THE EFFECT OF TEMPERATURE ON ICE PRODUCTION
WATER TEMPERATURES
Seawater and freshwater temperatures affect the ice machine’s efficiency and capacity. The system is most efficient when the
seawater and fresh water temperatures are 55-80°F (13-27°C). The ideal temperature for both is 70°F (21.1°C). See Figure 3.
High Temperatures - As water temperatures approach 90°F (32°C) and above, the water’s ability to absorb heat diminishes, so
the capacity of the system decreases. Also, when seawater temperature increases above 90°F (32°C), the system could sustain
a high-pressure shutdown to protect the compressor.
Low Temperatures - As water temperatures approach 45°F (7.2°C) and below, the water’s ability to provide heat exchange
diminishes, so the capacity of the system decreases. Also, as the water temperature decreases, the system could sustain a low-
pressure shutdown to protect the compressor.
AIR TEMPERATURE
The Effect of Ambient Air Temperature
The ambient air temperature affects the ice machine’s efficiency and capacity, but not as significantly as the water
temperatures. The system is most efficient when the ambient air temperature is 55-80°F (13-27°C). At temperatures above and
below this range, ice production will decrease. See Figure 3.
CAUTION
Extreme care should be taken in operating any unit below seawater temperatures of 45°F (7.2°C). The
seawater could freeze in the condenser tubing, possibly causing it to burst, which is not covered by the
warranty.
