Every now and then, innovation requires simplicity and EnerG² is the perfect example of this with it simple concept yet effective function. EnerG² is a device that was developed by The Madison Energy Group and contains a non-toxic, food safe gel compound that has similar thermal properties to that of food and beverage.  It is therefore, not subject to the same wider and more volatile standard of deviation in temperature that ambient air is. 

The technology of EnerG² is based on the fact that food and beverage products contain significantly differently thermal properties than air.  This means that their temperatures rise and fall at different rates and at different intervals.  This causes inefficiency in operation because typical measurement is of the environment (air) and not the actual food and beverage product.  Air, having very little density, fluctuates with more volatility thereby causing the coolers to engage in cooling cycles unnecessarily, while EnerG² simulates the stable temperature curve of food product and allows the cooler to operate only when it needs to. This not only reduces energy consumption by 15-25% but also compressor cycles by 40-60%.

An innovative energy efficiency technology that is changing the way the hospitality industry cools food and beverage product.


EnerG² retrofits to the existing thermostat air probe in walk-in coolers and freezers and provides a more accurate means of temperature measurement by simulating food and beverage product (stable) in place of ambient air temperature (volatile).


In a world of better mousetraps, Madison Energy understands the needs and benefits of proving its technology better than anyone else. To that end, we have developed a single process that allows us to illustrate a side by side comparison of energy usage / savings that utilizes accurate measurement tools as well as 3rd party independent verification of data and reporting.
