The BHM-10 Hot Melt Unit is a hot melt applicator system developed to melt and pump high viscosity butyl rubber-based sealant. The melt unit features a 10 lb (4.5 kg) capacity tank. The cylindrical design accepts briquette form butyl sealants, which are converted to fluid state and pumped by an electric motor-driven gear pump through an L2 Handgun/hose assembly.

A rotating chain and scraper assembly in the tank propels the molten butyl sealant to the pump inlet port. A 38/31 rpm 60/50 Hz 1/6 hp motor and flow control valve provide output control. Tank temperature is regulated by an adjustable bimetallic controller mounted directly on the melt unit base. Hose temperature is controlled by an adjustable thermostat with capillary bulb sensor. The BHM-10 Hot Melt Unit features the proven all-electric heating and pumping system. The melt unit is housed in an industrial-grade sheet metal enclosure and comes with a standard 8 ft (2.44 m) handgun/hose assembly; a 12 ft (3.66 m) hose assembly is optional.
