Blowdown Separator with Vent Head and Cooling Valve

The Model BDS, Boiler Blowdown Separator is a manufactured unit used for after-cooling of boiler blowdown or condensate before discharge to Sanitary Sewer. The BDS is ideally suited for reducing wastewater temperature of continuous blowdown discharge to municipal sewers. Atmospherically vented, the Model BDS is a complete unit including a Carbon Steel Separator, a Make-up Water Capillary-style Temperature Control Valve, and Vent Head. Each Unit is custom engineered and designed to meet specific system requirements. All systems are fabricated and welded per ASME Section IX Code and Standards, and are Hydrostatically tested prior to shipment.
