Revolutionary MarvelGuarantees To Save You Up To 33%

On Your Refrigeration Electricity CostsWhile Prolonging The Life Of Your Equipment

There’s an on-going problem with the operation oftoday’s commercial refrigeration thermostats.Businesses, unknowingly, are spending more than

they need to for electricity and for shortened operationallife of hardware.

Here’s the untold story. When it comes to refrigerationof food products, temperature monitoring and control hasbeen dependent uponmeasurement of the air, not thefood itself. Air, which is a gas,warms and cools very quickly.This factor triggers your air-oriented cooling system tocycle often. However, solids and liquids, which havedramatically more mass or density than air, absorbtemperature change much more slowly. As a result, acooling system, oriented to actual food temperature, cyclesless frequently. Fewer cycle times translate into big savings.

Fortunately, you don’t need to replaceanything. There’s now a simple way tomodify how your thermostats function byreorienting them to monitor food insteadof air.

What is it and how does it work?The revolutionary add-on device,

called POWERCUBE, completelyisolates the temperature sensor from the airand, instead, encapsulates it with anengineered food simulant, so that the sensormonitors equivalent food temperature.

Refrigeration units work as a seriesof cycles. This automated activitymaintains the required storage temperature with alternatingstarts and stops. On/off air cycles typically run for aminimum of 12 cycles per hour and, in some open displaycases, up to 20 cycles per hour.

Today’s refrigeration units monitor circulating airtemperature in order to decide when to switch on and off.However, because air temperature naturally warms far morequickly than food temperature, these systems work harderthan necessary to maintain stored products at the righttemperature. This, in turn, leads to excessive electricityconsumption and undue wear and tear on your equipment.

Attention: Commercial Food Refrigeration Users With POWERCUBE in placeon your thermostat, your systemcan regulate according to thetemperature of yogurt or frozenmeat, for instance, instead ofthe temperature of air.POWERCUBE controlsthe compressor withincredible accuracy tosignificantly reduce thefrequency of costlyon/off cycles.

Here’s an analogy to the comparison of a “before”and “after” retrofit: Drive a car in the city for an hour,then drive the car on the interstate highway for an hour.

Either way, the driving timeis the same. The cityversion is filled with lots ofstop and go driving, a hotterengine, and low gas mileage

for a shorter distance. The interstate highway scenarioenables the car to run cooler and farther with fewerinterruptions and better gas mileage. The same holds truewhen using POWERCUBE. The compressor runs coolerwhile consuming fewer kilowatt-hours (kWh) ofelectricity by having fewer starts and stops. Most

compressors have a 4-to-1 ratio,meaning they draw four times

as much electricity instarting up in comparisonto continually running.Because start-ups use fourtimes more power (i.e.start-up usage of 16 amps,versus run usage of 4amps), considerable energysavings can be achieved.In addition, the moreefficient refrigeration cycle

leads to a more efficient unit,which then leads to a colder storage area. Consequently,the thermostat can be adjusted to a slightly higher set-pointtemperature for further substantial energy savings, withoutcompromising food safety, shelf-life, and quality.

Although the POWERCUBE cycles last longer, theirfrequency can be reduced by as much as 80%. Forexample, a Dairy Case air cycles 3 minutes on, 2 minutesoff, which equals 12 cycles per hour. With thePOWERCUBE fitted, the cycles change to 8 minutes on,7 minutes off, which equals just 4 cycles per hour. Thisequates to a 66.7% reduction in starts and an 11.1%reduction in total run time.

Refrigeration Energy CostIt’s all about the TEMPERATURE!

gives you a better way to control cooling duration levels and set-points!

The Value of Longer On-CyclesConventionally, thermostats start and stop compressors as temperature of air

changes between set-points. Since air temperature varies quickly, this generatesnumerous on/off cycles (typically 3-minute cycles), each individually without

having very much net cooling effect on the foodtemperature. However, with POWERCUBE fitted,

on-cycles typically run for 8 to 10 minutes,resulting in a positive food temperaturereduction, since the food is cooled moreeffectively. Longer cycles take advantageof the food’s thermal inertia. This leads tomore efficient use of the refrigerator

system, lower total run-time & energy consumption, and safer food.

The Value of Longer Off-CyclesWith POWERCUBE installed, longer off-cycles allow pressure equalization

between the high and low pressure parts of the refrigerant system. This results ina “softer” start from an overall cooler system, which keeps the compressor frombeing unnecessarily tripped by an unbalanced or high pressure status. In otherwords, low amperage clean starts obtain maximum efficiency more quickly, whichprovides more energy savings. Reliability and life span of all system componentsare enhanced with lowered power use. Over time, this also means fewer costlybreakdowns and service repairs.
