Integrated dryer option DSD 125 - 175 models are available with an integrated dryer for premium compressed air quality. The dryer is perfectly sized for the full flow of the compressor and located in a separate cabinet so it is not exposed to preheated air or contaminants from the compressor package. Reduced footprint Intelligent cooling air flow The refrigerated dryer’s cooling air is warmed by the integrated exhaust air duct located in the roof of the compressor package. This allows for a significantly reduced depth for the integrated dryer. In keeping with Kaeser’s design philosophy,...
