Training on solar cooling technologies for agricultural value chains

Target groups: Solar technicians, cooling technicians, entrepreneurs

Intro: SelfChill is a concept for modular cooling solutions powered by solar. As core components SelfChill Cooling Units are used for the construction of a wide variety of cooling systems. A lot of material for the construction of the systems can be sourced locally.  Therefore the SelfChill concept enables local manufacturers, installers or entrepreneurs to construct cooling systems  locally and adapt the systems according to the needs of the final end-users. SelfChill cooling systems can be small- to medium-scale milk coolers, cold rooms or ice makers.
