Q: “Whatʼs inside eCube®?”
A: eCube® contains a patented, high molecular weight, aliphatic hydrocarbon compound. The substance is inert, non-toxic, and approved by the NSF for usage with any refrigerator or freezer.


Q: “How do I know this is safe for my product?”  
A: eCube® was actually invented as a food safety device, and it was only accidentally discovered that it saves energy as well. eCube®  is NSF certified as a food safety device and there is an NSF logo on every eCube® sold, so customers can feel comfortable that their product is at least as safe (or even safer) than it was before. In NSF studies, the eCube® actually achieved a more consistent product temperature over time (i.e., less fluctuations).


Q: “How does eCube® know what type of product is in the case?”
A: How does a thermostat know whether it contains hot or cold liquid? Itʼs the same principle. eCube® does not “know” what is in the case, it simply insulates the probe with a patented compound that is similar to most foods. In other words, there is much less of a difference between the thermodynamic properties of “eCube® vs. product,” than there is between the thermodynamic properties of “air vs. product.”


Q: “Will installing eCube® void my warranty?”

A: No. Manufacturers warranty is for defects in materials or workmanship, neither of which are affected by eCube®. eCube® has no mechanical or electrical parts and is therefore “non-invasive” to the refrigeration system. There is functionally no difference between installing an eCube® and changing the usage pattern of the cooler or freezer.

Q: “We already have a food monitoring system...”

A: There are some stand-alone food monitoring systems that allow customers to drop a device into a case that transmits food temperature back to a monitoring system. The important thing to focus on is that eCube® also does that but pays for itself. So, eCube® is a self-financing food monitoring system, which puts it way ahead of the competition.


Q: “How does this work with an evaporator system?”

A: By simply substituting the existing evaporator thermostat with an inexpensive air thermostat, eCube® can deliver the same energy and equipment savings in an evaporator system.


Q: “How does this work with a pressure system?”

A: It can work with a pressure system, if they have thermostats in the cases and reconfigure the system to regulate refrigeration supply based on changes in eCube® temperature. Alternatively, it can simply be used as a food monitoring system, sending product temperature back to their IT systems for each case or zone.


Q: “How does eCube® affect the temperature inside the refrigerator or freezer?”

A: eCube® actually lowers the air ("case") temperature due to more efficient cooling and, to compensate for this new lower temperature, the thermostat setting is adjusted upward. In other words, eCube® achieves the same air temperature with a higher set point, thus saving energy.


Q: “How does eCube® affect the outside temperature gauge?”

A: eCube® lowers the inside air temperature and, therefore, the temperature reflected on the outside gauge. The temperature on the display will also be more accurate as it will not be as influenced by warm air rushing into the case from an open door just before the inspection.


Q: “How much energy will eCube® save?”

A: There are several factors that contribute to the total energy saved per device.  Some of these factors include location of the air probe, age of refrigeration unit, insulation, etc.  With an eCube® installed trails have shown a savings of 10% to 30% or more.   


Q: “Do electronic delays built into refrigeration units do what eCube® does?”

A: No.  They serve two entirely different functions.  Electronic delays are designed to protect the microprocessor while the air probe continues to monitor the ambient temperature.  Electronic delays do not affect the compressor cycling patterns, which is how eCube® ultimately delivers energy savings. 


Q: “How can an eCube® mimick different types of food?”

A: eCube® does not mimic specific foods; rather the food simulant substance inside eCube® is designed to take on general thermal properties of food. eCube® is more efficient at maintaining food at consistent and desirable temperatures than a system that monitors ambient air temperature. 


Q: “Does eCube® meet FDA regulations for health inspection?”

A: Absolutely.  Health inspectors typically probe foods inside refrigeration units to determine food core temperature.  Since eCube® regulates core food temperature more accurately and consistently, the inspections will meet FDA guidelines for food safety. 


Q: “What is NSF and why is it important?”

A: NSF International is an independent, not-for-profit organization that helps to protect consumers by certifying products and writing standards for food, water and consumer goods.  NSF’s ongoing public health commitment is to encourage everyone to live safer.  For more information on NSF visit www.nsf.org.
