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 approved 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). 

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.” 

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.

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. 

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. 

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.

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.

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.

The Frigitek does not interfere with the refrigeration cycle nor directly control the compressor, thus it cannot harm the compressor or any of the other equipment. 
Because operation of the Frigitek causes the compressor duty cycle to be reduced, it can only have a beneficial effect on the equipment and should extend its life accordingly.
 

The Frigitek follows the thermostat's cycling of the system to control the speed of the fans in the evaporator coils, and does not directly affect any other portion of the refrigeration system. 
The refrigeration system continues to function normally.
