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:
Three main factors to consider when designing your transcritical CO2 system with a Multi Ejector Solution™.

Danfoss has pioneered two control algorithms that help you achieve this balance. The Minimum Stable Superheat (MSS) algorithm has been an important part of the Danfoss ADAP-KOOL® offering for years and is still the ideal choice for adaptive evaporator control for dry expansion. Now Danfoss introduces the next generation: Adaptive Liquid Control (ALC).
Intelligent control solutions are important for achieving reliable, optimized operation and realizing financial savings and environmental benefits in your transcritical CO2 refrigeration solution.
