BS-4535A series shrink tunnel ( 18 X 14 INCH ) adopts stainless steel heater and high power blowing motor for shrinking tunnel, characterized by quick heat-up, strong and even blowing. Both conveying speed and temperature of tunnel can be changed according to different sizes and output requirements of different objects. Features: 1. Speed of conveying belt can be regulated at will by electric speed controller. 2. Overheating-proof for machine surface by adopting double insulation mechanism. 3. With temperature- resistant and heat-insulating cord fabric to be against heat loss. 4. Adopt the solid roller packed in thermo-stable silicone tube as conveying chain, which can stand heavy-duty object without deformation.
