Kaeser redesigns CSD series screw compressors

CSD series compressors from Kaeser Compressors Inc., Fredericksburg, Virginia, have been redesigned and now feature five models from 60 to 125 horsepower. They offer significantly improved efficiency over a wider range of flows and pressures, according to the manufacturer, with capacities ranging from 261 to 693 cubic feet per minute at pressures ranging from 80 to 217 pounds per square gauge, or psig.

With new airend designs and IE4 Super Premium Efficiency motors, Kaeser says its CSD compressors have even better specific performance and deliver up to 25 percent more air than competitive models. 

The company’s standard Sigma Control 2 includes external communication capabilities and data storage for better asset and energy management. Routine maintenance is easier with an open package layout, oversized access doors and convenient placement of fluid level indicator and fill port, Kaeser says.

Standard features also include a frequency-controlled fan with a brushless DC motor and an eco-friendly fluid filter element. All five models are available with integrated refrigerated dryers and Eco-Drains.
