Custom made mobile air-handling systems designer, developer and manufacturer Booyco Engineering is currently working on the manufacturing of heating, ventilating, and air conditioning (HVAC) systems that will be delivered to train manufacturer Bombardier Transportation in 2018.
The HVAC systems will be installed by Bombardier into the 240 Bombardier TRAXX Africa – the Class 23E locomotives it is building for State-owned freight rail company Transnet Freight Rail (TFR) to use in its General Freight Business division.
Booyco Engineering says winning the contract from Bombardier, awarded in November last year, is testimony to its international reputation in engineering and specialisation in HVAC solutions.
The company says the HVAC systems are an evolution of the previous systems, which were engineered for the 15E and 19E locomotives. These systems have an established track record for reliable performance under the harsh operating conditions in South Africa, making them suitable for even the most demanding environments worldwide.
“What is of great significance is that Booyco Engineering is dealing with sophisticated international players whose standards and specifications are at a high level. This contract underlines our ability to perform at this level and firmly positions us to participate in the international market on an ongoing basis,” says Booyco Engineering CEO Jeremy Pougnet.
He adds that Booyco Engineering’s successful track record is underpinned by verifiable data from the in-field operation of the HVAC systems, which shows that mean time between failures is exceeding expectations.
The new HVAC systems also incorporate an integrated fresh air control that allows the fresh air inlet to be temporarily closed when the locomotive travels through areas where the ingress of the outside air is undesirable.
In addition, the maximum ambient temperature specification was raised and the condenser heat rejection capacity was increased accordingly.
The 8.3 kW cooling system is rated for an ambient temperature of 50 °C, with a 4.5 kW heating system. In addition to being designed to achieve low noise levels, the Booyco Engineering units are also robust – affording optimal reliability and availability.
In addition to the HVAC systems for the locomotives, Booyco Engineering also secured an order for 480 cooling towers from Bombardier, which provide cooling for the transformer and converters on the locomotives.
“It is our ability to understand heat transfer, air dynamics, fluid flows, pressure drops and structural design that positioned us to secure this additional order. Added to that, we have a solid understanding of the harsh operating conditions for rolling stock, which include shock and vibration,” Pougnet points out.
He says the order includes two cooling towers per locomotive application and the units have successfully passed all qualifications tests to date, including thermal testing in Europe. Final acceptance will be based on the vehicle test on the locomotive.
“We have leveraged our extensive expertise, experience and capabilities and increased our capacity through upfront resourcing and investment to ensure that we are in a position to deliver products expeditiously. Our responsiveness, competence and technical engineering support have been duly noted by the client,” Pougnet concludes.
