KCH fabricates an array of hood styles including up right, downdraft, side lateral, and canopy. KCH Services manufactures a wide assortment of exhaust hoods for capture of toxic containments local sources. PVC, CPVC, PP, Dual Laminate, and FRP materials are used for construction depending upon each specific application. Hood lengths can vary from as little as 12" to 40' long. All KCH exhaust hoods are fabricated of Type I or Type II, Grade 1, high impact PVC, polypropylene or FRP. The basic hood shape is fabricated of .1875" (3/16) thick PVC and hot welded. For additional strength and reliability, joints are welded both inside and outside wherever possible and corners along the length of the hood are heat formed. Slot dividers on vertical type hoods are internally reinforced using .25" (1.4) thick PVC sheet, angle spaced not greater than 12" and all lip type hoods have top and bottom slot section reinforced with .25" (1/4) PVC.To prevent warping, additional PVC reinforcing is used as required to strengthen the hood at critical points. All KCH hoods are equipped with a means of preventing liquid from accumulating in the bottom. Hoods having a plenum lower than the lowest slot have a drain crease in the bottom with a 1" threaded coupling.
