Transnet Engineering has placed an order with Booyco Engineering for the supply of 110V DC ventilation units for Traction 1&2 and 3&4 motors. The ventilation units provide airflow to the Traction 1&2 and 3&4 motors deployed in the 10M commuter coaches for cooling purposes and Booyco Engineering has designed them in collaboration with Transnet Engineering. Helen Terblanche, customer service manager at Booyco Engineering, says units supplied through previous contracts have been operating in the field for a number of years with no traction motor cooling problems, and attributes this reliability both to the 110 V DC power supply and the use of EC controlled fans, which are very dependable. The units are based on the latest EC fan technology that is compliant with international railway standards. Fan speeds can be programmed to the requirements of the customer and the system does full fault logging and can provide the train management system with information on the condition of the system.

“The order, which once again showcases our airflow and cooling system design capabilities, was challenging because we were working to meet shortened delivery deadlines,” says Terblanche. “We had to bring quite a few of the orders forward in order to assist Transnet Engineering with successful sales to their customer.” Booyco Engineering’s Quality Management System conforms to ISO 9001. The accreditation agency is BVQi and the company carries UKAS (United Kingdom Accreditation Service) and ANAB (ANSI-ASQ National Accreditation Board) certification. The company’s procedures are audited from time to time by companies such as Denel, GE and Transnet. All large contracts are controlled by a Quality Plan.
