SW SERIES: METAL OVER-THE-SIDE HEATERS

• Simplified and convenient mounting: Unlike other immersion heaters (such as flanged or screw plug heaters), the SW Series offers a convenient mounting solution, eliminating the need for tank penetration. These heaters can be bolted to the side of the tank. The “over-the-side” design also allows for removal, whether for cleaning or replacement, without having to drain the tank.
• Terminal enclosure: Our SW Series utilizes a flame-retardant and vapor-resistant polypropylene enclosure designed for the metal finishing industry’s challenging environments. Three feet of conduit and four feet of lead wire come standard and allow for easy installation. Longer lengths are also available.
• Thermal protector: The SW Series come standard with either a replaceable or resettable thermal protector suitable for solutions up to 180°F, 230°F, and 300°F. Please note the thermal protector must be connected to a compatible control for safe operation.

• Voltage: SW Series heaters feature voltages up to 600V, ensuring our heaters can be engineered to meet your power supply configurations and operational needs.
• Wattage & watt densities: Over-the-side immersion heaters offer a wide range of wattages and watt density ratings. The standard watt density is 35 watts per square inch but derated versions are also available (add “D” to start of the part number).
• Dimensions: Customize the immersion length, cold section, and element configurations to fit your tank. Our team can design an over-the-side heater that’s perfectly sized to fit your space constraints while delivering the heat output you need.
• Element numbers: These heaters can be configured with either 3-, 6-, or 12-element configurations for the efficient and cost-effective heating of both small and large tanks. The 12-element configuration is a particularly powerful space-saving design that puts up to 36kW into a tank, relieving the need to use multiple smaller heaters.
• Element sheath material: Choose from a variety of sheath materials, including 304 or 316 Stainless Steel, Incoloy® 800, and Titanium. Ask us what material would provide the best lifespan and value for your metal finishing application.

Metal over-the-side heaters are commonly used in open-top tanks and process baths where parts are dipped for cleaning, coating, or chemical treatment. Their rugged construction and corrosion-resistant materials make them ideal for demanding industrial environments. Common Industries Served:

• Metal Finishing & Plating: Aqueous alkaline solutions, plating, and phosphate tanks.
• General Industrial: Provide reliable heat for caustics, detergents, and custom chemical solutions used across manufacturing processes.

• Replaceable T1: Suitable for solutions with temperatures up to 180°F (82°C)
• Replaceable T4: For solutions with temperatures between 180 to 230°F (82 to 110°C)
• Replaceable T5: For solutions from 230 to 300°F (Not UL-Listed)
• Resettable T2:  Suitable for solutions with temperatures up to 180°F (82°C)
• Resettable T6: For solutions from 180 to 230°F (82 to 110°C)
