Aluma Finned Immersion Heater

The Aluma-Finned Immersion heater is specially designed where low wattage density surface applications are required. Available in aluminum (T-6360), standard carbon steel, stainless steel, and exotic materials such as titanium, the Finns can be extruded or CNC-machined depending on the material chosen. Specifically, the Finns are extruded vertically when employing the aluminum design and CNC-machined horizontally for all other materials. Such a technology increases surface area per square inch while allowing more power per linear inch but maintains low watt densities on the surface.

Aluma-Finned Immersion heaters can serve customers in diverse industries surrounding oil and gas, gas dryers, gas turbines, chemical, power, asphalt, and marine, and other industries which require heating a liquid either by circulation or by stagnancy.

The different types of liquid that can be heated with Aluma heaters are oil, benzene, glycol, asphalt, acetone, mineral oils, sea water and air.

All heaters are available in both single and three-phase with voltages available ranging from 208V to 600V with a maximum allowed capacity of 96KW. TriVolt can offer multiple stages per heater as required.

TriVolt heaters can be mounted on a flange ranging from 3” to 10” on area both 150 to 300 PSI; while for higher pressures applications TriVolt works in conjunction with CWSB-ASME for separate certification. The Aluma-Finned Immersion heater can operate up to 25W/PSI depending on the particularity of the application, mechanical dimensions and operating temperatures.

Where space is limited, TriVolt can offer our 3” NPT hex mounting screw plug. This option is only offered on the standard carbon steel, stainless steel and titanium materials.

All heaters are available with NEMA 1, 4 Enclosures compliant with CSA-CUS and HazLoc certifications.

TriVolt’s innovative proprietary Solid Work Simulation software is employed to determine the exact material and wattage per square inch required for any application.

All TriVolt products have undergone stringent internal and CSA testing, CAN/CSA-C22.2 No. 72-10 (2013) and UL 499 Thirteenth Editions; Class 2871-02 and 2871-82. HazLoc certification pending.
