There has been scant data in the literature about the energy savings that can be realized from condenser coil cleaning of plug-in cooling appliances …. until now:
New energy savings data was disclosed last month in an educational presentation at the RFMA (Restaurant Facility Managers Association) Convention in San Diego, CA: Condenser coil cleaning was performed on a 6 year old, 2-door glass merchandiser. Such cleaning produced a 47% reduction in both electric usage and cost (or about $625 per UNIT). (A non-cleaned unit consumed 24.19 kWh/yr at a cost of $1325/yr. The cleaned unit needed 12.76 kWh/yr and cost only $700/yr to run.)
At the CFESA Spring 2015 Spring Conference on Feb. 18, a presentation was given about how preventative maintenance can pay off and gave savings data of about $260 and $440 for coil cleaning a single door freezer and double door refrigerator, respectively. It so happens that the % energy savings were about the same, 47% and 50%, as for the data previously described.
Additionally, an excellent description of the possible, major repair costs persons may face if they neglect this cleaning has also been recently published.
They have developed the unique COILPOD dust hood allowing this cleaning to be done on commercial-type units in a “green”/no-mess manner with compressed air and vacuum.
They are a 2014 PRSM best practices technology and have just been featured as the “App of the Month” in this month’s Foodservice Equipment Reports (see http://bit.ly/1wg1ERl).
Here’s a link to the COILPOD demo video: https://www.youtube.com/watch?v=PPKQFq4vqzA. Our website (www.coilpod.com) has more information plus an online store for retail purchase of bag(s), e.g. for a pilot testing program.
