BGY4/BGY2 Constant Temperature Flameproof Tubular Electric Heater Details
BGY4/BGY2 Constant Temperature Flameproof Tubular Electric Heater Manufacturer Introduction:
Explosion-proof electric heating tubes convert electrical energy into heat energy to heat the materials that need to be heated.
The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the temperature sensor signal at the output port, making the medium temperature at the output port uniform; when the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, avoiding overheating of the heated material causing coking, deterioration, carbonization, and in severe cases, burning out the heating element, effectively extending the service life of the electric heater.
During operation, using the path designed by fluid thermodynamics principles, the low-temperature fluid medium enters its input port through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, takes away the high-temperature heat energy generated by the electric heating element during operation, raises the temperature of the heated medium, and the electric heater outlet obtains the high-temperature medium required by the process.
Characteristics of Explosion-proof Electric Heating Tubes
Explosion-proof electric heating tubes are made of materials such as SUS304, 316L, etc. BGY4/BGY2 Constant Temperature Flameproof Tubular Electric Heater Manufacturer For high power requirements, better materials such as incoloy800, incoloy840, etc. can be selected. Explosion-proof electric heating tubes evenly distribute high-temperature resistance wires inside high-temperature resistant stainless steel seamless tubes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation performance, making the explosion-proof electric heating tubes have high thermal efficiency, uniform heat dissipation, and long service life.
