BH250B Exs II T4 Aluminum Air Driven 4.0-8.0 Bar Halogen Beam 24V 250W Explosion Proof Pendant Light


The product could work under the ambient temperature from -20℃ to +50℃ , It is apply to explosion gas area(Zone 1 and Zone 2)and explosion dust area(Zone 21 and Zone 22 ), apply to gas ares of IIA、IIB、IIC class.Temperature classification is from T1 to T6.


Due to its special construction, the lighting of dangerous atmospheres inside and outside the lamp is avoided through several solutions. First, air flows into the lamp housing and creates overpressure before it flows into the generator housing. If the lampshade or the protective glass is damaged, and the air flows out first. The generator stopped immediately and could not cause any flame in the bulb. The exhaust air prevents the penetration of explosive gases in the lamp and also cools the screw of the broken bulb.


The lamp housing is made of brass or aluminum.
