Kaeser's 25 HP Screw Compressor Models

Standard 25 HP Air Compressor

AS 25 - 25 hp screw compressor

Kaeser's 25 hp rotary screw compressor offerings include both v-belt drive (AS 25) and direct drive (ASD 25) standard models. Both the v-belt drive and direct drive base models incorporate all standard Kaeser features, such as powder-coated enclosures, premium efficiency TEFC motors, and the SIGMA PROFILE airend. Additionally, both designs are available with integrated dryers and/or variable speed drive options.

25 HP Air Compressors with Integrated Dryers

ASD 25T - 25 hp screw compressor

The AS 25T and ASD 25T are rotary screw compressors with integrated refrigerated dryers sized for the full flow of the compressor. The dryer is located in a separate cabinet so it is not exposed to preheated air or contaminants from the compressor package.

Energy-Saving Control:

The integrated refrigerated dryer in "T” units provides high efficiency performance thanks to its energy saving control. The dryer is active only when compressed air actually needs to be dried. This approach achieves the required compressed air quality with maximum efficiency.

Eco-Drain:

The integrated refrigerated dryer also features a zero loss Eco-Drain. The advanced level-controlled condensate drain eliminates the compressed air losses associated with solenoid valve control. This saves energy and considerably enhances the reliability of the compressed air supply.

Climate-Friendly Design:

In addition to energy-saving controls, our integrated dryers feature the new R-513A refrigerant with 56% lower global warming potential than common dryer refrigerants. Combined with our advanced heat exchanger design, we need only half the refrigerant — resulting in the most climate-friendly dryer possible.

 
 

25HP Rotary Screw Compressor with Variable Speed Drive

SFC 18 - 25 hp screw compressor with variable speed drive

The SFC 18S and SFC 18 25-hp rotary screw compressors are the perfect solution for smaller compressed air systems with varying air demand to achieve significant energy savings while maintaining stable pressure. These SFC units are up to 18% to 25% more efficient than the competition. Both units are available with an integrated dryer. Learn more about Kaeser's SFC series of compressors with variable speed drive.

power consumption vs flow rate

A variable speed screw compressor should be the most frequently loaded unit in a properly designed system. Each is optimized to deliver significantly more air with lower kW than comparable compressors.
