Description

USA Lab 4" Falling Film Evaporator Turnkey System

The USA Lab 4" Falling Film Evaporator is engineered for high-throughput ethanol recovery with rapid evaporation and efficient heat transfer. Its controlled falling-film design creates a thin, uniform flow across heated surfaces to support fast solvent removal while helping minimize thermal exposure.

Designed for vacuum-assisted operation, the 4" Falling Film Evaporator provides controlled feed and heat-exchanger operation for consistent processing. The system can be configured as a Standalone evaporator, Pump Integration package, or complete Turnkey system with matched chiller and heater equipment.

The USA Lab 4" Falling Film Evaporator is designed for continuous-duty workflows requiring dependable ethanol recovery and controlled process conditions. Available pumping options include a 60 L/hr crude feed pump and 75–100 L/hr solvent recovery pump, with C1D1-rated options available for applicable installations.

4" Falling Film Evaporator Ethanol Recovery Vacuum-Assisted Operation Turnkey System

Thin-Film Efficiency: Uniform falling-film operation maximizes heat transfer and supports rapid solvent removal while helping reduce thermal exposure.

High-Throughput Recovery: Configurations support typical ethanol processing rates of 12, 14, 18, and 25 LPH, depending on operating conditions and system sizing.

24/7-Ready Design: Jacketed construction, VFD flow control, corrosion-resistant vacuum components, and continuous-duty pumping options support demanding workflows.

FAQ

What is the USA Lab 4" Falling Film Evaporator designed for?

The USA Lab 4" Falling Film Evaporator is designed for high-throughput ethanol recovery using vacuum-assisted falling-film evaporation. It provides controlled heat transfer and rapid solvent removal for demanding processing workflows.

What throughput can the 4" Falling Film Evaporator achieve?

Typical ethanol processing rates are 12, 14, 18, and 25 LPH, equivalent to approximately 3.2, 3.7, 4.7, and 6.6 GPH. Actual throughput depends on feed characteristics, viscosity, temperature, vacuum conditions, and utility sizing.

What is included with the different FFE-4 package options?

The Standalone package includes the 4" falling film evaporator body and frame. Pump Integration adds crude feed, solvent recovery, and vacuum pumps. The Turnkey package adds matched chiller and heater equipment for a more complete ready-to-run system.

Are C1D1-rated pump options available for the 4" Falling Film Evaporator?

Yes. C1D1-rated options are available for the crude feed and solvent recovery pumps. Verify local electrical, hazardous-location, ventilation, and installation requirements before commissioning the equipment.
