROL 2: Optimum efficiency At the heart of every ASD system lies a premium-quality airend featuring Kaeser’s SIGMA PROFILE rotors. Flowoptimised for impressive performance, these advanced rotors enable ASD systems to set new standards in terms of specific package input power. The internal SIGMA CONTROL 2 controller ensures efficient compressor control and monitoring at all times. The large display and RFID reader assure clear communication and maximum security. Variable interfaces enable seamless networking capability, whilst...

Premium compressed air quality with add-on dryer Power consumption (kW) ▀ Power consumption: KAESER add-on dryer ▀ Power consumption: refrigeration dryer with continuous control ▀ Energy savings: KAESER add-on dryer Energy-saving control Dependable KAESER centrifugal separator The integrated refrigeration dryer in ASD T units provides highly efficient performance, thanks to its energy-saving control. The dryer is therefore only activated when compressed air drying is actually required: as a result, the desired compressed air quality is achieved with maximum energy efficiency. A KAESER centrifugal...

Speed-controlled compressor with synchronous reluctance motor Precision pressure control The flow rate can be adjusted within the control range, according to pressure. Working pressure is kept constant to within ±0.1 bar. This allows maximum pressure to be reduced, thereby saving energy and costs. Durable and service-friendly: The rotors in the synchronous reluctance motor do not contain aluminium, copper or rare earth magnetic materials. This makes the bearings and rotors as easy to replace as those in asynchronous motors. The functional principle keeps heat losses in the motor to a minimum,...

Maximum efficiency with frequency-controlled synchronous reluctance motor Your benefits at a glance: Best system efficiency: IES2 as per EN 50598 Maximum energy efficiency throughout the control range Durable, service-friendly drive system Advanced drive technology Minimal operating costs, high productivity and availability High-efficiency synchronous reluctance motor High-performance frequency converter This range of motors combines the advantages of both asynchronous and synchronous motors, all within a single drive system. The rotors contain no aluminium, copper or rare earth magnetic materials....

Heat recovery system Ambient heat Total electrical power consumption Compressed air energy potential Approx. 5 % Heat dissipation from the drive motor Approx. 76 % Heat energy recoverable through fluid cooling Heat dissipated by the compressor into the ambient air Heat remaining in the compressed air Heat energy recoverable through compressed air cooling Heat recovery simply makes sense Space heating with hot exhaust air Amazingly, 100% of the electrical drive energy supplied to a compressor is converted into heat energy. Of that heat, up to 96% can be recovered and reused for heating purposes....

Heat recovery Energy-saving, versatile and flexible Required heating energy (%) PTG plate-type heat exchanger system Required heating energy throughout the year PTG plate-type heat exchangers consist of a package of pressed stainless steel plates. They combine excellent heat exchange characteristics with exceptionally compact design. PTG heat exchangers can be integrated into existing hot water supply systems and are suited for industrial applications. It goes without saying that heating is essential during the winter months. However, it is also needed to a greater or lesser extent at other times...
