Yes, you heard it right. At Danfoss Cooling, We Love CO₂.
You might think that our devotion is misguided, but we can promise you that our affections are grounded in facts and modern engineering innovations. You see, despite its reputation as a pollutant, CO₂ is actually one of the most sustainable refrigerants. Unfortunately, it hasn't been possible to apply transcritical CO₂ systems in all climates – until now. Watch the video to find out why.

The High Pressure Ejector utilizes the energy in the high pressure gas to lift gas from the suction side (MT) moving it to the parallel compressors (IT). This provides a reduction in needed compressor capacity and energy consumption.
The Low Pressure Ejector recovers energy, otherwise lost in expansion, to lift the suction pressure. This reduces the consumption of the compressors.
The Liquid Ejector utilizes the energy in the high pressure gas to lift liquid from the suction accumulator. It works in combination with CO₂ Adaptive Liquid Management ensuring full evaporator optimization resulting in reduced energy consumption.
The Combi HP/LE combines benefit of the High Pressure Ejector and the Liquid Ejector, and giving you a complete solution with only one welding point needed during installation – making it even easier to get the benefits of CO₂.
The Multi Ejector family have recently been extended with 6 new types making it even easier to find a perfect fit for every store and system around the world.
The Danfoss family of Multi Ejectors now consist of the following members:
We have collected all our products and solutions for CO2 and equipped each with a unique code number for easy reference, you can now explore our CO2 solutions effortlessly.

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.
AK-PC 782A is complete regulating units for capacity control of compressors and condensers in a transcritical CO2 booster system with parallel compressor.
AK-CC55 is designed with user experience in focus, resulting in bigger connectors and AK-CC55 Connect app. The AK-CC55 platform consist of 4 controllers. AK-CC55 Compact is a standard case controller for TXV/EEV. AK-CC55 Single Coil/UI is an advanced case controller for EEV with adaptive algorithms. AK-CC55 Multi Coil is an advanced case controller controlling from 1 to 3 EEV’s in same refrigeration section.
The Danfoss AK-System Manager (AK-SM) is a modern solution for the food retail markets. The AK-SM uses the latest technology to provide the maximum benefit to the end user, both in terms of energy saving optimization, control options and user friendly access.
There are three main factors to consider when designing your transcritical CO2 system with a Multi Ejector Solution™.
