Mobile network firm MTN has announced that it is the ‘first in Africa’ to set-up a solar cooling system to assist in powering its data centres in Johannesburg, South Africa 

The company, who currently has operations in 22 countries across Africa, Asia and the Middle East, said it is using Linear Fresnel Concentrating Solar power (CSO), which generates heat from the sun and has a peak cooling capacity of 330 kW.

“The system consists of 242 solar mirrors covering a total area of 484 sq m, which track the sun to generate pressurised hot water at 180 degrees Celsius,” stated MTN, speaking about the facility that is located near its head office in Johannesburg, South Africa.

“The hot water in turn powers an absorption chiller that produces chilled water circulated into the data centre for cooling of IT equipment,” added MTN.

The system, which was developed by REACH Renewable and AOS Consulting Engineers and launched jointly with Industrial Solar, Voltas Technologies and Luft Technik, uses mirrors to track sun movements using global positioning satellite technology, MTN said.
