Explosion-proof electric heater is a kind of equipment which consumes electric energy and converts it into heat energy to heat materials. Its planned surface power load is low and multiple protection is adopted, which greatly increases the safety and life of the electric heater. And according to the requirements of the heater circuit planning, can be completed when the outlet temperature, flow, pressure and other parameters of active control, energy-saving results are remarkable, almost 100% of the energy generated by the heat transfer to the heating medium.

The explosion-proof electric heater enters its inlet through pipeline under pressure effect in mission. Along the specific heating channel inside the electric heater container, it uses the way of hydrothermodynamic principle planning to take away the high-temperature heat energy from the mission of the electric heating element, so that the temperature of the heated medium increases, and the outlet of the electric heater obtains the high-temperature medium required by the process.

The high-pressure system inside the explosion-proof electric heater can supply the alarm signals of the heater in operation, high temperature, malfunction and shutdown to the DCS system. It can also withstand the operation slogans such as initiative and shutdown announced by DCS. A reliable and safe monitoring device is added to the electric heater system. However, the price reference of explosion-proof electric heater is relatively high.
