Product Overview
The Gausin Rising Film Evaporator (RFE) operates with liquid and vapour flowing upward inside vertical tubes, creating a rising or climbing film on the tube walls driven by the vapour lift effect.
This configuration offers good heat transfer for low to medium viscosity feeds such as sugar solutions, caustic soda, and food liquors. It is not recommended for highly viscous or heavily scaling products.
Gausin RFE units are designed with optimized tube length (3 to 9 m), calibrated feed distribution, and vacuum systems for energy-efficient operation. Optional Thermo Vapour Recompressor (TVR) integration compresses effect vapour for reuse as heating steam, improving steam economy on multi-effect plants.
Rising Film
Liquid and vapour rise together for efficient heat and mass transfer.
Long Tubes
Tube lengths from 3 to 9 m for high evaporation rates per pass.
Low Hold-Up
Suitable for continuous concentration of clear process liquors.
Vapour Lift
Generated vapour assists liquid movement up the tubes.
Multi-Effect
Available in double and triple effect for steam savings.
Thermo Vapour Recompressor (TVR)
Optional TVR uses motive steam in a steam jet ejector to compress low-pressure vapour for reuse as heating medium, reducing live steam consumption.
Automated Control
PLC-based control of feed, vacuum, and product discharge.
