Ice Production Check
The amount of ice a machine produces directly relates
to the operating water and air temperatures. This
means an ice machine with a 20°C outdoor ambient
temperature and 10.0°C water produces more ice than
the same model ice machine with a 32°C outdoor
ambient and 21°C water.
1. Determine the ice machine operating conditions:
Air temp entering condenser: ____°
Air temp around ice machine: ____°
Water temp entering sump trough: ____°
2. Refer to the appropriate 24-Hour Ice Production
Chart.
3. Use the operating conditions determined in Step 1
to find published 24 hr. ice production: ____
• Times are in minutes.
Example: 1 min., 15 sec. converts to 1.25 min.
(15 seconds ÷ 60 seconds = .25 minutes)
• Weights are in grams.
4. Perform an ice production check using the formula
below.
Weighing the ice is the only 100% accurate check.
Compare the results of Step 3 with Step 2. Ice
production is normal when these numbers match
closely. If they match closely, determine if:
• Another ice machine is required.
Relocating the existing equipment to lower the load
conditions is required.
