Process Heating Company’s Lo-Density® Drop-In Tank Heaters

Lo-Density® drop-in tank heaters from Process Heating Company (PHCo), Seattle, Washington, are designed for 100 percent efficient heating of asphalt and emulsions in both underground tanks and distributor trucks. The drop-in heater is installed by simply dropping it through the tank’s manway and attaching it horizontally to the tank bottom. If needed, multiple heaters can be laid end-to-end using flexible, high-temperature power leads. Lo-Density, electric, drywell-style heat requires no permits or stacks.

Lo-Density drop-in heaters are also appropriate for above-ground applications, including static installations up to 50,000 gallons, as well as distributor trucks. The heaters install the same way as in underground tanks. Above-ground tanks must have a minimum of 3 inches of fiberglass (or similar) insulation and weatherproofing.

Drop-in heaters from PHCo are available for tank capacities ranging from 1,000 gallons to 50,000 gallons, and are designed to maintain temperatures from 125 degrees F to 325 degrees F. The heaters’ recommended capacities include sufficient heat to maintain the temperature shown, plus a resere capacity for heat-up requirements. The drop-in tank heater kit includes a UL-listed control panel with digital thermostats for tank content temperature control. The complete kit includes heaters, controls, temperature sensors, wiring boxes and transition fittings for the tank top.
