Pagination or Media Count:
The patents in the preferred embodiment, comprises a heat-shrink comma gun for heat-shrink applications in potentially explosive or flammable conditions, by using a non-electric non-flame producing, and non-sparking heat source. A hand-held housing has a nozzle attached thereto. A heat transfer element is attached within the housing and extends into the nozzle. The space within the nozzle formed between the heat transfer element and the nozzle defines an air heating chamber. A chemically reactive heat cartridge, contained within the heat transfer element, is activated via a striking force. The heat cartridge radiates heat along the heat transfer element into the air heating chamber. Air under pressure is supplied to the air heating chamber and exits the nozzle as hot air under pressure.
