Product Overview
-
The FDG-J Series is a high-performance pilot-scale fractional distillation system designed for process scale-up, pilot trials, and small-batch production.
-
With capacities from 1 L to 200 L, this fractional distillation equipment combines pilot-scale processing capability with laboratory-level precision. Its jacketed heating system, customizable column configurations, and flexible vacuum or atmospheric operation make it suitable for different fractional separation requirements.

Key Features
-
Jacketed Heating System: Features a fluid-circulating jacket for uniform heating, RT to 250℃ (usually ≤200℃).
-
Modular Fractionating Column: Standard column diameters (30/35/40mm) and 1m height, customizable lengths available.
-
Packing Versatility: Compatible with θ-rings, Raschig rings, structured packings, and other advanced fillings.
-
Flexible Distillation Setup: Supports both atmospheric and vacuum distillation (≤50Pa), suitable for heat-sensitive materials (e.g., vitamins, essential oils).
-
High Chemical Compatibility: Borosilicate 3.3 glass + PTFE components withstand acids/alkalies/organic solvents
-
Visual Process Monitoring: Visual Process Monitoring: The transparent borosilicate glass design allows real-time observation of vapor-liquid flow and packing conditions during the fractional distillation process.
-
Efficient Mixing: High-torque AC motor with PTFE impellers and digital speed control prevents bumping.
-
Easy Cleaning: Discharge valve with no-dead-space design ensures no residue.
