CTR 3-way heat reclaim valve is designed to allow full proportional control of the surplus heat from compressor pack into the heat exchanger of transcritical heat reclaim solutions, securing availability of heat and hot water. The CTR valve prevents pressure peaks eliminating costly system down-time and the risk of insufficient heat supply for store heating and hot water, regardless of installation size.
The CCMT is an electric operated valve designed specifically for operation in CO2 systems. The valve is capable of functioning either as an expansion valve, as a pressure regulator for the gas cooler or as a gas bypass valve with back-pressure regulation in trans-critical or subcritical applications.
The system manager is the key component of the intelligent Danfoss ADAP-KOOL® refrigeration system for food retail.
The Danfoss Multi Ejector Solution™ ensures that transcritical CO₂ applications for retailers become energy efficient in any climate.
Refrigeration pressure transmitters are used for commercial air-conditioning and for commercial and industrial refrigeration applications. They are made in stainless steel to be compatible with fluorinated and natural refrigerants and laser welding with no soft seals ensure hermetic tightness for decades.

Case studies
Globus had an ambitious target: to open the new 25,000 square meter hypermarket using transcritical CO2 for its refrigeration and heating. Danfoss helped KrioFrost—a Moscow-based refrigeration equipment producer and installer—to equip Globus’ huge new store in the Moscow suburb of Salaryevo with the company’s first transcritical CO2 booster refrigeration system.
The supermarket aktiv & irma in Oldenburg, Germany, has pressed the start-button to a solution enabling it to store and generate electricity. The grocery store’s manager calls it a leap forward in energy supply. Danfoss and SMA have helped make it happen. Learn how.
The use of transcritical CO₂ refrigeration in warm climates has been a hot topic for years. In Milan, the brand new 10,000 m² Iper market is a pioneer in CO₂ refrigeration using ejector technology to enhance efficiency in temperatures up to 38 °C.
The F-gas regulation in Europe and similar legislation in other parts of the world push for low-GWP solutions in food retail refrigeration
All over the world, the phase-down of conventional HFCs in food retail applications has become the center of attention in the effort to combat climate change. Most recently, at the meetings of the parties under the Montreal protocol in Dubai where qualitative global phase-down of HFCs was agreed with a target of quantifying the details in 2016.
In this article, we will explore the pros and cons of different solutions for CO₂ refrigeration in warmer climates – from basic cascade systems to the advanced ejector technology.
