Explosion-proof duct heater

Short Description:

The air duct heater distributes high temperature resistance wire uniformly in the high temperature resistant stainless steel fin tube, and fills the void with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. When the current in the high-temperature resistance wire passes through, the heat generated is diffused to the surface of the metal tube through the crystalline magnesium oxide powder, and then transferred to the heated part or air gas to achieve the purpose of heating.

Working principle

Explosion-proof duct heater is mainly used for air heating in the duct, specifications are divided into low temperature, medium temperature, high temperature three forms, the common place in the structure is the use of steel plate to support the electric pipe to reduce the vibration of the electric pipe, the junction box is equipped with overtemperature control device. In addition to the control of the overtemperature protection, but also installed between the fan and the heater, to ensure that the electric heater must be started after the fan, before and after the heater added a differential pressure device, in case of fan failure, the channel heater heating gas pressure generally should not exceed 0.3Kg/cm2, if you need to exceed the above pressure, please choose the circulating electric heater; Low temperature heater gas heating higher temperature does not exceed 160℃; Medium temperature type does not exceed 260℃; High temperature type does not exceed 500℃.

Working condition application overview

The heating principle of explosion-proof air duct heaters mainly relies on the process of converting electrical energy into heat energy, providing a comfortable room temperature by heating air or meeting specific process requirements. Its design fully considers safety, especially in explosive environments, explosion-proof performance is crucial.

The explosion-proof air duct heater is mainly composed of heating element, fan, control system and enclosure. The heating element is the core of the entire system, and the fan is responsible for producing air flow, drawing cold air into the heater, heating it through the heating element, and then transporting it through the air duct to the area that needs to be heated.

After the cold air enters the heater, the temperature gradually rises through the heating action of the heating element. In the heating process, the explosion-proof air duct heater adopts a special explosion-proof design, such as using explosion-proof electrical components, setting explosion-proof junction boxes, etc., to ensure that even if there is an abnormal situation in the heating process, it can effectively prevent sparks or high temperature caused by explosion.

In addition, the control system of explosion-proof air duct heater has accurate temperature control and wind speed control functions, which can be adjusted according to actual needs to ensure stable and safe heating effect. At the same time, the system is also equipped with safety protection devices, such as over-temperature protection, over-current protection, etc., once an abnormal situation occurs, it can immediately cut off the power supply to prevent accidents.

Application

Air duct electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 500 ° C. It has been widely used in aerospace, weapons industry, chemical industry and many scientific research and production laboratories in colleges and universities. It is especially suitable for automatic temperature control and high flow and high temperature combined system and accessory test. The electric air heater can be used in a wide range: it can heat any gas, and the generated hot air is dry and water-free, non-conductive, non-burning, non-explosive, non-chemical corrosion, pollution-free, safe and reliable, and the heated space is heated fast (controllable).
