Food Safety Test
To show how the Endocube would react under extreme conditions, we took two identical walk-in rooms and fitted one with an Endocube and leaving one exposed to fluctuating air temperatures. We then introduced hot food to both fridges in order to see how the fridge temperature would react. To ensure that it was tested to the limit, we raised the set point on the Endocube fitted unit to 40°F whilst the fridge without was set at 36°F. As you can see below, even though the Endocube fitted fridge was at a disadvantage, it actually managed to function as constantly as the fridge without.
These charts show an Endocube trial in the same units under normal conditions.
