Glycol-Cooled DualCool
Normally, heat is transferred to
a flow of chilled water (by others).
DualCool units include a three-
way proportional chilled-water
valve, balanced bypass line, flow
switch and water-temperature
sensor. All are factory mounted
to copper piping for a standard
working-pressure rating of 400
psig (2758kPa), ideal for high-rise
buildings.
The unit is rated for use with
45°F (7.2°C) chilled water. For
flow rates and other details, see

If the flow rate or temperature of the
chilled water becomes inadequate for
proper operation, the unit will automatical-

Expansion.
