On this type of reflux separator, a valve is fitted to the outlet pipe. When it is open the condensate flows only through the product off-take connection, but it can be partially or fully closed so that some or all of the condensate returns to the column as reflux giving coarse reflux control.

Reflux Separators - Automatically Operated
In applications where there is need for the reflux to be at a fixed value, then it is advisable to fit an electro-magnetically or pneumatically operated reflux separator in conjunction with a timer.
Reflux Separators - Magnetically Operated
This type of reflux separator 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 electromagnet moves the funnel into the off-take position. The electromagnet (shown dotted) and timer should be ordered separately. Details can be found below.
