Food Service Equipment
Install an insulated dishwasher.
Replace a 10- to 20-year-old conventional dishwasher with an insulated model
and save up to $500 annually. Insulated tanks reduce stand-by or idle energy
consumption. A booster heater spends several hours per day consuming energy in
a "ready-to-use" mode. Insulated tanks can better maintain an
outgoing sanitizing water temperature at all times, thus, reducing stand-by
energy consumption.
Purchase insulated cooking equipment
whenever possible (e.g., fryers, ovens, coffee machines).
Insulation retains more heat in the equipment.
Replace conventional gas fryers with
infrared gas fryers or high-efficiency atmospheric gas fryers
and save up to $400/fryer annually.
Replace old, high-volume kitchen
sprayers with high-velocity, low-flow models, and save up to
$1,000 a year in hot water costs.
Refrigeration Equipment
Check temperature settings of
refrigerators. The most common recommended settings are between
-14 degrees and -8 degrees Fahrenheit for freezers and between 35 degrees and
38 degrees Fahrenheit for refrigerators.
Do not leave the walk-in refrigerator
door open when loading it. Install a plastic strip curtain over
the entrance and save up to $20 per refrigerator each year.
Perform scheduled maintenance on
refrigeration units. Keep evaporator coils clean and free of
ice buildup.
Buy an ENERGY STAR commercial solid
door refrigerator and freezer. Compared to standard models,
ENERGY STAR refrigerators and freezers can lead to energy savings of as much as
46% with a 1.3 year payback. Purchasers can expect to save $140 annually per
refrigerator and $100 per freezer.
Install energy-efficient case lighting.
T8 fluorescent lamps and electronic ballasts reduce lighting energy use and
reduce the cooling load on the compressor. Energy savings potential is 10% for
beverage merchandisers.
Install evaporative condensers, instead
of air-cooled condensers, to expel heat. Evaporative condensers
use a wetted filter that increases the ability to reject heat. Energy savings
range from 3 to 9% for grocery store refrigeration systems.
Install heat recovery systems to use
heat removed from display cases to heat water. A 7.5 horsepower
(hp) compressor can supply close to 100% of the hot water requirements in a
medium-sized grocery store all year long.
Install lighting sensors in walk-in
refrigerators. Install low temperature occupancy sensors or
timed switches in walk-in coolers and freezers to control lighting. Not only
does this save lighting energy, it reduces the load on the compressor. Save up
to $250/year.
Install pull-down blinds on open dairy
and produce cases. During non-operating hours, these blinds
keep refrigerated air from escaping.
