ITT’s new Bell & Gossett Primary-Secondary Header (PSH) is a combination air separator and manifold that creates independent primary and secondary circuits. Also known as a low-loss header, it includes a purge valve allowing users to easily remove any debris collected at the bottom of the vessel. The valve allows an air vent to release air trapped in the system. The PSH features brass air vents and drain valves and an epoxy resin-painted steel body in seven sizes. Its working pressure is 150 PSI with an operating temperature ranging from 32°F to upwards of 220°F.
