Action hubs


Capacity building plays a key role in the uptake of new technologies, and sustainable cooling is no exception. Cool Up’s holistic approach to upscaling sustainable cooling supports technical skills training.

Together with Master Trainers from Centro Studi Galileo, we offered training on safe handling of natural refrigerants, bringing together 15 experts from our action hubs in the MENA region and Türkiye. The training covered a broad range of topics, including:

  • Background on natural refrigerants
  • Creating a safe work environment
  • Working safely with a variety of natural refrigerants
  • Hazard analysis
  • Operating conditions
  • Reducing leak potential and improving resilience
  • Installation and commissioning of R744 systems
  • Service and repair
  • Flammable refrigerants
  • Cylinders, storage, handling 
  • Compressor changing procedures
  • Flammability versus GWP
  • Repair of refrigeration equipment with flammable refrigerants
  • and more
Congratulations to all of our participants for working so hard on their theoretical and practical skills, and for receiving their REAL Alternatives certification & Cool Up Certificate of Participation.
