Appointment
Explosion-proof lamps for gas-discharge lamps are intended for the general lighting of fields, sea platforms, docks and plants in which emergence of explosive gases or dust, according to explosion protection marking is possible.
Features
-
Allows installation of all types of gas-discharge lamps with power from 70 to 400 W. Feature of lamps is that PRA is already established in the lamp and does not need the additional order.
-
The extra-strong plafond with high transparency bears blow of 4 J at a temperature of -60 °C and allows hit of a cold stream of water on the working lamp without loss of strength characteristics.
-
Corrosion-resistant materials with a special covering provide long service life.
-
Possibility of a complete set of the lamp dome-shaped reflector.
-
Three dimensions of the case depending on the power of the used lamps.
Light sources
-
mercury lamp of a high pressure like DRL (RT.L.)
-
sodium lamp of a high pressure like DNAT (NAT.L.)
-
metalhalogen lamp like DRI (GAL.L.)
