A recent European wide supermarket survey commissioned By Novum, found that heat generation was by far the number one reason which would discourage supermarkets moving from remote to plug-in refrigeration systems.

Why is heat rejection considered a problem with traditional plug-ins?

The simple equation “Energy in=Energy out” is applicable here, where the energy emitted from a plug in is directly correlated to the amount of energy required to run that freezer. In essence energy inefficient freezers emit more heat. You can witness this for yourself by putting your hands on the exterior walls of a traditional plug-in freezer when the compressor is running.

How is this potentially a problem for supermarkets?

If you have several traditional plug-in freezers running at the same time and you do not have an effective or no air conditioning system this can make the shopping experience in your frozen aisles uncomfortable for shoppers. This may affect their inclination to browse and linger in these aisles, to view the huge array of frozen produce you may have on offer. Consequently, frozen food sales may take a hit.

What is the solution if you want to install a simple, energy efficient, low CAPEX, minimal heat rejection refrigeration system?

The solution is LEAP™ technology. As mentioned earlier the heat rejection in a self-contained freezer is directly related to energy consumption. Through game changing LEAP™ technology Novum produces the most energy efficient freezers of their type on the global market, with the lowest levels of heat rejection on the market also.

For example, the Next Generation Grand Cayman freezer boasts 37% less heat rejection when compared to the next best in class competitor. The Panama Green upright has 1/3 of the heat rejection and energy consumption than similar sized competitor cabs.

This gives LEAP™ enabled freezers a distinct advantage as the heat rejection in most cases is virtually negligible (0.2 Kw average heat rejection for Novums largest LEAP™ enabled freezer)

The energy savings from Novum LEAP™ powered cases will more than compensate for minimal increases in air conditioning energy consumption in the warmer climates (Note: Colder climates have a bigger requirement to heat stores so there is even less of an increase in air conditioning energy consumption). Over 90% of Europes Frozen Food specialists have already converted to LEAP™ technology and are reaping the benefits as outlined above.
