Spiral heat exchanger
Spiral heat exchangers are manufactured using two metal plates wound together leaving two parallel channels where fluids can flow in a counter-current direction.

They offer excellent thermal approaches but are best suited for high fouling fluids like slurries or fluids containing fibrous material.

  • Best suited for fluids with high solid contents (i.e. slurries)
  • Constructed of steel or stainless steel
  • Shell diameter up to 2m
  • Spiral width up to 1.5m
  • Spiral spacing 8 – 45mm
  • Surface area to 500m2
  • Typical Applications
  • Refineries
  • Biogas
  • Waste water
  • Pulp and paper
