ABSTRACT:
A manifold for a liquid material dispenser has a unitary manifold body with process air and liquid material passages formed therethrough. Heaters for heating the process air and liquid material are both coupled directly to the manifold body and cooperate to simultaneously heat both the air and liquid material. The air and liquid material heaters may be arranged in either a generally vertical orientation, or a horizontal orientation with respect to the manifold body. In one embodiment, the process air heater includes a cylindrical member which is substantially exposed to the process air to optimize heat transfer from the cylindrical member to the process air.
