Pressureless aseptic hatches
Our pressureless aseptic hatches provide you with high quality. Aseptic hatches are mainly used at the top level of the tank allowing easy and safe access to the inside of the tank.
Our industrial hatches guarantee you compliance with manhole passage regulations while certifying 100 years of quality experience from Boyer. Quality, safety and innovation are the key words of our design office.






Sterile industrial trap door
The right angle of the industrial no-pressure trap door frame provides sufficient hold to ensure the sterilization of our products.
The primary purpose of an aseptic no-pressure trap door is to prevent any microorganisms or bacteria from interfering with the contents of the container.

Simplified tank maintenance
These categories of hatches are mainly positioned at the top level of the tank due to their lack of pressure resistance.
However, they are used a lot due to their ease of use and thanks to the possibility of completely removing the door's gate. The maintenance of your tank will then be simple and fast.
