Johnson Controls is a global diversified technology and industrial leader serving customers in more than 150 countries and their focus is mainly on Africa. Johnson Controls market through many channels; they sell directly and through agents.
Neil Cameron, Area General Manager of Johnsons Controls says, “TheYVAA and YMC2 have built-in variable speed drives (VSD’s) which makes them well suited to operate on generators. The YVAA and YLAA units are air cooled which makes them simple to install and operate without the need for additional water and water treatment.” Johnsons recently supplied chillers to Aga Khan Hospital in Nairobi, Christ Embassy in Nigeria, Proctor and Gamble in Lagos and Buly mine in Tanzania. Neil advised that people should look for reputable suppliers that back up the sale support and spares availability.
