Lo-Density Rigid Tubular Drywell Tank Heaters

Process Heating Company Lo-Density Rigid Tubular Drywell Tank Heaters provide safe and consistent overnight heat for asphalt emulsion distributor truck tanks. This efficient heating system allows operators to simply plug the heater in at the end of the day, maintaining the emulsion at the correct temperature overnight or over a weekend.

These low-watt density tank heaters safely dissipate controlled heat on the heater’s sheath, with no open flame, providing even heat distribution throughout the reservoir to prevent coking or damaging of temperature-sensitive emulsion material. Process Heating Company’s unique drywell-style elements reside inside the sheath, making them accessible from outside of the tank and eliminating the need to drain the tank to service the elements. The Rigid Heaters can be installed as new or as retrofit equipment.

UL-listed controls located on the distributor truck fender offer easy-to-use complete automation of temperature regulation. The main indicating temperature control regulates the product temperature and includes a high-limit control for safety. The main disconnect and individually fused heat circuits provide overcurrent protection. All components are mounted and prewired in a UL-listed, weatherproof enclosure.

Each heating unit is designed for the individual application, and can be customized to meet the specific needs of the manufacturer or user for sheath diameter, number of elements and sheath length, or applications. Rigid Heaters can be made from mild steel or various grades of stainless steel, depending on the application. The sheath wall thickness ranges up to 0.3 inch for durability and corrosion resistance. The heating units are suitable for a kilowatt rating of up to 1,000 kW; voltages up to 600 VAC, in single or 3-phase; and watt densities of 3 watts per square inch of heater surface being standard. Terminal enclosures come standard with moisture resistance.
