Section 8. How Do Air and Water Temperatures Affect My Commercial Ice Machine?

Comparing Ice Machines with Temperature Standards

 

Once you know your average daily ice production requirements, you will have to select a machine that can keep up with that need.

When looking at the manufacturer’s specification sheet you will see an approximate number of pounds of ice produced per 24 hours.  Many times the production rate will be provided for ideal conditions of 70 degrees F for the surrounding air and 50 degrees F for the incoming water supply.

Other manufacturers rate their equipment at 90 degrees F Air and 70 degrees F water supply, making comparisons of ice machine models from different manufacturers nearly impossible to calculate. Machines may seem similar in most respects but their ice production rates are the key factor in determining if the unit is right for your application. Even if you think you have found a machine with the right ice production rate, your air and water temperatures may differ, thus making it difficult to determine if the machine is appropriate for meeting your needs.

To help standardize the production rates for comparing from machine to machine or manufacturer to manufacturer, production rates are also determined by the Air-conditioning and Refrigerating Institute (AHRI), an independent organization that tests ice machines.  AHRI laboratories use controlled conditions of 90 degrees F Air and 70 degrees F Water to test the machines, duplicating the environment of a typical restaurant kitchen and creating a standard.

Always consult the current AHRI rating, but keep in mind your typical surrounding air and incoming water temperatures.  Different climates will affect the rate of ice production of an ice machine.  The temperature of the working environment where the ice machine will be placed can affect the volume and quality of ice produced.  If your location or climate is excessively hot, you should consider increasing the size of the ice machine to ensure that you are meeting your daily production requirements.

AHRI Certification

 

Manufacturers voluntarily subject their equipment to the AHRI Certification testing process. When a customer can see that the equipment has been rated by an external trustworthy source such as AHRI, they can confidently compare apples to apples, so to speak, since all ratings are conducted through standardized testing procedures. Individual manufacturers may have their own production rates for a specific ice machine models, making it difficult to assess which manufacturer's unit will produce enough ice for your application. However, when you compare two brands of ice machine that seem to be the same size, you can compare the AHRI production rates and know which manufacturer's model makes more ice.

Look for the AHRI Certification symbol on manufacturer's specification sheets and equipment labels.

Note that all old ARI Certfication symbols have been updated and replaced on current equipment with the New AHRI Certification logo.
