Bolt Heaters are constructed with one of the industry’s most efficient and highest quality heating elements—Hi-Density (swaged) Cartridge Heaters; with close tolerance fits, watt densities of 100 watts per square inch are obtainable – 65% higher than standard cartridge or tubular heating elements can deliver. The higher wattage on Hi-Density Bolt Heaters means quicker heat-up time and minimum heat loss to the area surrounding the bolt.
Bolt heaters are manufactured with a wooden handle attached to a terminal conduit box for easy insertion and removal.
