The North Star Capacity Calculator

North Star provides a quick and easy way to determine the correct North Star ice maker model for your application. Our capacity calculator takes information about your capacity requirements and operating conditions and recommends the correct North Star model. Using this tool, you can also request a quote on the recommended ice maker.

The calculator provides general guidance on North Star models, but there are a number of factors that can be adjusted for maximum capacity and particular applications. North Star can assist in reviewing your specifications and providing advice for your project. Please contact us for more information.

TIPS FOR USING THE NORTH STAR CAPACITY CALCULATOR

Calculation Type:	The default is set for US Standard calculations. If you would prefer metric, click the button for Metric.
Freezing Surface:	Stainless steel refers to standard stainless, Plus and Elite models. Stainless steel freezing surface is recommended for all food-related ice making or for seawater ice. Carbon steel can be used for non-food applications. For more information go to Which Freezing Surface?
Ice Required:	Select the amount of ice you need for each 24 hour period. For more information go to How Much Ice?
EvaporatorTemperature:	Evaporator temperatures will vary according to your refrigerant type. If using ammonia the evaporator temperature could go as low as -35°F (-37°C). Freon could range from -15°F to -25°F (-26°C to -32°C), for its lowest evaporator temperature. Nominal capacities are based on -25°F (-32°C) evaporator temperature.
Ice thickness:	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.
Refrigerant Type:	North Star ice makers will work with any standard refrigerant.
Water SupplyTemperature:	The recommended incoming water temperature for most applications is 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 water.
Find Recommended Model:	When all conditions are selected, click here for your recommended model. You can continue to change the conditions and re-select this button at any time to update your calculations.
