Through installations, training and industry initiatives, contractor Source Refrigeration – led by its chief engineer Bryan Beitler – is helping food retailers and others transition to natural refrigerants
By Michael Garry
At that time, Source, based in Anaheim, Calif., had just begun to install CO2 refrigeration (mostly pumped systems using HFCs on the high side). Since then, Source has gone on to deploy many more CO2 systems, including cascade and transcritical, for a total exceeding 50 – likely the most of any U.S. contractor. As Heath noted, the company has committed itself to teaching its technicians about the art and science of natural refrigerants, staking out an industry-leading position in the training arena.
The individual who has orchestrated Source’s natural refrigerant activities is Bryan Beitler, its On July 25, 2012, Supervalu unveiled the first all-natural-refrigerant system in the U.S. at a remodeled store in Carpinteria, Calif.
The cascade refrigeration system employs ammonia on the rooftop and CO2 in the store.
This was the first time that only ammonia and CO2 were used in a U.S. supermarket’s refrigeration system (the first all-CO2 transcritical system would come a year later); today there are three more U.S. stores with this cascade system.
Now owned by Albertsons, the Carpinteria store represented a turning point for natural refrigerants in the U.S. Many parties played important roles in this installation, including Supervalu and the manufacturers Hillphoenix (provider of the CO2 rack) and Mayekawa (supplier of the ammonia rack).
