WATERCOOLED CONDENSER WATER PRESSURE
Water pressure at the condenser cannot exceed 150 psig
(1034 kPa) with the standard water-regulating valve.
Contact your distributor if your water pressure is greater
than 150 psig (1034 kPa). A special order condenser/water-
regulating valve is available that allows water pressure up
to 350 psig (2413 kPa).
Important
The Commonwealth of Massachusetts requires that
all water-cooled models must be connected only to a
closed loop, cooling tower system.
COOLING TOWER APPLICATIONS WATERCOOLED
MODELS
A water cooling tower installation does not require
modification of the ice machine. The water regulator valve
for the condenser continues to control the refrigeration
discharge pressure.
It is necessary to know the amount of heat rejection and
the pressure drop through the condenser and water valves
(inlet and outlet) when using a cooling tower on an ice
machine.
• Water entering the condenser must not exceed 90°F
(32°C).
• Water flow through the condenser must not exceed 5
gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psi (50 kPa) between the
condenser water inlet and the outlet of the ice machine.
• Water exiting the condenser must not exceed 110°F
(43°C).
