COOLING TOWER APPLICATIONS
Water Cooled Models Only
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 rejected, and
the pressure drop through the condenser and water valves
(inlet to outlet) when using a cooling tower on an ice
machine.
• Water entering the condenser must not exceed 90°F
(32.2°C).
• Water flow through the condenser must not exceed 5
gallons (19 liters) per minute.
• Allow for a pressure drop of 7 psig (.48 bar) between
the condenser water inlet and the outlet of the ice
machine.
• Water exiting the condenser must not exceed 110°F
(43.3°C).
