Wuxi Yiteng Pressure Vessel Co., Ltd. designs and manufactures customized Short Path Distillation Equipment for high purity separation and molecular purification applications.
Short path distillation is an advanced vacuum separation technology designed for materials requiring:
✓ Extremely low evaporation temperature
✓ High purity separation
✓ Minimal thermal exposure
✓ High recovery efficiency
✓ Continuous processing capability
The system is especially suitable for valuable heat-sensitive compounds where conventional distillation methods cannot achieve desired results.
Core Structure:Internal condenser at center
Operating Pressure:Ultra-high vacuum 0.001 mbar
Viscosity:Low, limited by rotor design
Internal Condenser
● Installed at cylinder center, shell-and-tube or coil type
● Forms fixed short-path evaporation gap with outer heating cylinder
● Core component for capturing and condensing light molecules
● Condenser area: 1.5~3.5 times evaporation area
● Head-type bottom design for dead-space-free discharging
● 15° inclined plates between cylinders for smooth heavy component discharge
● Optional jacket or coil insulation for high-viscosity post-evaporation conditions
Technical Description
Key Advantages:Highest purity, lowest temp, minimal degradation

Short Path Distillation operates under deep vacuum conditions.
The material flows down the heated evaporation surface and forms a thin film.
Process:
The extremely short vapor path minimizes pressure loss and thermal exposure.
