The Q-Box captures flames and heat during explosion venting; allowing easy indoor and outdoor installation and positioning of relevant machinery. Manufacturing equipment of low sturdiness and with large venting area requirements is cost-effectively protected from the aftermath of an explosion. The rectangular cross section complements the dimensions of standard explosion vents, making the protection system suitable for retrofitting existing installations. This protection system is maintenance-free, negating operational costs. The Q-Box is the perfect safety system for indoor devices, such as elevators, and when compared to cost-intensive venting ducts, the Q-Box is the true economical alternative.
