Mechanical Vapor Compression (MVC) Evaporator

The ENCON MVC Evaporator product line has standard offerings that range in capacity from 40-1800 gallons/hour. These systems operate on electricity and compressed air at a typical operating cost of $0.01-$0.02* per gallon of distilled water. Materials of construction include 316 Stainless Steel and Super Stainless alloys for more corrosive waste streams.
 * Assumes electricity cost of $0.10/kW-h

The ENCON MVC Evaporator is highly automated with minimal need for manpower intervention. Automation includes: wastewater feed, automatic discharge of concentrated residue from the Separation Tank, automatic transfer of distillate from the distillate sump, and automatic cleaning (Clean-in-Place) of heat exchangers. Numerous variables such as temperature, pressure, and water level are monitored continuously, and will trigger various alarm conditions that notify the operator of deviation from normal operating mode.

The ENCON MVC product line is defined by capacity and alloy based nomenclature as referenced in the tables below.

For example, the ENCON model MVC300-366-26B-A1 is a 300 gallon/hour system with separation tank, recirculation loop piping, and main heat exchanger constructed with super stainless alloy.
