EXH Explosion-proof housings

– Solid anticorodal aluminum construction

– Epoxypolyester powder painting, RAL7032

– IP66

– Certification ATEX, IECEx, GOST-R e CNEX

The EXH housings are made with strong Anticorodal aluminum die-cast alloy of AISi Mg EN AB- 42000 group. Depending on the model, all external components are stove enameled using powder or with special coatings offering an excellent resistance to UV rays, salt-spray, environment polluting substances (mod. 003R, mod. 005R). They are constructed according to the 94/9/CE ATEX standard, IEC 60079-0: 2007, IEC 60079-1: 2007, IEC 60079-31: 2008, GOST-R standard and the Chinese standards.

EXHC

The cylindrical body of EXHC housing (diameter 210mm and length 400mm) is closed on the opposite sides by two 12mm thick flanges. The housing is supplied with two holes for the 3/4″ NPT cable glands. The camera housing is equipped with heater and optional sunshield.

EXHD

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.

The glass protection device consists of a connection flange with the housing, a closing flange and an explosion-proof central body containing a rugged and transparent glass, a motor powered in 24Vac, two windings 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 product.

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.
