Type DSS-GNU condensate unit is designed for reverse osmosis (RO), deionized (DI) and clean steam applications where you need 100% stainless steel interior material touching liquid. The unit is equipped with specially designed, 100% interior stainless steel float switches and mechanical alternators with stainless parts and bushings. Therefore everything coming in contact with liquid is stainless steel.
DSS-GNU uses a patented design GNU pump which handles up to 200°F condensate and is made with a rectangular 300 series stainless steel receiver. Unit has an 8-1/2" or 8-3/4" inlet height from floor to centerline for all sizes and models to help with extremely low inlet situations. The top mounted, close-coupled pump is 316L stainless steel and utilizes a propeller shaft with its high temperature patented bearing design (U.S. patent #4,932,846). DSS-GNU is available in simplex or duplex configurations with a variety of options and accessories including a special all interior and exterior stainless steel option. These units eliminate the need for pump isolation valves since the pump is mounted on top of the receiver. As an added advantage these units can fit into a smaller floor space area than conventional Type DS or Type PS units. The standard mechanical seals are for 250°F and higher temperature seals and special faces are available upon request.
