Corrosion Resistant Non-Metallic Heat Exchanger

In some applications, corrosive fluids are present that cannot be tolerated by metal equipment. In those cases, heat exchangers manufactured from either impervious graphite or silicon carbide can offer not only a viable but reliable solution. We have world leading technology in corrosion proof equipment. We will work with you to engineer a solution you can trust.

Block-Type

This equipment consists of drilled blocks made from graphite or silicon carbide typically stacked together with gaskets in-between to provide the necessary surface area.  

Graphite (Graphilor®)

  • Large heat transfer areas (up to 300 m2)
  • Large range of block sizes from 140 to 1,500 mm diameter
  • Design for high pressure up to 16 bar (service side) and 12 bar (process side)
  • Headers – available in Graphilor®, stainless steel, reactive metals, PTFE or rubber lined steel
  • Multi-pass arrangements possible for both process and service sides

Silicon Carbide (Polybloc®)

  • Resistant to temperatures of nearly 1000°C
  • Universal anticorrosive solution
  • Pressure resistance up to 40 bars
  • High thermal shock resistance compared to graphite and glass-lined
