Explosionproof LED lighting fixture VELAN37

Purpose

Lighting fixture is used at the enterprises of oil refining, chemical and pharmaceuticals industry and other enterprises, where occurrence of explosive gases IIA, IIB, IIC and flammable explosive dust, as well as in places being gas hazardous (methane containing mixtures), coal dust is possible. It is intended for lighting within explosion hazardous areas of coal minings and other places according to explosion protection marking.

Features

• Design reliability.
• Large luminous flux at small overall dimensions.
• The possibility to use lighting fixture for general lighting.
• The possibility of transit connection.
• The possibility of modular replenishment (combining up to three modules in one lighting fixture).

Design

Lighting fixture VELAN37 consists of body and cover made of Zamak or aluminum alloy for РВ ExdsI version or aluminum alloy for 1ExdsIICT6 version. Lighting fixture coating is enamel. Under dome form organic transparent glass LED panel filled with optical compound is installed. One cable gland and one plug are installed in lighting fixture. Inside lighting fixture body power driver for LEDs and terminal clamps are installed.
