Oil Immersion HeatersUsed for oil preheating, oil baths, wax and other heat transfer fluids, oil immersion heaters provide years of trouble-free service when the tubes are completely covered with fluid, used on correct voltage and kept free of carbonization. With watt densities of 16 to 22 W/in 2, they are designed for use with heat transfer oil and have a maximum operating temperature of 550°F (288°C). Heaters with lower watt densities are designed for use with Bunker C fuel oil preheaters and line and suction heaters with a maximum operating temperature of 250°F (121°C). All are constructed with steel heads and tubing. The TRO, TSO and TSOL Series use a dielectric material to support the coiled heating elements, and the heater tube is pressed to increase thermal conductivity.

Three-Pass Heater Has Lower Flux RateThermal fluid heater employs a fired burner and two helical coils, one inside the other, to provide up to twice the life of other three-pass heaters while providing the required amount of heating. Its lower flux rate means that its helical coils will be subjected to much lower thermal energy, especially radiant energy, than is usual in a three-pass heater. This also means that thermal fluid flowing inside the coils will have a much lower film temperature. To achieve the lower flux rate, the heater is somewhat larger than a three-pass heater with higher flux rates.

Flanged Immersion HeatersDesigned 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 them 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.

Fluid Tracing SystemQMax utilizes high efficiency conductive heat transfer rather than convective heat transfer. Its design maximizes the heat input of a regular stainless steel or copper tube tracer. The heating surface area is increased to as much as 3" using highly conductive aluminum. A single tracer and the fluid tracing system (FTS) can achieve the same results as multiple tube tracers or even jacketed pipe, according to the company. The heat transfer equipment can be used for process temperature or minimum pipe wall temperature maintenance; light-duty process heatup; and critical process freeze protections.

Self-Regulating Heating Cable
SR Trace automatically varies its heat output with changes in ambient temperature. Because it is self-regulating, it can be safely wrapped over itself if necessary when installed on pipes, valves or flanges. The heating cable provides freeze protection for plastic or metal pipes and vessels in ambient temperatures down to -40°F (-40°C). It also will maintain liquids in pipes at a constant temperature to prevent degradation of the liquid, or to preserve required viscosity for flow conditions.
