The shrink tunnel can be used with angle welders, frame welders or super magnet sealers. Packed products in heat-shrinkable foils are shrunk with hot air. The hot air temperature is electronically regulated and can, of course, be read on the display. The conveyor belt has a speed control of 1 to 20 m / min. All models are modular, so in the future they may be equipped with additional options to enhance the functionality of the tunnel.
