I have a chill water system consisting of a main tertiary loop
feeding 2 dozen other branch tertiary loops. my problem is
in the chill rolls on the paper line. Control point is the exit
water temp. heated water is let out and replaced by chilled water.
Works fine while running at full speed. When line stops the
3-way valve closes and water is just circulated in the loop.
Which is cold enough to cause condensation, causing web
breaks at start up. Using an AB PLC 5/40 for control.
Any ideas???
