ASD Series
The ASD Series is the ideal compressed air solution for AEP customers looking for maximum compressed air efficiency. The innovative design ensures that these compressors deliver more compressed air for less energy, saving you money. Easy to use and maintain, these rotary screw compressors are versatile and suitable for many requirements.
Key benefits of the ASD Series include:
- Energy and money savings - The intelligent design of the ASD systems saves energy in various ways: the compressor airends feature further refined SIGMA PROFILE rotors, which are controlled and monitored via the industrial-PC-based SIGMA CONTROL 2 compressor controller. This advanced controller matches compressed air delivery to actual demand and uses dynamic control to keep wasted time and energy to an absolute minimum.
- Perfect Match - ASD series rotary screw compressors are the perfect match for high-efficiency industrial compressed air stations. The internal SIGMA CONTROL 2 compressor controller offers multiple communication channels, which allows seamless communication with advanced master controllers, such as KAESER’s SIGMA AIR MANAGER, and in-house centralised control systems. This ensures easy setup and performs at ultimate levels of efficiency.
- Changing speed with reluctance motor - Enjoy the advantages of asynchronous and synchronous motors in one drive system, with the new synchronous reluctance motor. Containing no aluminium, copper, or expensive rare earth magnets, the drive is durable and service-friendly. Additionally, heat losses in the motor are kept to a minimum which results in significantly lower bearing temperatures. This assures substantially extended bearing and motor service life. Compared with an asynchronous motor, the synchronous reluctance motor with the perfectly matched frequency converter delivers exceptional performance in terms of losses, especially in the partial load range.
- Electronic Thermo Management (ETM) - The sensor-controlled temperature control valve integrated into the cooling circuit is the heart of the innovative ETM system, which is powered by an electric motor. To prevent condensate formation, the new SIGMA CONTROL 2 compressor controller monitors intake and compressor temperature, even with differing air humidity conditions. The ETM dynamically controls fluid temperature – low fluid temperature enhances energy efficiency. This compressed air system also allows end-users to use heat recovery systems to suit their specific requirements, by adapting to their needs.

ASD T Series - Premium compressed air quality with an add-on refrigeration dryer
Energy-saving control
The integrated refrigeration dryer in ASD-T units provides high-efficiency performance thanks to its energy-saving control. The dryer is only active when compressed air needs to be dried; this achieves the required compressed air quality with maximum efficiency.
Dependable KAESER separator
A KAESER centrifugal separator fitted with an electronic ECO-DRAIN condensate drain installed upstream from the refrigeration dryer ensures that condensate is reliably pre-separated and drained, even when ambient temperatures and humidity are high.
Refrigeration dryer & ECO-DRAIN
The advanced level-controlled condensate drain eliminates the compressed air losses associated with solenoid valve control, thereby saving energy and considerably enhancing operational dependability.
Minimal refrigerant requirement
The refrigeration dryers in the new ASD-T units require approximately 36% less refrigerant than previous generation dryers. This not only saves costs but is also significantly more environmentally friendly.

ASD (T) SFC Series - Speed-controlled and maximum efficiency
Precision pressure control
The flow rate can be adjusted within the control range according to pressure. Operating pressure is kept constant to within ±0.1 bar. This allows maximum pressure to be reduced, which, in turn, leads to significant energy and money savings.
Durable and service-friendly
The rotors of the synchronous reluctance motor do not contain aluminium, copper, or magnetic materials using rare earth metals. This keeps heat losses to a minimum, resulting in lower bearing temperatures. This ensures extended bearing and motor service life.
Separate SFC cabinet
The SFC variable speed drive is housed in its own control cabinet to shield it from heat from the compressor. A separate fan keeps operating temperatures in the optimum range to ensure maximum performance and service life.
Entire system EMC-certified
It goes without saying that the SFC control cabinet and SIGMA CONTROL 2 are tested and certified both as individual components and as a complete system to EMC directive EN 55011 for Class A1 industrial power supplies.
