Danfoss is proud to announce that their BOCK HGX56 CO2 T compressor was named the winner in the Refrigeration category of the 2025 AHR Expo Innovation Awards.
The annual awards competition honors the most inventive and original products, systems, and technologies that will be showcased at this coming January’s International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) in the categories of building automation; cooling; sustainable solutions; heating; indoor air quality; plumbing; refrigeration; software; tools & instruments; and ventilation.
Latest Danfoss innovation for refrigeration
Supporting customers in their transition to low-GWP refrigerants is a key priority for Danfoss
Supporting customers in their transition to low-GWP refrigerants is a key priority for Danfoss. The company’s dedication to environmental responsibility drives the continuous development of efficient and reliable CO2 compressors that guarantee peak plant efficiency while minimizing investment, energy, and operating costs.
The BOCK HGX56 CO2 T, the latest Danfoss innovation for sustainable refrigeration, is a transcritical semi-hermetic CO2 (R744) compressor, ideal for industrial refrigeration, cold storage, ice sports facilities and heat pumps.
benefits of the increased capacity
The expansion to 6-cylinder capacity allows for a wider spread and faster uptake of large CO2 heat pumps and industrial refrigeration systems, along with lower system complexity and investment costs.
Additional benefits of the increased capacity–up to 135 kW for cooling and 360 kW for heating – include greater efficiency and reliability, along with low noise and vibration, a compact and lightweight design, and a minimal oil carry-over rate.
Larger refrigeration and heat pump applications
The new 6-cylinder design ensures greater capacities while reducing the number of compressors
The new 6-cylinder design ensures greater capacities while reducing the number of compressors. With its high efficiency and reliability, this innovation enables larger refrigeration and heat pump applications with less footprint and strong energy-efficient performance.
As a result, the HGX56 CO2 T is an attractive alternative to compressors using HFC or HFO refrigerants or ammonia and provides the same optimal performance at full and partial loads.
requirements of the global phasedown of F-gases
The product is circularity-oriented as it is easy to service and replace all components and fulfills the requirements of the global phasedown of F-gases.
“The BOCK HGX56 CO2 T compressor represents a breakthrough for industrial and commercial refrigeration and large-capacity CO2 heat pumps, including process and district heating applications,” said Vikas Anand, vice president of sales, Danfoss Climate Solutions, North America.
Carbon emissions and energy consumption
Anand added: “With the push to decarbonize heating and refrigeration, the BOCK HGX56 CO2 T enables customers to reduce both carbon emissions and energy consumption without sacrificing performance. We are honored to be recognized by AHR Expo.”
Winners of the AHR Expo Innovation Awards program are selected by a panel of third-party ASHRAE member judges who evaluate all award entries based on innovative design, creativity, application, value, and market impact.
