Global automotive, building efficiency and power solutions company John-son Controls Systems & Service South Africa has been awarded a multimillion-rand contract to install environmentally friendly chiller and refrigerant flow units at Botswana’s Sir Seretse Khama International Airport, in Gaborone.
The contract was awarded following a rigorous tender process which included criteria such as high-efficiency, good performance and environment-friendly equipment, as well as strong after-sales support.
Johnson Controls reports that it was able to meet the project criteria as it has a strong services and support network across Africa and has products that meet the international standards set for environmental-friendly products.
The three YCIV air-cooled variable-speed drives with environment-friendly R134a gas motor speed drives can be aligned with the needs of the airport and can save up to 30% of cooling energy consumption.
“With variable-speed-drive chillers, such as the YCIV, the airport can proactively drive down its cooling consumption,” says Johnson Controls Systems & Services South Africa business area operations manager Jose Fernandez.
Further, Johnson Controls’ YDS variable refrigerant flow (VRF) units use R410A refrigerant and require no internal plant room space. The volume or flow rate of the refrigerant is also accurately matched to the required heating or cooling loads. This allows the airport to save on energy, as well as benefit from more accurate control. Johnson Controls also reports that the units are easy to install.
The YCIV chiller and YDS VRF units will be installed at Sir Seretse Khama Inter-national Airport over the next few months.The a
irport is currently undergoing a $61-million expansion, which will accommodate increased traffic and larger planes. The aim of the project is to provide the airport with increased capacity for the FIFA World Cup, in South Africa.
