Discover sterile pressureless hatches

The range of aseptic pressureless hatches allows us to meet many requests from our customers. The main objective is to obtain a sterile pressureless hatch.

In collaboration with our customers, our design office has designed a watertight tank inspection hatch, washable in its entirety. The right angle of the industrial hatch frame allows to acquire enough pressure to ensure a sterilization of our product.

Suitable and secure manholes

Our range of no-pressure manholes ensures safety and Boyer quality. It allows the use of a manhole requiring no pressure. Our manholes are located at the top of a tank, allowing access to the contents without having atmospheric pressure.

Sealable manholes are used when making concrete tanks. They allow concrete to be poured all around the frame in order to have a perfect hold on the door. Sealing hatches are also used for any other concrete structure than tanks.
