● Tunnel type curing ovens are designed with a conveyor belt system that moves workpieces through a tunnel-shaped chamber.

● The oven is typically long and narrow, with the conveyor belt running through the center of the chamber.

● Heating elements are positioned along the walls or ceiling of the tunnel to provide consistent heat distribution. And wind curtain at both ends to efficiently prevent heat loss of the oven.

● Tunnel type ovens are well-suited for continuous production lines with high throughput requirements.

Reasonable heat ventilation system design makes air circulation perfectly balanced and keeps furnace temperature stable. Gas burner type, 100% of heat flows into the furnace, high efficiency and no waste.

Tunnel ovens can be built directly on the ground, which is relatively cheaper than bridge curing ovens, but its thermal insulation is relatively weak due to heat conversion. This design is more suitable for long workpieces rather than wide workpieces. If the tunnel door is too wide, the air curtain will not be strong enough for heat conversion, which will cause heat loss, slowing down the oven heating speed and increasing electricity bills.

If you choose the power and free conveyor system,the tunnel oven will be suitable for it.
