Kaeser's 7.5 HP Screw Compressor Models

Standard 7.5 HP Air Compressor

Kaeser's standard 7.5 hp screw compressor models in the SX and SM series offer impressive performance and quiet operation. They feature a robust design with super-silenced, vibration-dampening, and powder-coated panels, suitable for ambient temperatures up to +115 °F. The units are equipped with an IE3 premium efficiency motor (IP 54) and an innovative dual-flow fan with separate airflow channels for efficient cooling of the motor, fluid/compressed air cooler, and control cabinet. Key fluid and airflow features include a 'Honeycomb' air intake filter, pneumatic inlet and venting valves, a triple-separation system in the cooling fluid separator tank, and comprehensive pressure and fluid management components.

7.5 HP Air Compressors with Integrated Dryers

SX7.5T - 7.5 hp screw compressor with dryer

The SX 7.5T and SM 7.5T 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.
