Reflux Divider – Automatically Operated (MAGNETICALLY)
This type of reflux divider uses a swinging funnel mechanism. The funnel, which has a soft iron core sealed into it, is operated magnetically from outside the column, so that the condensate can be removed from the column and reflux returned to the column in correct ratio. Activation of the electro-magnet moves the funnel into the off-take position. The electro-magnet and timer should be ordered separately. Main nozzle (DN2) is provided for ARHM 9 and above sizes.

Reflux Divider Automatically Operated (Magnetically)

Electro – Magnet
Electro-magnet is used to operate magnetically operated Reflux dividers. When ‘On’ the magnet attracts the swinging funnel of the reflux divider so that distillate can be taken off.


Electro-magnets are to be mounted outside the glass column, just near to the reflux divider, with the help of adjustable fittings. This is designed to use with Timers to maintain correct ration between ‘Off’ and ‘On’ timings of its activation.

Electro-magnet work on 220V DC power supply, for which an output socket is provided in the Timer.

Electro Magnet

Timer is designed to use with Electro-magnets to provide a correct ratio of reflux and distillate when operating a Magnetically operated reflux divider.


Two independent knobs are provided for time settings of Reflux and Off-take. During ‘Offtake’ it activates the electro-magnet, which attracts the swinging funnel of reflux divider, and distillation comes out. Both periods can be set accurately within a range of 0-50 seconds.

Timer work on a power supply of 230V, 50Hz.
