Complete Packages to Purge, Quiet, Fill, and Service Your Hydronic System Out of the box, Watt's Boiler Header Module delivers components that make following the industry recommended near-boiler piping virtually foolproof. Boiler industry recommendations (system purge station, followed by an air separator, followed by a service fitting) ensure the contractor correctly pipes a hydronic installation — quickly, easily, and neatly in a compact job space.
AS-MBFL Air Separator - The AS-MB Air Separator employs rugged, corrosion-resistant coalescing media and a Duo Vent air vent assembly to provide microbubble air separation for a quieter heating system. The unit is fully serviceable in the field and comes in a flanged model designed to mate with the PIPF-T System Purge Station.
RBFF Service Fitting - Setting a new standard for fast and easy service calls, the RBFF Service Fitting
is connected below the AS-MB Air Separator. The RBFF employs a unique
3-way ball valve for isolation of the water pressure regulator and expansion tank
from system pressure. The RBFF Service Fitting’s drain port allows for unloading
pressure from the waterside of the expansion tank diaphragm for air charge
servicing and maintenance. Compared with traditional installations, the RBFF’s
one-piece construction eliminates up to 11 threaded joints.
3/4" NFT PIPF-T System Purge Station - During commissioning, by closing the Series PIPF-T’s ball valve and connecting
a hose to the purge fitting, an installer can push all of the initial air out of the
system. PIPF-T replaces up to seven fittings with a single compact unit.
