Our Blow-off vessels are manufactured in accordance to the latest ASME Section VIII Div. 1 Code. Vessels are “U” stamped and registered with the authority having jurisdiction or with the National Board of Boiler and Pressure Vessel Inspectors.
Blow-off from any boiler having a pressure exceeding 15 PSI (103 KPA) and discharged into a sewer requires the use of a registered blow-off vessel placed between the boiler and sewer to insure a maximum discharge temperature of 150۫ F (65۫ C). Each Clemmer blow-off vessel is designed and registered for use with either a conventional or coil tube boiler, has a maximum working pressure of 100 PSI (690 KPA) and is fabricated from a minimum plate thickness of 3/8″ (9.5mm) and in accordance with ASME Code Section VIII Division 1. All Clemmer Blow-off tanks have facilities for internal inspection, connections for drain, inlet, outlet with an anti-siphon device, vent, cold water inlet and pressure gauge.
