Process Heating Company’s (PHCo’s) Lo-Density® Flanged Immersion Heaters are perfect for use in tanks, large vats, and reservoirs. These heaters consist of a standard 150# or 300# flange for mounting and our exclusive heating elements. The elements are drywell-type, utilizing low-watt-density design. The drywells allow the elements to be serviced or replaced without draining the tank – a huge advantage if maintenance is required. The low-watt-density design keeps the element sheath temperature low, reducing the chance of coking or buildup on the heater. The flange and heater tubes can be made of mild steel or various grades of stainless steel, depending on your application. These direct immersion heaters are virtually 100% efficient (all the energy consumed is transferred to your process), and they are easily controlled. The heaters can be supplied either with our custom, UL-Listed industrial control panels, integrally mounted and wired to the heaters, or without, if controls are already present. Flanged Immersion Heaters are one of the most widely used methods of heating liquids. PHCo offers many advantages over traditional-style tubular elements.
Lo-Density® Technology
All heaters are built with our Lo-Density® design to eliminate the possibility of coking or damaging your temperature-sensitive products. Heating elements carry our standard 5-year replacement guarantee, and are listed by ETL.
Drywell Design
Heating elements are installed in drywells, making them accessible from outside the tank and eliminating the need to drain it when servicing the elements.
Environmentally Friendly
No burners. No fossil fuels. No stacks to monitor for emissions. No air-quality or boiler permits to worry about.
UL-Listed Controls
Operation is completely automatic. The main indicating temperature control regulates the discharge product temperature. A high-limit control is included for safety. Main disconnect and individual fused heat circuits provide overcurrent protection. All components are mounted and prewired in a NEMA Type-4 enclosure.
