No matter what type of fluid is being heated or the fluid flow conditions, consider the specific application environment before specifying the heater watt density to ensure good results.

Heat is required in applications to prevent media freezing or to provide viscosity control in fluids like oil. Heat also can be used to prevent condensation on an electrical control box or a camera lens mounted outdoors.

Smart temperature management and control are important in applications ranging from hot runner injection molding in the plastics industry to form, fill and seal systems for packaging, to rubber molding and to food production.

Hot-oil circulation heaters, unitized asphalt storage-tank heaters, drop-in underground tank heaters and rigid tubular drywell tank heaters offer energy-efficient heating. 

Proper selection of the heating element for a given application ensures longevity of the heater.

Series TRO, TSO and TSOL use a dielectric material to support the coiled heating elements, and the heater tube is pressed to increase thermal conductivity.

The 0.125" (3.175 mm) cartridge heater was developed for OEMs that required a small but high power thermal solution.

Being aware of potential dangers can help prevent electric tank heat explosions.
