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/in2, they are designed for use with heat transfer oil and have a maximum operating temperature of 550oF (288oC). 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 250oF (121oC). 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 HeaterThermal 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.
