Explosion Protection

The device category 2 („2G“) as seen on the product label on TA-Roloff‘s products always requires proven design testing according to the so called ATEX guidelines and is confirmed by recognized certification bodies such as IBExU and DEMKO).  In addition to this we undergo yearly inspections and audits from these organisations. The explosion certification for your plants will therefore be achieved without any difficulty by using TA Ex products.  

Manufacturers’ declarations which suffice for device category 3 (“3G”) and bearing the “Ex” label are only as good as the manufacturers themselves. Actuators from Category 3G may only be used when explosive conditions can arise “rarely and for short periods of time”. Do not buy into such dangerous and precarious scenarios. Opt instead for TA Roloff’s tested, safe and appropriate actuator technology.
