The heat exchanger specialist

Shell and tube heat exchanger

Shell and tube heat exchangers are designed and manufactured in France to meet diverse energy needs with duties up to over 70 MW.

Shell and tube heat exchanger


  • Made in France, custom design
  • Over 80 years of expertise, know-how recognized by integrators
  • We master complex applications: high pressures, rare materials…
  • Exclusive know-how: the Shell & Twist® twisted tubular heat exchanger, bitubes and multitubes exchangers
  • All the international quality certifications

Heat exchanger shell & tube

We provide tubular heat exchanger solutions suited to a wide range of operating conditions: heat exchangers with up to 3 meters in diameter, under vacuum or pressure up to 400 bar, manufactured from steel or other materials (stainless steel, copper alloys, titanium, etc.)…
