Product Description
The B Series LED luminaire is an explosion-proof choice for marine and hazardous applications. They can be used in locations where moisture, dirt, dust, corrosion and vibration may be present, or areas where wind, water, snow or high ambient can be expected.
Class I, Division 2 covers areas where flammable gases or vapours are present only under abnormal conditions, such as a leak or a ventilation failure. The Class II, Division 1 and 2 ratings extend the same housing to combustible-dust locations, and the Class III listing to ignitable fibres. Typical applications include marine and offshore installations, fuel and solvent handling, chemical processing and wastewater treatment.
