50 HP Rotary Screw Air Compressors

Kaeser's 50 HP Screw Compressor Models

Standard 50 HP Air Compressor

Kaeser's 50 hp rotary screw compressors with direct drive incorporate all standard Kaeser features, such as powder-coated enclosures, premium efficiency TEFC motors, and the SIGMA PROFILE airend. These units are available with integrated dryers and/or variable speed drive options.

50 HP Air Compressors with Integrated Dryers

BSD 50T - 50 hp screw compressor with dryer

The BSD 50T is a rotary screw compressor with integrated refrigerated dryer 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.

50HP Rotary Screw Compressor with Variable Speed Drive

SFC 37 - 50 hp screw compressor with variable speed drive

The SFC 37 50hp rotary screw compressor is the perfect solution for smaller compressed air systems with varying air demand to achieve significant energy savings while maintaining stable pressure. KAESER SFC units are up to 25% more efficient than the competition. These units are available with an integrated dryer. Learn more about Kaeser's SFC series of compressors with variable speed drive.

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.
