Reflux Divider
Precision reflux dividers for controlling reflux ratios in distillation columns.
Reflux Divider Overview
Reflux dividers are used to take off the distillate from a column, with a valve usually fitted on the distillate outlet for coarse control of reflux. They are available in standard and magnetically operated designs. In the standard type, DN2 is used for inserting a thermometer pocket, while a bellow is recommended on the distillate outlet DN1. In the magnetically operated type, the swinging funnel mechanism is controlled by an external electro-magnet and timer, enabling accurate reflux ratio control. The funnel stays at 100% reflux when the magnet is inactive. Liquid seals are used on magnetically operated dividers to prevent vapour from bypassing directly to the receiver.

Applications
Reflux dividers and their accessories are commonly used in:
• Distillation columns for chemical and pharmaceutical industries
• Research laboratories for precise reflux ratio control
• Pilot plants and production facilities requiring reflux management
• Processes needing accurate separation, distillate collection, and reflux return
• Systems where thermometer pockets are required for temperature monitoring
• Installations requiring vapour-tight operation using liquid seals
