VELAN 61
Purpose
Explosionproof traffic light is used for traffic control at the enterprises of oil and gas processing industry, chemical and pharmaceutical industry – at the enterprises with explosive gases IIA, IIB, IIC and flammable explosive dust.
Features
LED light source ensures low energy consumption for light traffic and long range of signal identification.
Modular system of traffic light ensures its simplicity and reliability.
Design
The traffic light consists of modules joined in single design. The module consists of explosionproof enclosure with “d” explosion protection, in which light source and thick-wall glass installed in enclosure cover are located. Above the glass on enclosure light filter is fixed determining color of light traffic module signal.
The traffic light has at least two cable glands. Visor installed on each light traffic module ensures increasing signal viewing distance. Grounding bolts are installed inside and outside.
