Heat exchanger manufacturer

Worldwide heat exchanger leader with solution-oriented approach

For decades, Mersen has designed and manufactured a comprehensive portfolio of heat exchangers using various technologies (blocs, tubes) and the materials (graphite, SiC, tantalum, zirconium, titanium). These heat exchangers can be installed as condensers, heaters, coolers...in the corrosive chemical processes..

Thermal design experience to define your project requirements

Mersen has been recognized as an expert in thermal and mechanical design for all types of heat exchangers (condenser, evaporator, boiler…) with proven design tools allowing the most thermally efficient calculations : ASPEN B-JAC, X-Designer, In-house programs..

Highly skilled and experienced Engineering Department

With more than 450 mechanical designs completed each year, our highly experienced Engineering Staff provides drawing and mechanical design support using various software tools to produce the calculations required by the current pressure vessel design codes (ASME, EN 13445, CODAP, AD 2000 Merckblatt) and ANSYS for the specific Finite Element Analysis.

Worldwide production sites and local service centres

We can also provide support for all the products we deliver throughout their life cycle and offer a broad range of services. After-sales service can be carried out at our Mersen sites or directly on the customer's site :

  • Maintenance and spare parts supply, including repair and refurbishment services
  • Immediate emergency assistance & Start-up services 
  • Process lines check-up and diagnosis
