Kaeser’s new DHS air main charging valve.

Removal of moisture, particulates and hydrocarbons from a compressed air system is vital in order to protect pneumatic equipment, minimize downtime, and reduce scrap and inferior product. As an electronically controlled intermediate control, the DHS unit acts on a pressure signal to prevent high velocity conditions that will occur when system pressure is low. This maximizes contact time in air treatment components and makes them more effective. It also increases the bead and filter life of desiccant dryers by reducing dusting in the desiccant bed.

DHS units feature high visibility LED indicators to communicate status at a glance. They can also be wired to dryers and drains and will close to prevent contamination from getting downstream in case of a failure, or shutdown. Users interested in remote monitoring/control can connect the DHS unit to plant monitoring systems, or an existing Kaeser Sigma Air Manager 4.0.

DHS models are available in eight sizes from 1-inch ball to 8-inch butterfly valves to accommodate nearly any system. For more information, visit
