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

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 40-450 kW

Multi Ejector – Combi HP/LE:

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.

For CO₂ refrigeration systems with parallel compression
The best solution for warm climates
Optimum for system sizing from (40 to 105 kW)

Multi Ejector Solution – now with an extended family

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:

High Pressure – 3 types (150 kW and up)
Low Pressure – 2 types (40-150 kW)
Liquid Ejector – 5 types (40- 450 kW)
Combi HP/LE – 3 types (40 to 105 kW)
