Retrofitting Air Handling Units

While architects and building engineers have historically focused on thermal comfort and cost reduction when designing and constructing buildings, the SA Department of Labour in March published a new Code of Practice that includes a focus on increased ventilation rates. But simply pumping in air from the outside is not the answer, as SA’s fine particle […]

High-performance Oils for HVAC Applications

A major cause of reduced efficiency in refrigeration equipment arises from using conventional refrigeration oils as opposed to the specialised synthetic lubricants required for heating, ventilation, and air-conditioning (HVAC) applications. “Failure to use the correct refrigeration oils can result in leaks, reduced filter lifespan, and increased energy consumption,” says Gerald Langley, at Fuchs Lubricants South […]
