SL Series Hot Oil Heating Systems

SL SERIES: CUSTOM ENGINEERED ELECTRIC HOT OIL SYSTEMS 

Custom Engineered Electric Heating Temperature Control Systems. Get the specific features and benefits that you need to run your process operation.

SL Series Systems deliver the Safe Reliable Performance HEAT is known for in a packaged system that is precisely engineered to your process. Our engineering team will work with you to design a system based on a specific and unique process or application. SL Series systems typically include a Circulating Pump, Electric Heater, Expansion Tank, Cooling circuit, and Control Panel. Design capability for maximum operating temperatures up to 750°F.

SL Series systems are constructed with either Carbon Steel or Stainless-Steel wetted materials, insulated with Non-Wicking Cellular Glass Insulation, and packaged, skid-wired, and assembled on a drip-proof, seal-welded plate-and-channel fluid containment base. 

HEAT offers four distinct levels of customization, ranging from minimal customization to fully built-to-specification designs. Each unique system undergoes a Factory Acceptance Test in accordance with HEAT standard practice prior to shipment.
