Description
USA Lab 4" Falling Film Evaporator Turnkey System | USA Lab
Engineered for high-throughput ethanol recovery, the USA Lab 4" Falling Film Evaporator delivers rapid evaporation with minimal thermal degradation. A controlled thin film flows over heated surfaces for maximum heat transfer, efficient solvent removal, and consistent product quality across botanical, pharmaceutical, and chemical workflows.
With vacuum-assisted operation, metered injection, and precise heat-exchanger control, operators can tune temperature and feed rates for their crude characteristics and target viscosity. Choose from Standalone, Pump Integration, or a complete Turnkey package with matched chiller/heater for ready-to-run performance.
Note: Unit is designed for ethanol. Please contact sales for uses with other solvents Safety: C1D1-rated pump options available; verify local compliance before commissioning.
4" Evaporator Body High Throughput (LPH/GPH) Vacuum-Assisted Recovery Turnkey Packages
Thin-Film Efficiency: Uniform falling film maximizes heat transfer and minimizes thermal degradation.
C1D1 Pumping Options: Crude feed (60 L/hr) and solvent recovery (75–100 L/hr) for continuous duty.
24/7-Ready Design: Jacketed body, VFD flow control, corrosion-resistant vacuum path, and steady uptime.

Why this 4" falling film evaporator?
- Optimized ethanol recovery — fast solvent removal from ethanol-diluted crude under controlled vacuum.
- Package tiers — Standalone (body/frame), Pump Integration (adds crude/solvent/vacuum pumps), or Turnkey (adds matched chiller & heater).
- C1D1 readiness — explosion-proof pump options with leak-free continuous operation.
- Precision control — VFD-driven feed, tuned heat exchangers, and metered injection for consistent film thickness.
- Built for uptime — jacketed design, 24/7 duty rating, and corrosion-resistant vacuum components.

FAQ
What distinguishes a falling film evaporator from other designs?
A thin, gravity-driven film flows down heated surfaces, delivering high heat-transfer coefficients and faster solvent removal with less thermal stress.
What throughput can the 4" FFE achieve?
Typical ethanol recovery rates are 12/14/18/25 LPH (≈ 3.2/3.7/4.7/6.6 GPH), depending on feed temp, viscosity, vacuum, and utility sizing.
Which pumps are included with each package?
Standalone: evaporator body/frame. Pump Integration: adds crude feed, solvent recovery, and vacuum pumps. Turnkey: adds matched heater/chiller for immediate operation.
Are the pumps C1D1 certified?
Yes. The crude feed pump (60 L/hr) and solvent recovery pump (75–100 L/hr) are available with C1D1 explosion-proof motors for hazardous locations.
Do I need additional adapters or utilities?
Fluid Jacket Adapters are not included. Ensure proper electrical service, heater/chiller capacity, and ventilation. Our team can help with pairing and site readiness.
