Hot-oil circulation heaters, unitized asphalt storage-tank heaters, drop-in underground tank heaters and rigid tubular drywell tank heaters offer energy-efficient heating. The electrically heated devices direct all of the energy consumed into heating the product, without heat or emissions exhausted into the air. The company’s low watt-density tank-heating systems maintain a decreased heater sheath temperature, reducing potential damage to product while keeping buildup/coking to a minimum in tanks and hot oil systems. The heater’s drywell design allows service personnel to remove the heating elements and perform minimal required maintenance without draining the tank they are heating.
