Halton’s WTH effectively prevents rainwater, snow, leaves, animals and other objects from entering into ductwork. Halton’s Weather Tight Hatch can be used as a cover for droplet separators and outdoor louvres. WTH is designed for demanding applications such as marine, oil & gas, chemical and energy industries where reliability and ease of installation play an important role. The hatch is used to shut down the ventilation openings in applications close to the waterline and even on rough seas.

WTH hatches are manufactured for rectangular openings (width B 100-1200 mm and height H 100-1200 mm, with 1 mm division). Modular construction for larger sizes is available. Cover thickness (C) is minimum 34 mm, but is variable by material thickness.
