Materials & media

The choice of materials always depends on the type of application. We select only high-quality and durable materials to guarantee high process reliability as

well as a long service life of our systems.

For example, we use:

  • stainless steel
  • high-alloy stainless steels (1.4539, 1.4563, 1.4562, etc.)
  • Hastelloy®
  • steel (coated)
  • titanium

Depending on the media, the tanks and heat exchangers are provided with rubber coatings, PFA, E-CTFE or Blue Amor coatings, or lined with PVDF, graphite or PTFE. Heat exchangers are used impregnated with graphite or silicon carbide amongst others.
