Refrigeration Energy Monitor – EnerG²


Designed by the Madison Energy Group, EnerG2 is a remarkable retrofit device that reduces the energy consumption of commercial grade coolers and freezers. Most coolers and freezers measure the temperature of the air, which can fluctuate in a matter of seconds. This is the reason that you generally hear the compressor turn on whenever you walk in to your freezer. When you place your temperature probe into the EnerG2 module, it mimics the density of a food or beverage. Because food or drink doesn’t heat up as quick as air, the temperature probe will not read the small changes in the air temperature. This reduces the number of times that the compressor will turn on..

Benefits of the EnerG2

What can EnerG2 do for my business?

Save you money!

Walk-in refrigerators use up to 60% more compressor cycles than needed, which results in a 15% to 30% waste of energy. EnerG2 cuts down on these unnecessary cycles resulting in lower the number of cycles by 40% to 60%. After installing the EnerG2 module, you will save an estimated 20% to 30% of the electricity consumed by your freezer or cooler. An added benefit of the EnerG2 is the reduced maintenance cost of your compressor as you will be removing stress and reducing its cycle rate. EnerG2 is low cost and results in big savings, which leads to a short return on investment.

EnerG2 is endorsed by the Green Restaurant Association (GRA) because of its ability to conserve energy, reduce CO2 emissions by thousands of pounds annually, and accurately measure the temperature of food and beverage, thus increasing food safety.

Not only will you save money, but the EnerG2 module has no electrical or mechanical assembly and therefore can be installed in minutes. On top of all this, it comes with a 10-year warranty.

In Good Company

But don’t take our word for it: companies such as McDonald’s, Dairy Queen, and Panera Bread, and theme parks such as Universal Orlando and Walt Disney World’s resorts all use the EnerG2, to powerful results.

In addition to these testimonials we offer a complimentary two-week data logging program. We will log one week of energy consumption with your compressor as is, then we will install the EnerG2 module and log another week. You will see for yourself the savings you can expect and at no cost to you!
