Danfoss has released its new Large CO2 Ejector with one of the biggest capacities in the world.
The new Ejector overcomes concerns about system efficiency, particularly at high ambient temperatures, which has traditionally been a barrier to CO2 adoption in industrial settings.
The new Large CO2 Ejector from Danfoss is made for industrial-sized refrigeration and heat pump systems reducing energy consumption, even in warm climates.
The Large CO2 Ejector provides a number of features that can improve the efficiency of industrial CO2 systems, resulting in cost savings including:
Dedicated and user-friendly driver (EKE 80) for flexible integration with any PLC controller
- Integrated functionality, with the check valve and filter integrated into the solution
- Fixed geometry design, enabling higher control and efficiency
- User-friendly design with housing and cartridge delivered separately for easy installation
- 140-bar (2030 PSI) pressure rating makes the ejector a good fit for transcritical CO2 systems in most climates, including warm climates
Serving as a main expansion valve in industrial racks above 500 kW, the Large CO2 Ejector offers work recovery capabilities at the gas cooler outlet.
It can be used with industrial racks with high pressure (HP) or low pressure (LP) lift systems.
The HP lift version leverages high-pressure gas energy to move gas from the suction side to parallel compressors, reducing the required compressor capacity and overall energy consumption.
Alternatively, the LP lift version recovers energy typically lost during expansion to increase suction pressure. This process lowers the energy consumption of the compressors. Both configurations enhance system efficiency by optimising energy usage within the refrigeration cycle.
Danfoss business development manager, Dean Groff, said with ejectors of this capacity, large CO2 systems become more efficient and easier to design.
“By making CO2 a more attractive option for the industrial refrigeration industry and increasing its adoption, the Large CO2 Ejector reflects Danfoss’ goal of helping the industry lower its carbon footprint and meet sustainability goals,” he said.
