Dust space heater Type DRHA0/ST (RH5)

Design: Ex space heater with closed enclosure made of carbon steel, painted, to avoid deposits of dust on the hot surface. Self-limiting ceramic heating inset with explosion proof connection box, made of cats iron, painted. The surface temperature of the space heater is limited to 120°C. The maximum admissible surface temperature in dust Ex areas is 2/3 of the minimal ignition temperature of the dust (180°C for the most critical case). The built-on Ex temperature regulator type QTREK 0...100°C serves for additional control of the surface temperature, e.g. for personal protection. Also the room temperature can be controlled indirectly.
