Outdoor duct heater

Short Description:

The outdoor 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

Outdoor 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 heater outdoor unit is equipped with an awning to prevent the heater from shortening the life of the sun and rain.

In fact, if the heater is installed outdoors, the junction box and shell structure of the heater are designed and manufactured in accordance with the protection level, that is to say, the electric heater itself is not afraid of sun and rain, even if the rainstorm will not affect the normal operation of the heater. But now the air quality is getting worse and worse, there is often acid rain, and the solar direct electric heater will accelerate the aging of the heater and affect the effect of the heater, if the canopy is added, as long as the installation is appropriate, it can slow down the corrosion rate of the various components of the electric heater and extend the service life of the electric heater.

When installing an awning to the electric heater, the awning distance from the top of the electric heater should be more than 30cm, and the front edge of the awning should not affect the air output of the electric heater, so as to avoid the awning affecting the normal heat dissipation of the electric heater, and keep the surrounding ventilation of the electric heater smooth.

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).
