CTA Architecs together with retailer SUPERVALU talkabout the opening of their first complete natural refrigeration store in US. Through application of original technologies and innovations with the natural refrigerants ammonia, carbon dioxide, and propane, an industry influencing solution is available. An on‐site comparison is made between the ammonia primary system and a redundant R407A primary system. The result from this comparison allows SUPERVALU and the industry to understand the achievable balance of Total Equivalent Warming Impact (TEWI), equipment and operating costs, maintenance considerations, and repeatability.
