Hermetic and protective metal hatch

A new product from Paritet-K — a hermetically sealed protective metal hatch for shelters. The hatch is designed for use in shelters, bunkers, storage facilities, and as an emergency exit for technical premises, providing protection against blast waves and fire. The hatch withstands a blast load of 1 kgf/cm², with a calculated shock wave resistance of 100 kPa.

The total thickness of the hatch is 71 mm, with the protective layer filled with fire-resistant material. Tight closure is achieved by four mechanical levers that press the hatch against the frame and compress the rubber seal. Additionally, a thermo-expanding strip is applied around the perimeter, which seals the hatch in case of fire.

The hatch is reversible, meaning it can be installed either left- or right-handed. The clear opening size of the is 950 mm by 932 mm.
