Explosion proof Pilot Light Indicator for Zone 1 and 21

Explosion proof Pilot Light Indicator for Zone 1 and 21

Pilot lights, also referred to as power indicator lights are used in machine and industrial process units to indicate the start and stop of functioning. The indicator in the pilot light changes the color of illumination from red to green, signifying stop to start or by flashing or blinking the light to indicate an emergency.

The lights are placed on a machine or an easy-to-access control panel to be operated easily. It is also used in hazardous areas and needs to be specially made with materials that can withstand the harmful elements.

We have been manufacturing and distributing high-quality pilot lights for various industries that work in hazardous environments. Our products for the hazardous areas have a high IP rating, making them safe to use in such areas.

Our Exde operator pilot light is used in chemical and petrochemical plants, oil and coal refineries offshore platforms, and industries that operate with corrosive and combustible gas and dust. Since we understand the importance of pilot lights in such dangerous workplaces, the utmost care has been taken to design and select the product’s materials.

The operation explosion-proof pilot light is developed keeping in mind that they should meet the requirements like power distribution, signaling, monitoring, and other electrical functions inside unsafe and volatile environments of the factories.

  • The pilot lights are composed of high-quality thermoplastic
  • It gets IP66 level of protection for enhanced performance in the factories and control station for which it is sealed with EPDM
  • For the Exd sections, high-quality thermostatic materials are used
  • The pilot lights can be installed on a standard cover, a mounting rail, or other customized places as per the client’s requirement.

We offer a wide range of pilot lights that can be customized as just the light head or bought as a complete unit. Moreover, the pilot lights we offer can be replaced when they expire and are available in different colors, shapes, and sizes. Most of the pilot lights we offer are compatible with different voltages.

Typically, LED lamp versions have a better life span and can last thousands of hours. Also, most of the pilot lights we offer are of a standard module; hence it is possible to have it as an interchangeable operator and a contact block.
