Heat pipe scheme
Heat pipes are essential components for providing effective thermal management in various industrial systems.
A heat pipe is a closed tube which contains a fluid (often a liquid with a low boiling temperature) circulating between its two ends depending on temperature differences. They make it possible to maintain a uniform temperature, thus meeting the requirements of the most complex applications.
We mainly deal with three types of heat pipes, each designed for specific uses:
- Melt lines: Ideal for plastic transfer.
- Cylinders: Used for various applications, such as the production of plastic films.
- Bells -: These heat pipes use stainless steel screen technology, ensuring even heat distribution and protection against temperature variations.
Thermal shrouds
We use various quality materials and techniques to guarantee the performance and durability of our thermal shrouds:
- Stainless steel 304L, 316L 316 Ti… These stainless steels offer excellent resistance to corrosion and heat.
- Nickel alloys Used for spot-welded screens, these alloys are renowned for their strength and resistance to extreme temperatures.
- Copper for screens with brazing Possibility of creating stainless steel accessories for specific applications.
We specialize in point-welded stamped screens, also using other types of welding such as TIG. Our stainless steelthermal shrouds, comprising spot welded elements and tubes brazed to sheets, are versatile protection systems. They are used to protect equipment exposed to extreme conditions, such as the multi-million degree plasma flow in the Tore Supra. They are also suitable for simulating environments in sectors such as space. These screens are also used in our air/water exchangers and in our heat pipe activities, using advanced welding technologies.

Screen-fin exchangers
Our screen-fin heat exchangers are designed to efficiently transfer thermal power between a gas and a fluid.
These exchangers are particularly suitable for cooling systems, such as air cooling with water for electrical cabinets, for example.
- Stamped Plates and Crushed Tubes – For the fluid circuit, we use stamped plates or crushed stainless steel tubes, ensuring excellent heat transfer. Stamped plates are preferred due to their better thermal performance.
- Bonded Aluminum Fins For the gas circuit, the fins are made of 1050 aluminum and bonded with thermal glue, thus improving heat transfer between the plates and the fins.

Fin-fin exchangers
Our fin-to-fin heat exchangers operate efficiently over a wide temperature range and are suitable for various industrial uses. They are ideal for gas-to-gas applications.
Materials Aluminum: Used for the fins, this material ensures excellent thermal transfer and increased durability.
Thermal Adhesive: Used in bonded technology to improve heat transfer between fins.
Bonded Technology – The exchangers use 1050 aluminum fins, bonded with thermal glue to improve heat transfer.
Vacuum Brazed Technology – This method is mainly used if the temperature is below 100°C.
