Content of the training

Content of the training

The overall objective of the Cool Training initiative is to spread in-depth knowledge and the capacity to operate and maintain cooling technologies based on natural refrigerants. Participants can learn about the use of propane (R290) and CO2 (R744) in commercial refrigeration systems, as well as Ammonia (R717), which is addressed briefly. The training includes two visits to innovative German companies, such as natural refrigerant producers, RAC component manufacturers and refrigeration plants. It heavily emphasises hands-on practical sessions (70% practice, 30% theory), creating expertise that can be applied immediately in the participant's line of work.

For technicians:

Practical and theoretical content includes: safety and environmental requirements according to DIN EN 378-1:2017-03 to 4:2017- 03; the application of propane (R290) and CO2 (R744) as refrigerants; the recovery of R134a and its replacement with R290 in RAC appliances; refrigerant circuit pipe joining and installation methods; leak finding and tightness test activities in practice.

For NOU representatives:

Furthermore, a one-week Cool Training course has been developed for policymakers and stakeholders working on the topic of natural refrigerants and the protection of the ozone layer and climate. Participants receive a certificate of completion after finishing the training and passing the written examination. Proklima encourages alumni to act as knowledge multipliers in their home countries and regions.

The training is conducted in cooperation with the Bundesfachschule Klima-Kälte-Technik (BFS), one of the leading German vocational training centres for refrigeration technology with more than fifty years of experience.

"The experience was mind-blowing! Overall, the information was vital and could help me improve RAC on my small island."

Benefits and fees


Demand for natural refrigerants is rising rapidly. The growth is driven by recent national, regional and international politico-legal developments, such as the EU F-Gas Regulation and the Kigali Amendment. The training courses help RAC experts and trainers gain a competitive edge over their peers by staying up-to-date and working in accordance with current regulations and standards, while at the same time moving away from unsustainable technologies and refrigerants, such as HFOs and HFCs (e.g. R134a). Alumni can use their expertise to help environmentally-conscious consumers and industries to meet their green cooling objectives, while helping the national government meet its Nationally Determined Contributions – the national climate change mitigation commitments under the Paris Agreement.

Expertise and organisation

GIZ Proklima is a programme of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. It has been providing technical assistance to developing countries since 1996. Under commission of the Federal Ministry for Economic Cooperation and Development (BMZ), GIZ helps in the implementation of the provisions of the Montreal Protocol on substances that deplete the ozone layer. Proklima launched the Cool Training series in 2014. Since then, more than 300 trainers, lecturers, and representatives of National Ozone Units (NOU) and implementing agencies have been officially cool-trained. The training is implemented in cooperation with Bundesfachschule Klima-Kälte-Technik (BFS), one of Germany’s leading vocational training centres for cooling technology with more than fifty years of experience.
