    Watlow FLUENT® In-Line Heaters

    November 21st 2023

    Watlow’s FLUENT® in-line heater is a small, lightweight, robust, and high-performance heater that can replace both traditional immersion or heaters that wrap around tubes as part of a thermal system.

    FLUENT® is designed as an integrated solution that can replace multiple components in a system, thus reducing overall system cost and complexity. Advanced layered heater technology means FLUENT® heaters are lighter and more compact than equivalent wattage circulation or cast-in heaters, again assisting overall system design and performance.

    FLUENT® features and benefits

    FLUENT® features all-stainless-steel construction for a clean, non-contaminating heat source, while Watlow’s innovative thermal spray technology allows the heater to use its entire surface to produce heat, optimizing heat transfer and temperature uniformity.

    Its high watt density allows FLUENT® heaters to generate ultra-fast response for higher overall system performance and on-demand startup. The heating element sits outside the fluid flow path and the heater circuit is patterned precisely and repeatably leading to excellent reliability The FLUENT® design also incorporates an internal thermocouple for robust high limit control.

    In addition, FLUENT® heaters can also promote increased efficiency in many applications.  Compared to liquid heating applications where a traditional heater is immersed into a tank and heats the entire volume of liquid regardless of how much will be used, FLUENT® heaters only heat the liquid that will be used in the process.  The low mass of the heater also requires less energy to heat than traditional heaters with much higher weight for the same wattage level.
