Redefining CO2 compressor racks with EmJ
ELECTRONIC MODULATING EJECTOR

CAREL’s continuous research has led to the development of centralised systems with ejectors, making it possible to use CO2 systems more efficiently even in warmer climates and extending the use of CO2 technologies to more regions of the world.

The ideal solution for all store formats, without compromise in terms of energy efficiency and environmental impact.

CAREL’s continuous research has led to the development of centralised systems with ejectors, making it possible to use CO2 systems more efficiently even in warmer climates and extending the use of CO2 technologies to more regions of the world.

The ideal solution for both small and large stores, without compromise in terms of energy efficiency and environmental impact.

  • Natural refrigerants (CO2)
  • Suitable for all installation sizes 
  • Reduced energy consumption 
  • Control stability and excellent food preservation 
  • Easy installation and commissioning ensured by a fully totally integrated system

 

 

EmJ - Electronic Modulating Ejector

EmJ - Electronic Modulating Ejector

The CAREL multiplex system with Electronic Modulating Ejector is the solution that guarantees the environmental benefits of using CO2 in medium and large supermarkets while also benefiting from the energy advantages of a transcritical system with ejector.

New frontier in efficiency
The ejector, combined with a parallel compressor, recovers part of the system’s energy, thus boosting efficiency.

Simple connectivity
Using Carel controllers, the system maintains a stable product temperature at all times, together with total control of the installation thanks to a fully integrated system.
