Finalised a few months ago, Barajas became the first of 37 Makro stores in Spain (Madrid) equipped with a refrigeration system using only CO2 as a refrigerant.
Food retailers, refrigeration system and component manufacturers and contractors highlight advantages of natural refrigerants, particularly R744, over traditional HFC systems in commercial refrigeration, including energy consumption reductions, total system integration and reduced environmental impact.
House of Spices (HOS) has ticked off a number of milestones in its 44-year history producing and distributing authentic Indian cuisine throughout the U.S. At its Chicago warehouse, the company recently achieved another rare feat, installing one of the few existing industrial CO2 transcritical refrigerant systems in North America, with the help of Hillphoenix.
Edeka Kusenberg is equipped with a transcritical CO2 refrigeration system with heat reclaim and innovative freezers to save energy and enhance the shopping experience.
Exclusive interview with Danfoss suggests CO2 technology can bring new opportunities for retailers in China
At China Refrigeration 2015, R744.com interviewed Zhaohui (Stephen) Zhu, Sales Director for Food Retail in China about the opportunities and challenges CO2 technology represents for commercial refrigeration in China.

In addition to featuring a number of low-charge ammonia products, the IARW-WFLO Convention & Expo, held in Orlando, Florida on 26 – 19 April, included several exhibitors promoting CO2-only and ammonia/CO2 refrigeration systems. While CO2 is still relatively new for the refrigerated warehouse operators attending the show, it is slowly gaining traction as an alternative to traditional high-charge ammonia systems.
Carrefour has big plans for CO2. The company won’t go so far as to declare an all-CO2 philosophy, yet its expansion into warmer ambient climates, in particular two transcritical pilot stores in Valencia, would suggest that notion is closer to reality than they might think. R744.com sat down with the Director International Support at Carrefour, Jean-Michel Fleury, about the expanding CO2 transcritical market in Europe.
SONAE MC’s Amad Hafez spoke to R744.com about their experience with cascade systems in Portugal and the retailer’s feelings about their future use of natural refrigerants. While the company praised the high savings their CO2 subcritical commercial refrigeration systems were able to provide, they are still seeking an alternative to R134a. The performance of its two CO2/NH3 stores has not met expectations. However, SONAE MC is keeping an eye on CO2
With CO2 transcritical retail stores in warmer European climates expected to hit 100 in the next two to five years thanks to technology developments like adiabatic cooling, ejectors and parallel compression, Bulgaria represents a potential growth market for the technology. Although there are still barriers to overcome in the EU Member State positive developments are on the way with leading retailer Kaufland seriously considering CO2-only systems.
A motivation to transform industry perception of CO2 as a refrigerant was behind Hillphoenix’s decision to supply the first transcritical CO2 ice rink installation in the U.S.
