Kaeser is known for its high-quality, durable compressor blocks with the efficient Sigma profile. These are now also installed in the CSG series. The rotors have a coating that is particularly wear and temperature resistant. A biocompatible and FDA-certified PEEK coating meets the requirements of the pharmaceutical and food industries.
High energy efficiency achieved
The series is equipped with synchronous reluctance motors of energy efficiency class IE5 (ultra premium efficiency). A highly effective water jacket cooling system is used on both compressor stages. The fiber-free pulsation dampers have a broadband effect and very low pressure loss. These and other optimization measures ensure that the compressor is highly energy efficient. The CSG series delivers 16 percent more volume flow with the same rated motor power. The maximum operating pressure has been increased from 10 to 11 bar.
Clever use of compressor waste heat
Another key aspect of product development was to make it easy for the customer to utilize the compressor waste heat in order to reduce the CO2 footprint. Kaeser therefore offers the integrated i.HOC adsorption dryer for air- and water-cooled systems. This cleverly uses the compressor waste heat to regenerate the desiccant with minimal energy consumption and achieves safe and stable oil-free compressed air with pressure dew points down to minus 30 degrees C even under difficult ambient conditions.
