General information

  • Doubling of energy prices within 8 years 
  • The use of previously unused exhaust gas streams becomes increasingly important
  • A heat exchanger prototype provides valuable information on design and subsequent operation at unspecified exhaust gas conditions 
  • Optimisation of material, for example P235GH // 1.4301 // 1.4571 //1.4462 // 1.4539 // 1.4529 // 2.4605 // ect.
  • Optimisation of operating parameters (return temperature)
