Falling Film Evaporators

Falling film evaporators are designed to separate alcohol and plant oils. Our line of falling film evaporators / separators feature:

  • Stainless steel and copper construction for easy cleaning / sanitizing.
  • Large sight-glasses for excellent viewing of alcohol and oil recovery as it is happening.
  • Pneumatically driven pumps and controls; less risk of electrical spark-based fire or explosion.
  • Automatic dumping of alcohol and oil; when a collection chamber fills it is automatically pumped to your storage container.
  • Compatible with all alcohols: ethanol, denatured ethanol, isopropyl, and methanol.
  • Small footprint; the ERU-300 liters-per-hour (80 gph) unit shown is 34 inches x 34 inches x 9′ 8″ tall.
