Water Supply and Drain Line Sizing/Connections
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
condensing unit is available that allows water pressure
up to 350 psig (2413 kPa)
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).
