For us, a compressed air supply using rotary screw compressors represents the centrepiece of your production process. Our ASD, BSD, CSD and CSD(X) series ensure a dependable compressed air supply for your processes with unprecedented levels of efficiency. 

These systems are perfect team players that can be integrated into existing control systems via the SIGMA AIR MANAGER 4.0. To ensure that you achieve the exact compressed air supply you require, our rotary screw compressors are available in different variants:

Base model
with refrigeration dryer for high compressed air quality: T model
with variable-speed drive for optimum efficiency and a broad control range: SFC model
with synchronous reluctance motor: Significantly greater efficiency – especially in the partial load range – than comparable asynchronous systems enables considerable energy savings.
Complete systems with integrated refrigeration dryer and variable-speed drive: T SFC models 
Our experts will be glad to assist you in selecting the right model for your needs.
Your benefits

Energy savings:
Fixed-speed systems with asynchronous motors which meet the IE4 efficiency class. Frequency-controlled rotary screw compressors are equipped with IE5 motors and meet the IES2 system efficiency class.
Longer service life:
Electronic Thermo Management dynamically controls the fluid temperature on compressors from the ASD, BSD, CSD and CSD(X) series. This not only saves additional energy, but also reliably prevents condensate formation and the associated moisture damage.
Heat recovery:
Our rotary screw compressors convert 100% of the electrical drive energy supplied to them into heat energy. 96% of this energy remains available for heat recovery. Use this potential to your advantage!
