green cooling initiative: Cool Training


GIZ Proklima Cool Training


GIZ Proklima Cool Training is a series of international trainings on the safe use of natural refrigerants in the refrigeration and air-conditioning (RAC) sector. Launched in 2014, these trainings have since supported the worldwide promotion of sustainable cooling technologies by providing training on the safe handling of natural refrigerants. Main target group are international RAC technicians and trainers as well as political decision makers from developing countries and emerging economies. Depending on the training program, the courses are offered as one-week or two-week packages aiming at NOU representatives and technicians, respectively.


The training objective is to spread comprehensive knowledge about and develop capacities for the operation and maintenance of cooling technology using natural refrigerants. Focus lays on the application of propane (R290) and CO2 (R744) in commercial refrigeration systems, while Ammonia (R717) is also addressed briefly. The training includes two company visits to innovative German enterprises, such as natural refrigerant producers, RAC component manufacturers and refrigeration plants. It heavily emphasizes hands-on practical sessions (70% practice, 30% theory) that can be applied right away in the participant's line of work. Contents covered in theory and practice are:

Safety and environmental requirements according to DIN EN 378-1:2017-03 to 4:2017- 03; Application of propane (R290) and CO2 (R744) as refrigerants; Recovery of R134a and replacement with R290 in RAC appliances; Refrigerant circuit pipes joining and installation methods; Leak finding and tightness test activities in practice.

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


Demand for natural refrigerants is rising rapidly and driven on 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 to gain a competitive edge over their peers by staying up-to-date on and working in accordance with current regulations and standards while at the same time leap-frogging 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, whilst supporting the national government with meeting their Nationally Determined Contributions, the national climate change mitigation commitments under the Paris Agreement.

Expertise and organization

GIZ Proklima is a programme of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. It provides technical assistance for developing countries since 1996, commissioned by the Federal Ministry for Economic Cooperation and Development (BMZ) to implement provisions of the Montreal Protocol on substances that deplete the ozone layer. Proklima launched the Cool Training series in 2014. Since then, more than 150 trainers, lecturers, and representatives of National Ozone Units (NOU) and implementing agencies have officially been cool-trained. The training is implemented in cooperation with Bundesfachschule Klima-Kälte-Technik (BFS), one of Germany’s leading vocational training centers for cooling technology with more than fifty years of experience.
