Process Heating for the Aerospace Industry

Industry Challenges

The aerospace industry presents some unique challenges for process heating, including:

  1. Process heating systems must be able to heat and circulate air under extreme conditions, including high temperatures and pressures.
  2. There are strict and demanding regulations that the aerospace industry is subject to. These regulations place limits on the types of materials that can be used in heating systems.
  3. Heating systems for the aerospace industry must accommodate a wide range of flows, temperatures, and pressures. This often leads to the need for custom-engineered solutions that can be costly and time-consuming to develop.
  4. Components and systems used in the aerospace industry must be able to adapt to rapid changes in process conditions.


At Sigma Thermal, we offer process heating systems and fuel gas conditioning solutions that address the challenges of the aerospace industry.

Process Heating Systems

Process heating systems heat air and circulate it at tightly controlled temperatures to various process streams. In the aerospace industry, process heating systems are used to heat and circulate air in turbine systems while ensuring highly controlled temperatures and optimal efficiency. Sigma Thermal offers quality process heating solutions that offer the following benefits:

  • Optimized combustion efficiency. By carefully controlling the heat and airflow, engineers can ensure that each aircraft engine operates at peak efficiency.
  • Equipment longevity. By evenly distributing heat throughout an engine or fuselage, process heating helps to avoid hot spots that can cause premature metal fatigue.

Fuel Gas Conditioning Solutions

The main function of a fuel gas conditioning system is to keep the gas stream free of impurities that can cause problems downstream, such as failure, damage, or poor performance. These systems ensure that the gas is always in compliance and of the highest quality. At Sigma Thermal, we can provide quality fuel gas conditioning solutions that can meet your needs while providing various benefits such as:

  • Improved combustion system performance
  • Longevity of turbine combustion systems
  • Decreased emissions
  • Impurity-free gas streams
