The key to any modern thermal energy system is the ability to transfer heat – at the required temperature, at the required time.  All exchangers are produced to the highest quality standards, ensuring a long, reliable and safe working life. A wide range of exchangers are currently produced as standard variants, covering all applications within the modern thermal energy field.



  • highly turbulent flow behaviour
  • optimal self cleaning effect
  • highest possible heat transfer
  • high-grade materials


  • high heat transfer coefficient
