# Techeat expansion range

Control your combustion through better sealing of your installation with the new Techeat expansion® range.

Some critical zones like manhole, inspection hatch, crossover inlet, coil outlet…need to be properly sealed to limit unwanted air in the furnaces. These actions will have a direct and immediate impact on your operating cost and will decrease the atmospheric emissions.

Techeat Expansion C54

Techeat Expansion® C.54

- 1 fastening point : oven casing
- Sliding type seal
Techeat Expansion S21

Techeat Expansion® S.21

- 2 fastening points : Oven casing & tube
- Bellow type seal

For most of them various solutions exists and are in place but regarding the crossover inlet/ coil outlet the constraints of tube radial and axial expansion as well as thermal (150°c up to 1200°c), are to be taken in consideration.

The Techeat Expansion® range is dedicated to those mechanical/thermic constraints and is easy-to-fit without training.  
Our technical team will study your specific application on site in order to propose you the best dedicated solution.
