　　IIIRB-2000/127(A)Explosion proof electric heaters for coal minesStructural features:

　　1. The heater consists of a radiator, a power inlet chamber, a wiring room, and a dust cover. There are 4 heating elements installed inside the radiator; There is a temperature controller connected in series in the wiring room, and a power bus is used to connect the heating element; The wiring room will connect the 127V power supply from the supporting equipment through the lead device, and there will be terminal posts leading to the wiring room; Dust cover is used to prevent dust from accumulating on the radiator. The temperature is controlled by both a temperature controller and a temperature fuse. When it reaches 120 ℃, the temperature fuse will melt and power off.

　　2. Heater radiator: gray cast iron is used as the radiator, with strong continuous heat dissipation ability.

　　3. Heating element of heater: The heating element adopts the standard DIN 44921-3-1985 "Requirements for Metal Shell and Tube Electric Heating Elements", which has the characteristics of stable heating, safety and reliability.

　　4. Heater thermostat: KSD type thermostat that complies with JB/T 3751-1997 "Household and Similar Use Bimetallic Temperature Controllers" standard is used, which has the advantages of reliable operation and long mechanical life.

　　IIIRB-2000/127(A)Explosion proof electric heaters for coal minesUsage conditions:

　　1. Environmental temperature: -20 ℃ to+40 ℃;

　　2. Relative humidity of the environment: ≤ 98% (+25 ℃);

　　3. Atmospheric pressure: 86kPa~106kPa;

　　According to Article 220 of the "Coal Mine Safety Regulations" (2004), when the ventilation room is located outside the industrial square, except for mines with gas emission areas and coal (rock) and gas outburst mines, flameproof furnaces or explosion-proof electric heaters can be used for heating.

　　RB-2000/127(A)Explosion proof electric heaters for coal minesAlso known as an electric heater, it is a device used to provide heating. Suitable for fixed positions in coal mine underground chambers with methane or coal dust explosion hazards as heating equipment.
