WATER - (For Condensers)

Water-cooled condensers are designed to operate
with a water/propylene glycol solution, supplied
at a temperature of 41°F to 118°F (7.2°C to
47.8°C). A minimum of 10 percent propylene glycol
by weight is recommended. If water piping is run
outdoors, 35 percent propylene glycol by weight
will give burst protection, (not freeze protection),
to approximately –40°F (–40°C). Regardless of the
amount of propylene glycol, it must be ensured that
the water loop has adequate corrosion inhibitors.
The water flow requirements for each case are:
