If gases and dusts explode in plants, pressure relief devices protect the plant from the destructive forces caused by these events. For many years, containers and plant components in the chemical, pharmaceutical and food industries, as well as in woodworking and wood processing, have been equipped with the Q-Box for this purpose. In contrast to conventional systems such as rupture discs, the pressure relief device does not release any flames into the environment, thus minimising the risk of fire.
The device is based on a special, closed pressure relief system. In the event of overpressure in the system, the hot combustion gases resulting from an explosion are channelled into the Q-Box. There they are expanded and cooled in a special filter medium before being safely released into the environment. In this way, the Q-Box also protects system components with a low pressure shock resistance via its large pressure relief surfaces. Compared to other pressure relief systems, the Q-Box is an economical option because no complex blow-off ducts need to be installed and there are no external maintenance costs.
