Watlow Screw Plug Heaters are primarily used for direct immersion in water, oils, viscous materials, solvents, process solutions and molten materials as well as air and gases. Additionally, round and flat surface tubular elements (Watrod & Firebar) can be used for surface heating. Watrod & Firebar heating elements may be purchased separately, or fabricated into process heating assemblies. Both elements and assemblies are available from stock. They can be configured with a variety of watt and volt ratings, terminations, sheath materials and mounting options to satisfy the most demanding applications. If the stock products do not meet your applications needs, the optimum heater can be custom engineered.
