Heat blowers are versatile tools that can be used for a wide range of applications. They can also be paired with other materials and equipment to create heating systems, such as a shrink tunnel.
Elements of a heat shrink tunnel system
Heat shrink tunnel systems are comprised of heated tunnels and a conveyor that moves items through to provide even warming. Heat blowers can be directed into the enclosure and affixed to the conveyor to create these systems.
One or two blowers may be used in the tunnel system, depending on your needs and restrictions. The heat blower should be located by the side of the tunnel with the nozzle entering at the side. The conveyor brings the items to be heated through the air stream steadily so as to not heat one area or item more than another.
The heat shrink system can be used for a number of purposes, such as shrinking plastic wrap around products like bottles or bundles of items.
Heat shrink tunnel system safety points
Heat blowers can be dangerous tools when not used properly. The temperature of the air stream can get as high as 750 degrees Fahrenheit, which is enough to cause serious burns or fire.
To prepare your heat shrink tunnel for safe use, make sure there aren’t any flammable materials nearby or used in the construction of the tunnel. Even after you do this, make sure you have a working fire extinguisher nearby just in case.
The heat that goes into the tunnel must also have a way to escape. If it doesn’t, the tunnel and products inside could be damaged, and the heat blower can overheat. Make sure you have proper ventilation in the tunnel so that ambient air can pass through. Also, measure the inlet and outlet for the heated air – they should be the same size so all hot air can leave the tunnel at the same rate it enters.
Position the heat blower horizontally. This is the most stable arrangement for the heat blower, and therefore the safest.
