An adhesive supply unit is provided with a tank having fins which maximize the heat exchange area of the tank for melting hot melt adhesive. Each fin features a cut out which is of such a size and shape as to allow the placement of a block of unmelted adhesive in the tank while at the same time maximizing the surface area of the fins to improve heat transfer. An electronics control unit is located adjacent one end of the tank and has a fan located in the top of the cabinet over the control unit which fan blows in ambient air from the outside downwardly over the electronic controls contributing to an efficient cooling of the electronics. A coupler is used to align the pump and air motor located on the bottom of the device consists of a sleeve which supports the shaft and an outer bore which fits into corresponding bores in both the air motor and pump thereby aligning all three items and providing a sealing function as well.
