The "E-Cube"

Reading refrigeration blogs today has been very fruitful.  Looking at Today's Facility Manager blog I came across an amazing little invention.  Claiming use in the UK for several years and now being marketed in the US, this little itty bitty plastic box with wax in the middle supposedly can help increase your refrigeration's efficiency by 20%.
E-Cube's site (which ironically is also an Ubercart site [a shopping cart software developed from Drupal  by a company in our building] ) boasts that their invention will reduce compressor cycles by 50% and uses 15-30% less energy.
How does it work you ask?
Well, the box attaches onto the thermometer of your unit, which measures air temperature (highly volatile and unstable according to them) and not the actual food temperature.  The E-Cube uses a wax substance which imitates food at 15mm below the food surface.  Inside the wax is a thermostatic unit which then measures the temperature of the wax, hence replicating the temperature of the food instead of the air around the food.  It is available in 3 sizes so that it can fit most models.
For more information, visit their site.  But if you're looking for energy saving tips for your Walk-In Coolers or True equipment , this could be a solution for you.  One article states that you can get your investment back in as little as 2 years (maybe shorter).  It comes with a 5 year warranty and a 60 day 100% Money Back Guarantee.  Sounds like we around here need to try one of these!

Stay Chill more efficiently with the E-Cube.
