Description

Automatic, reflux control via solenoid valve arrangement. Reflux control is effected by an adjustable time switch and solenoid takeoff valve. Reflux ratio is a time function and independent of throughput except when a single drop is a significant part of the condensate. Viscous liquids cause no difficulty. Temperature measurement is by means of a thermocouple or 7/12 jointed thermometer, 40 mm immersion located in the vapor stream. Vapor velocity prevents reflux from running down the well. Joints are 14/20. Supplied with thermometer.
