Systems and Services for Industries Across the Globe


When it comes to the heating and circulation of air in turbine systems, heating systems provide equipment longevity, efficiency, and highly controlled temperatures. Sigma Thermal’s products and services provide the best heating of air and fuel gas conditioning systems for the aerospace industry.



Edible oil deodorizers, for example, keep food color, smell, taste, and texture at its best, while steam superheating helps modern farmers get maximum efficiency and energy usage out of their equipment, ensuring that the steam flow through a turbine or engine remains a compressible gas.


Asphalt & Roofing

Industry solutions entail efficient and highly effective heat, circulation and turbine systems at controlled temperatures and provide fuel gas conditioning to help keep gas flow free of impurities.



From the proper heating of molded and extruded automotive components to the steam superheating that keeps engine gas compressible, heating services make it all run smoothly.
