FAQ 

Q1: Does a gas tunnel furnace save more money than an electric heating tunnel furnace?

A: Yes. Under the same heat demand conditions, the energy cost of gas heating is generally 30% to 50% lower than electric heating.

Q2: How is the explosion-proof safety performance of the equipment ensured?

A: The equipment is equipped with a highly sensitive ignition gas valve assembly, automatic flame failure protection, and forced furnace chamber ventilation system to ensure that gas does not leak or accumulate.

Q3: How is temperature uniformity inside the furnace guaranteed?

A: The furnace uses multiple independent temperature zones combined with a high-performance hot air circulation system to ensure minimal temperature differences between the upper, lower, left, and right areas inside the furnace chamber.

Q4: Can the length and width of the tunnel furnace be customized?

A: Yes. The equipment can be customized according to the material size, baking or heat treatment process, production capacity requirements, and available factory space.

Q5: What should be paid attention to during daily maintenance?

A: Regularly check the gas pipeline sealing performance, clean carbon deposits from burner nozzles, and apply high-temperature lubricant to the transmission chains to ensure stable operation and extend service life.
