Northstar Ice

Calculation Type  
Freezing Surface:
Ice making capacity required per 24 hour US tons
Evaporator Temperature: °F
Ice thickness: mm
Refrigerant Type:
Water Supply Temperature: °F

Approximate capacity calculations are based on +/- 2% machine capacity. Actual ice maker output will vary based on customer provided refrigeration, freezing surface condition and supply water temperature and quality inputs.

For additional information about how to use the calculator, please see our calculator tips. Please note that the calculator provides only general recommendations. If you have specific requirements or need help, contact North Star.

The default is set for US Standard calculations. If you would prefer metric, click the button for Metric.

Stainless steel refers to all three North Star stainless steel models; the Standard, Plus and Elite ice makers. Stainless steel freezing surfaces are recommended for all food-related ice making or for seawater ice. Carbon steel can be used for non-food applications.

This will vary according to your refrigerant type. If using ammonia the evaporation temperature could go as low as -35°F (-37°C). Freon could range from -15°F (-26°C) to -25° (-32°C) at the low range. Nominal capacities are based on -25°F (-32°C) evaporator temperature.

1.5mm is recommended for fastest heat transfer (cooling) and highest capacity. 2.0 to 2.5mm is recommended for ice that will be conveyed pneumatically or stored for long periods before use.

North Star ice makers will work with any standard refrigerant.

The recommended incoming water temperature for most applications is approximately 60°F (15.5°C). Concrete cooling applications require 40°F (4.4°C) water. For higher incoming water temperatures, it may be more cost-effective to add a water chiller to pre-cool the supply water so the refrigeration capacity of the ice maker will be used for ice making, not for chilling the water.
