Greenheck has added two new products to its automatic balancing damper (ABD) line. Model ABD-FD incorporates a UL 555 rated 1-1/2 or 3 hour static fire damper, flanged sleeve, an ABD and an optional factory-supplied grille. The entire ABD-FD assembly is UL rated and approved and can be used in both supply and exhaust applications. Ceiling radiation damper CRD-1WT, UL classified for wood truss floor/ceiling assemblies, now has the option to add an ABD mounted in the plenum box.
Pressure independent automatic balancing dampers are designed to maintain constant airflow volume in HVAC applications. The damper blade is calibrated to automatically adjust to changing pressures.
Greenheck, the worldwide leader in manufacturing and distributing air movement, conditioning and control equipment, offers the most UL certified dampers and the largest selection of AMCA licensed dampers in the industry.
