Multi Ejector Solution™

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
Danfoss CO₂ Adaptive Liquid Management

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.
