FRP Evaporators

FRP evaporators concentrate solutions by heat or vacuum evaporation. They use FRP vessels and heat-transfer surfaces to handle corrosive feeds (e.g., salt brine, acid). Often used in serial batches or continuous systems for chemical concentration.

Key Features

  • Corrosion-Resistant Heat Jackets: FRP shells with FRP or metal heating coils.
  • Vacuum Capability: Closed FRP vessels that can operate under partial vacuum to lower boiling points.
  • Drain & Sludge Handling: Designed for easy removal of concentrated solids.

Benefits

  • Safe Concentration: FRP resists scaling and acid that would damage steel.
  • Energy Efficiency: Vacuum operation reduces required heat.

Applications

  • Chemical Processing: Salt, caustic recovery, acid concentration in chemical plants.
  • Pharmaceuticals: Solvent recovery under low-heat conditions.

Technical Specifications

  • Capacity: Customizable, such as 100 to 1000 L batches or continuous flow.
  • Materials: FRP (vinyl ester) for the shell; stainless steel or FRP for coils.
  • Vacuum Rating: Down to –0.8 bar for lower-temperature operation.

Unique Selling Points

  • Tailored Systems: Complete FRP evaporator assemblies, including heat source and condensers.
  • Minimal Scale Formation: Smooth FRP surfaces reduce scaling, lowering downtime.
