Evaporator control
KS 98 application

Description
For the production of nylon thread, the
raw material granulate in the extruder is
heated to approx. 270 °C by means of vaporized
Thermex (DIPHYL®) heat transfer
oil with a max. temperature deviation
of 1°C. The thermal oil is evaporated,
whereby the boiling point is kept constant
via the steam pressure.
The control equipment of the evaporator
regulates the heating power for the outflow
(product temperature). The working
point for the necessary heating energy is
determined from the difference between
outflow and return flow temperatures.
