Insulation layer surface of air duct heater

An air heater should be added on the surface of the insulating layer. In the use of air heaters, the insulation is only at the outlet pipe of the electric heater, and the heater surface itself does not have any heat treatment. The comparison data shows that increasing the heat insulation layer can reduce the energy consumption by 5% to 10%. It is very important to save energy consumption for long-term operation on the surface of the air heater. At the same time, the insulation layer should be installed in the pipeline, and the insulation layer should be installed in the air heater.
