exchanger, if possible. If eliminating single-pass cooling is not feasible, consider reus-
ing the cooling water for another application. See
Section 8: Onsite Alternative Water
for more information.
When replacing an ice machine or installing a new one, ensure that the new model
is sized appropriately to fit the facility’s need. If the machine produces too large of
a yield, water will be wasted by producing unnecessary ice. Choose an ice machine
that is appropriate for the quality of ice needed. Producing ice of higher quality than
required will use water unnecessarily. Look for ENERGY STAR qualified models,
which are air-cooled. Also consider air- or water-cooled ice machines that meet the
efficiency specifications outlined by the Consortium for Energy Efficiency.
consider selecting air-cooled flake or nugget ice machines, which use less water and
energy than cubed ice machines.
A facility will see varying levels of water savings, depending upon whether it is re-
placing an existing air-cooled ice machine or an existing water-cooled model.
The Food Service Technology Center has a life cycle and energy cost calculator, which
can be used to calculate the savings potential from replacing many types of commer-
cial kitchen equipment, including commercial ice machines.
To estimate facility-specific water savings and payback, the facility can also use the

ENERGY STAR qualified ice machines are, on average, 15 percent more energy-
efficient and 10 percent more water-efficient than standard air-cooled models. Total
savings depend upon the type of machine selected.
