Explosion protection is very important for bulk solids handling. In order to protect processing plants against explosions caused by dust, gas or hybrid mixtures, measurement devices with the suitable ATEX approval are often used. DF rotary paddles have the necessary ATEX approvals for any explosive atmosphere.
