Discover why "We Love CO₂"
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.
Complete Multi Ejector portfolio for all store sizes, CO2 systems and climates
Danfoss offers a full range of Multi Ejectors – covering the needs for all store sizes, CO2 system and climates.
Multi Ejector - High pressure:
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.
- For CO2 refrigeration systems with parallel compression
- The best solution for warm climates
- Optimum for system sizing from 150 kW and up
Multi Ejector - Low Pressure:
The Low Pressure Ejector recovers energy, otherwise lost in expansion, to lift the suction pressure. This reduces the consumption of the compressors.
- For CO2 booster systems
- The best solution for warm climates
- Optimum for system sizing from 40-150 kW
Multi Ejector – Liquid Ejector:
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.
- For both CO2 booster systems and systems with parallel compression
- Efficient in both warm and cold climates
- Optimum for system sizing from 40-300 kW
CO₂ Adaptive Liquid Management
The new CO2 Adaptive Liquid Management (CALM) solution from Danfoss extends the portfolio of solutions for CO2 refrigeration in food retail applications. CALM includes the ground-breaking new Liquid Ejector in combination with the innovative case controller algorithm – Adaptive Liquid Control (ALC) – ensuring optimum liquid management. With CALM, the Danfoss CO2 portfolio offers solutions for all system types, store sizes and climates.

Coolselector®2 features unbiased calculations for the selection of refrigeration and air conditioning components based on the user’s requirements or based on standard operating conditions.
The Danfoss Multi Ejector range for CO2 refrigeration: design, applications and benefits
Danfoss offers a complete portfolio of gas and liquid ejectors that provide significant benefits in CO2 refrigeration applications. Here we take a closer look at these offerings: the Multi Ejector Low Pressure (LP), the Multi Ejector High Pressure (HP), and the Liquid Ejector (LE). All three ejector products are only available as a complete Multi Ejector Solution™ where the ejector is bundled with the AK-PC 782A pack controller to provide the robust system controls necessary for efficient and reliable operation.
Selecting the right evaporator injection algorithm makes a world of difference
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).
Danfoss is proud to declare: “We love CO₂”, and with the Multi Ejector Solution™ you will too
CO2 is often regarded as the "big problem" when it comes to climate change. While in some regards it is a hazard, in other situations it can be the answer. In fact, when used as a refrigerant, CO2 can make a big difference when it comes to keeping people, products, and our planet cool.
