Explosion-proof Electric Heating Plate|Explosion-proof Heating Plate

1. Features and Applications
    The main feature of this series of explosion-proof temperature-controlled heaters is that they are suitable for heating in environments with water and high humidity. They are mainly used for winter insulation in explosive hazardous areas and high-humidity environments. This product is a fully cast aluminum alloy finned heater with low design power load and large heat dissipation area. It is equipped with dual temperature protection devices.
    The explosion-proof performance of this series of heaters complies with GB3836.1—2000 "Electrical Equipment for Explosive Gas Atmospheres Part 1: General Requirements" and GB3836.2—2000 "Electrical Equipment for Explosive Gas Atmospheres Part 2: Flameproof Enclosure 'd'". The explosion-proof type is flameproof, with explosion-proof marking ExdIIBT3. It has been reviewed and tested by the national designated explosion-proof inspection unit for drawings, technical documents, and samples, and has obtained the product explosion-proof certificate.
