SFI electric heaters are fast, stable, and reduce undesirable byproducts in high-speed Wind Tunnel applications.


Compact, Efficient, Quick and Precise

Tutco SureHeat builds high-temperature electric heaters for wind tunnel applications. Our Specialty Flanged Inline (SFI) electric heaters are fast, stable, and reduce undesirable byproducts.

  • Ramp to temperature in seconds
  • Achieve 1,800F, 2,000F, and above
  • Maintain operating temperature stability
  • Significantly reduce contaminants over arc and gas heaters
  • Smaller footprint compared to other technologies

Tutco SureHeat SFI heaters are well suited for supersonic and hypersonic blowdown test facilities. If you’re upgrading an existing wind tunnel and require higher and more stable temperatures, contact us and tell us about your project.
