ELEVEX is the effective solution of bulk material vertical transport explosion protection. ELEVEX reduces explosion pressure to an extremely low value, which means that even existing and used technologies can be safely protected in case of explosion completely without destructive effects. The list of factors that can cause an explosion in a bucket elevator or similar vertical transport system is long, and the probability the an explosion will occur during operation is high. Although use of this system does not prevent origination of an explosion in an elevator, the actual explosion effects can be brought to a minimum.
