Thermal Fluid Heating Systems for Your Process
Thermal Fluid Heater Options
From the pre-engineered HC2 Heaters to fully custom systems, Sigma Thermal designs, manufactures, and supports thermal fluid heating solutions built for reliable, efficient performance.
Thermal fluid heating delivers precise, high temperature process heat at low operating pressures — without the water treatment, permitting, and maintenance demands of steam. Heaters are available in gas-fired, oil-fired, electric, and biomass-fired configurations. Select from one of the below heater designs for detailed information.
Not Every Project Needs a Custom Heater
Pre-engineered HC2 Thermal Fluid Heaters and SHOTS Electric Heaters bring you shorter lead times, easy installation, and proven efficiency. Take a closer look at the design, construction, and capabilities behind our systems.

Packaged Components Completely Integrated System
Sigma Thermal systems arrive as complete, skid-mounted packages, not a collection of parts to coordinate in the field. Each packaged system can include circulation pumps, expansion and storage tanks, valving, instrumentation, and a fully integrated control system -- engineered to work together and tested before they ever reach your site. The result: faster installation, simpler commissioning, and a single point of accountability.

Recover More Heat with Economizers
With the typical elevated operating temperatures associated with thermal oil systems, it can be difficult to obtain high efficiencies in the heater alone. Sigma Thermal offers a wide variety of economizers to fit your process requirements, increase your thermal efficiencies, and lower your operating costs. For most operations, the fuel savings pay for the investment quickly -- and keep paying for the life of the system. Ask our team whether an economizer makes sense for your application.
