What should I do if there is a problem with the duct heater?

Pipe heaters are a common industrial device, acting as hot air generators. Pipe heating, as a preheating device, can save energy in production and is highly recommended.

Pipe heaters are primarily electric heating devices that heat the medium, converting electricity into heat. They utilize stainless steel heating tubes as the heating element. Multiple internal deflectors guide the medium's residence time within the inner chamber, ensuring uniform heat transfer and improving efficiency.

Problems and Solutions with Pipe Heaters

1. Poor Pipe Circulation

Solution: Open the bleed valves on the heater and piping to release air. This usually resolves poor circulation. (Note: Avoid large bends in the piping, as this will prevent circulation.)

2. The heater is not functioning properly upon initial use.

Solution: Verify that the heater's water valve is open and that the heater rotates freely. The first time the heater is operated after installation, it may not function properly due to the lack of oil in the oil pipe. It may take several attempts to restore proper operation. Cleaning the glow plugs and fuel vaporizer screen is generally not necessary. However, if the heater is dripping, smoking, or failing to burn, remove the glow plugs and vaporizer screen and reinstall them before turning the heater on.

3. During use, if the piping is blocked, the heater body temperature may overheat. In this case, the manual reset thermal fuse on the heater will automatically trip, stopping the fuel supply and allowing the heater to cool gradually.

Solution: If this occurs, check that the water pipes are clear and not pinched. Press the thermal fuse reset button in the center of the rubber cover and restart the heater.

4. The indicator light does not illuminate when the heater is turned on.

Solution: Check that the main power is on, the heater fuse is not blown, the wiring harness is securely connected, and the control box is not damaged.

5. If the heater fails to burn or burns erratically, and there is no dripping or smoking at the exhaust port,

Solution: Check the oil pump and piping for blockages, looseness, or leaks.
