EXHC003R Videotec Explosion Proof Housing w/ Triple Heater and Glass Protection Device 24VAC

Explosion-proof housing with the same specifications as the EXHC series but fitted with a patented device for the protection of the glass which gives clear vision in dirty environments. It consists of a connection flange with the housing, a closing flange and an explosion-proof central body containing a rugged transparent glass, a continuous current motor powered in 24Vac, two rollers and a transparent Mylar film, installed just in front of the glass. The motor drives, through four pinions with gear  rim, the winding for recovering the dirty Mylar film, while at the same time the other winding installed on the opposite side releases the clean film.

NOTE: the control unit of the glass protection device is not supplied with the EXHD.

The transparent Mylar film, 80mm wide and 18m long, allows 350 steps. When the film is dirty, the operator will activate the motor shifting the film to obtain a clean camera picture (the step for allowing the complete shift of the dirty film is about 50mm). The end of the Mylar film will be indicated to the operator through marks printed on the last 50cm of the film.
