Worldwide training in CO₂ refrigeration
CO₂ is emerging as the go-to solution in the food retail market as traditional HFCs are phased out and retailers look for new ways to reduce their carbon footprint. Danfoss launched the Mobile CO₂ Training Unit in September 2016 to provide easy-to-access, hands-on training for the thousands of installers, service technicians, and OEM engineers worldwide that want to take full advantage of the natural refrigerant.
The Mobile CO₂ Training Unit makes both the technology and understanding of CO₂ refrigeration immediately available to industry professionals. Danfoss CO₂ experts will present CO₂ systems and solutions, which include simple gas-bypass systems as well as more complex parallel compression solutions, with or without heat reclaim. They will also introduce our new Multi Ejector Solution™ that can enhance the energy efficiency of systems by up to 20% on the hottest day of the year, enabling the use of trans critical CO₂ systems in much harsher climates.
Learn more about:
- Trans critical system design: simple booster system, parallel compression, parallel compression with ejector
- Commissioning of CO₂ systems
- Set up of pack and case controls
- Service procedures
- Troubleshooting and correction
