Supermarket refrigeration is entering one of its biggest transition periods in decades. New US refrigerant regulations, rising electricity costs and growing demand for fresh and frozen foods are pushing grocery retailers to modernise their cooling infrastructure. Major supermarket chains are replacing legacy systems with lower-emission technologies, particularly carbon dioxide (CO₂) and propane-based refrigeration, while investing in monitoring platforms that reduce maintenance costs and food waste.
For equipment suppliers, the shift is creating new opportunities and new competition. Manufacturers that can deliver energy-efficient systems, natural refrigerants and nationwide service capabilities are increasingly becoming strategic partners to grocery retailers. From refrigerated display cases to compressors and system controls, a relatively small group of companies now plays an outsized role in keeping America’s supermarket shelves cold.

1. Hussmann Corporation
Founded: 1906
Headquarters: Bridgeton, Missouri
FY Revenue: Private company
Few names carry more weight in supermarket refrigeration than Hussmann. The company has spent more than a century supplying refrigerated display cases, walk-in coolers and integrated refrigeration systems to food retailers across North America.
Its product portfolio covers almost every department inside a supermarket, from produce and dairy to frozen food and convenience sections. In recent years, Hussmann has significantly expanded its natural refrigerant offering, particularly CO₂ transcritical systems that help retailers reduce emissions and comply with evolving regulations.
The company also benefits from a nationwide service network, giving major grocery chains a single supplier for equipment, installation and maintenance.
2. Hillphoenix
Founded: 1887
Headquarters: Conyers, Georgia
FY Revenue: Private company
Hillphoenix has become one of the industry’s leaders in natural refrigerant technology. The company was among the early adopters of transcritical CO₂ systems and has built a strong position with supermarkets looking to reduce reliance on traditional hydrofluorocarbon refrigerants.
Its equipment is widely used in large-format grocery stores, regional chains and new store developments.
Beyond manufacturing display cases and rack systems, Hillphoenix has invested heavily in controls and integrated energy management, areas that have become increasingly important as supermarkets seek lower operating costs.
3. Copeland
Founded: Independent company since 2023
Headquarters: St. Louis, Missouri
FY Revenue: Private company
Copeland is one of the most important companies in supermarket refrigeration, even though consumers rarely see its name.
The company manufactures compressors, electronic controls and monitoring systems that sit behind many of the industry’s refrigeration installations.
Following Emerson’s complete exit from the climate technologies business in 2024, Copeland emerged as an independent company focused entirely on refrigeration and HVAC technologies.
Its products play a critical role in improving system efficiency, reducing energy consumption and supporting the transition to lower-emission refrigerants.
4. CoolSys
Founded: 2019
Headquarters: Brea, California
FY Revenue: Private company
CoolSys occupies a different position in the market. Rather than manufacturing refrigeration equipment, it specialises in installing, servicing and maintaining supermarket refrigeration systems.
The company has rapidly expanded through acquisitions and now operates one of the largest refrigeration service networks in the United States.
For supermarket operators, the ability to maintain equipment efficiently is becoming as important as purchasing the equipment itself. Downtime can result in product losses, food safety risks and higher energy costs.
5. Dover Corporation
Founded: 1955
Headquarters: Downers Grove, Illinois
FY Revenue: Approximately $7.75 billion
Dover’s importance in supermarket refrigeration comes through its ownership of several businesses serving food retailers, including Hillphoenix and Anthony International.
The industrial conglomerate has steadily built a portfolio of refrigeration and food retail technologies that extends from display cases to merchandising solutions.
Its scale gives it the financial resources to invest in product development and energy-efficient technologies at a time when supermarkets are accelerating capital spending on refrigeration upgrades.
6. Zero Zone
Founded: 1961
Headquarters: North Prairie, Wisconsin
FY Revenue: Private company
Zero Zone has developed a strong reputation for energy-efficient refrigeration systems and is particularly well known for its work with CO₂ technology.
The company supplies refrigerated display cases and integrated systems to supermarkets across the country and has been an active participant in the industry’s move toward natural refrigerants.
Its systems are frequently selected by retailers seeking to lower energy consumption and reduce their environmental footprint.
7. Heatcraft Refrigeration Products
Founded: 1946
Headquarters: Stone Mountain, Georgia
FY Revenue: Private company
Heatcraft is one of the largest suppliers of condensing units, evaporators and refrigeration components in North America.
While consumers are unfamiliar with the brand, its products are widely used behind supermarket refrigeration systems and cold storage operations.
The company’s broad product range and established distribution network have made it a longstanding supplier to contractors and grocery retailers.
8. True Manufacturing
Founded: 1945
Headquarters: O’Fallon, Missouri
FY Revenue: Private company
True Manufacturing is best known for its commercial refrigeration cabinets and display equipment.
The company has become increasingly active in propane-based refrigeration technologies, particularly self-contained R290 systems that offer lower environmental impact compared with traditional refrigerants.
Its products are commonly found in supermarket deli departments, convenience sections and prepared food areas.
9. Kysor Warren
Founded: 1882
Headquarters: Columbus, Georgia
FY Revenue: Private company
Kysor Warren remains one of the largest US manufacturers dedicated to supermarket display cases and refrigeration systems.
The company has invested heavily in CO₂ technologies and integrated system designs, helping retailers comply with changing environmental regulations while improving energy performance.
Its long history in food retail refrigeration gives it a strong position with regional and independent supermarket chains.
10. Anthony International
Founded: 1958
Headquarters: Sylmar, California
FY Revenue: Private company
Anthony International occupies a specialised niche within supermarket refrigeration.
The company manufactures glass doors and merchandising systems used on refrigerated display cases across North America.
As supermarkets focus more on energy efficiency, high-performance glass doors and lighting systems have become increasingly important in reducing electricity consumption and improving product visibility.
Industry Outlook
The refrigeration industry is now being shaped by three major trends.
The first is the transition to natural refrigerants, particularly carbon dioxide and propane systems.
The second is energy management. Supermarkets are under pressure to lower operating costs, and refrigeration remains one of the largest sources of electricity consumption inside a store.
The third is system intelligence. Retailers are increasingly investing in remote monitoring, predictive maintenance and digital controls to reduce service costs and prevent equipment failures.
Manufacturers that combine equipment, software and service capabilities are likely to gain a larger share of future supermarket investment.
What Happens Next?
