Access doors to environmental simulation chambers can be very dangerous and cause serious damage

Access flaps or doors must seal the chamber hermetically from the exterior, otherwise it is not possible to carry out any meaningful tests. This is why the doors of large simulation chambers sometimes weigh hundreds of kilos. And, especially in outdoor areas, they are exposed to wind and harsh weather.

Some of the doors weigh hundreds of kilos

If such heavy doors are thrown open – either accidentally by hand or by the wind – it can be very dangerous for people who are next to the door. But the environmental simulation chamber could also be affected, as the door may no longer close hermetically because it may have deformed on impact. Or the equipment in the doors may no longer function correctly. Another risk is that the exterior shell of the chambers may be damaged. In addition to the risk to the safety of people, such an uncontrolled door opening can lead to a prolonged breakdown of the chamber, which could cause major problems for the facility operator.

Back check prevents uncontrolled opening or impact even on extremely heavy doors

The solution is very simple. Weiss Technik fitted back checks on each of the two large door leaves and to the doors for pedestrian access. They prevent them from opening and closing too quickly. Of course, DICTATOR also provided support with the calculation of the correct back check and the fixing points so that the installation could be carried out quickly and without any problems.
