There are two sets of deviation sensors on our cooling tunnel. When belt moves to left or right side, the pneumatic cylinders will work and make the belt move in the middle.

Why we need to fill Freon or refrigerant when cooling tunnels arrives our factory?

We have to discharge the Freon or refrigerant before packaging so as to avoid leakage during shipping. Also, our customs requires us to ship the cooling compressors without Freon or refrigerant.
