Standard 175 HP Air Compressor

DSD 175 - 175 hp screw compressor

Kaeser's 175 hp rotary screw compressors in the DSD series 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.

175 HP Air Compressors with Integrated Dryers

DSD 175T - 175 hp screw compressor with dryer

The DSD 175T is a rotary screw compressor 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.

175HP Rotary Screw Compressor with Variable Speed Drive

SFC 132S - 175 hp screw compressor with variable speed drive

The SFC 132S 175 hp rotary screw compressors with variable speed drive are the perfect solution for 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.

Why Choose a KAESER 175 HP Rotary Screw Compressor?

Kaeser's 175-hp rotary screw air compressors provide outstanding efficiency and reliability. Featuring an energy-saving SIGMA PROFILE airend and a SIGMA CONTROL 2 controller, these compressors are designed to meet and exceed our customers' expectations, outperforming and outlasting other compressor solutions on the market.

Service-Friendly Compressor Design

Kaeser Compressors designs rotary screw compressors with the user in mind. Fewer wearing materials and using premium quality materials ensure reduced maintenance requirements, longer service intervals, and extended service life. Our DSD rotary screw compressors feature an open package layout. All of the major components are easily accessible, reducing preventive maintenance time by as much as 50% when compared to other similarly sized screw compressor units. Lockable panels provide easy access to all maintenance items. Electrical components are housed in a spacious, ventilated control cabinet. Wiring is neatly arranged and terminals are clearly identified. When you consider the maintenance costs savings, it’s clear that owning a Built for a lifetime™ Kaeser compressor will save you money, year after year.

Guaranteed Efficiency

At KAESER our rotary screw compressors are designed with maximum efficiency in mind. Every component in a Kaeser rotary screw air compressor system is carefully designed with performance in mind. Unique components such as our patent-pending double-flow cooling fan increases air flow while reducing overall power requirements and the proprietary Sigma Profile airend is optimized for low airend speeds required from 175hp compressors. In fact, our DSD series 175 horsepower compressors are up to 30% more efficient than the competition guaranteeing lower operating costs regardless of your compressed air application.

Rugged Reliability

Kaeser’s screw compressors meet our rigorous “built for a lifetime” standard. Designed and built with Kaeser’s generations of compressed air experience, you can rest assured that these compressors will continue to deliver the air you need with the exceptional reliability you expect from a Kaeser compressor. Our 175 hp rotary screw compressors are equipped with high efficiency coolers ensuring reliable compressor operation in any environment. Filter mats simplify maintenance needs by capturing particle build up on the outside of the filter where it is easily seen and removed. This reduces the frequency of cooler servicing needs and ensures your compressor can operate in dust and dirt heavy environments. Due to their enclosure system, Kaeser’s totally enclosed, fan cooled (TEFC) motors used in our 175 HP air compressors are also less susceptible to dirt and dust than commonly used open drip proof (ODP) motors.
