In the next SMACNA Duct Construction Standards (DCS) a new requirement will be implemented wherein all ductwork less than 3” water gauge utilize Class “A” sealing requirements, which means ALL TRANSVERSE (TDC & TDF) JOINTS AND LONGITUDINAL SEAMS (PITTSBURGH & SNAPLOCK) BE SEALED!
Be prepared and get ahead of this new standard with the Lockformer Cold Sealant System!
These portable cold sealant units (available in both 5-gallon and fixed 55-gallon sizes) should be factory installed to all Lockformer rollforming machines and are available with one to four gun systems.
Optical eye triggers are included to adjust flow. Snuffer devices are also included to eliminate leaks in the shut-off position. From pump assemblies to nozzles, everything is quality engineered for top performance.
The sealant itself is specially formulated to produce perfect, non-toxic, flame-retardant sealing beads to ductwork in-shop or on-site. Beads that won’t crust or shrink – even under extreme temperature conditions.
