Success story: Solar thermal cooling system for leading South African mobile operator

Subsectors: Chillers

Industrial Solar has installed a Fresnel Collector system for the leading South African mobile network operator Mobile Telecom Networks (MTN) in Johannesburg. The project falls under the global “Solar Roofs Program” which was launched by the Deutsche Energie-Agentur (dena) in 2004 and co-financed by the German Federal Ministry of Economics and Technology (BMWi). The goal of the Solar Roofs Program is to install demonstration projects on the roofs of designated institutions around the globe. Comprehensive marketing and training programs accompany the installation. A Fresnel Collector System is a linear concentrating solar thermal collector optimized for industrial use. The system has a thermal peak power of 272 kW and an absorption chiller with a capacity of 350 kW. The cold is directly delivered into the local cooling network, hereby reducing fossil fuel consumption and CO2 emissions.
