Heavy Duty Electric Air Duct Heater - High-Temperature Heating Solutions from China Suppliers & Factory
Electric Air Duct Heater
The pipe heater consists of two parts: the heater body and the control system. The heating body uses a stainless steel electric heating tube as the heating element. There are multiple guide plates inside the product to guide the medium to fully contact the flange heating core in the heater cavity, prolonging the residence time of the medium in the heating cavity, so that the medium is fully and evenly heated and the heat exchange is improved.
After reaching the required temperature, it is sent to the heat-using equipment. The temperature control system of the heater will automatically adjust the power of the heater according to the signal feedback from the temperature sensor at the outlet of the heater, saving energy while ensuring the heating demand.
The electronic control system has a built-in overheating protection function. If the temperature sensor in the heater cavity feedbacks that the temperature in the heater cavity is too high or there is an empty burning condition, the power supply will be cut off immediately to prevent the material from deteriorating due to excessive temperature, causing coking, carbonization, and damage to the heating tube due to empty burning, so as to ensure the normal operation of the electric heater.
Frequently Asked Questions
What are the main components of the Electric Air Duct Heater?
The heater consists of two main parts: the heater body, which utilizes a stainless steel electric heating tube as the heating element, and the electronic control system.
How does the heater ensure uniform medium heating?
It features multiple internal guide plates that direct the medium to fully contact the flange heating core. This design extends the residence time of the medium in the heating cavity, leading to even heating and improved heat exchange.
How does the temperature control system save energy?
The system automatically adjusts the heating power based on real-time signal feedback from the temperature sensor located at the heater's outlet, matching actual heating demand.
What safety mechanisms protect the heater from damage?
The control system has a built-in overheating protection function. It immediately cuts off the power supply if the sensor detects excessive cavity temperatures or an empty burning condition.
What risks are prevented by the automatic shutdown system?
The automatic shutdown prevents material deterioration, coking, carbonization, and physical damage to the heating tube that can occur from overheating or empty burning.
