Closed-Loop Heating via Thermal Fluid Heaters

Thermal fluid heaters are offered in 0.5 to 75 million
BTU/hr in horizontal or vertical, two-pass or three-pass models, and up-fired or down-fired configurations. Used in closed-loop thermal fluid heat transfer systems, the heaters are designed around a helical coil. Thermal fluid flows through the helical coil, gaining radiant and convective heat from hot burner gases. The heated thermal fluid transfers heat to end users such as tanks, presses, dryers, reactors, chillers, extruders, steam generators or other equipment. Heater features include factory-preassembled design, optional on-site setup and startup, and factory service options. All are customized to meet customer specifications.

Process Heating Co heaters

Low Watt Density, Drywell Heaters Designed for Vats, Tanks, Reservoirs

Designed for use in tanks, large vats and reservoirs, flanged immersion heaters consist of a 150 or 300 lb flange for mounting and exclusive heating elements. The element’s dry well and low density design allow the heater to be serviced or replaced without draining the tank. The low watt density design keeps the element sheath temperature low, reducing the chance of heater coking or buildup. The heaters can be supplied with custom UL-listed industrial control panels integrally mounted and wired to the heaters, or without, if controls already are present. The flange and heater tubes can be made of mild steel or various grades of stainless steel.
