Enclosures, cabinets and racking panels for electronics often require sophisticated cooling and ventilation if the components housed within are to operate at maximum efficiency and rated lifespan.
"Ziehl-ebm Group, world leaders in motorised fan technology with over 50 branches operative in 30 countries, offers air movement solutions for a wide-range of HVAC applications," comments Allen Munro, marketing manager of Ziehl-ebm SA.
"Whether it is a simple extractor fan to assist ventilation in a single cabinet such as a computer or UPS module, or a highly complex heat exchange unit required for an air-cooled or water-cooled system ensuring stress-free, constant temperature conditions and thus ensuring best operating conditions for electronic components, Ziehl-ebm has international experience with research and development conducted in varying local conditions worldwide," Allen adds.
"Typically, sophisticated systems may feature designs capable of drawing interior cabinet air into a heat exchanger module and utilising a counter-flow principle whereby the exterior air is exchanged and flows through the cabinet and back through the heat exchanger without any direct contact between these movements of air.
"Ambient and site conditions such as dirt, dust or humidity, etc, must also be managed and in such instances our R&D specialists work closely with the engineers designing these systems.
"We in South Africa are able to draw on this expertise and experience and can feed solutions back to local engineers looking to enhance air movement in applications attracting this attention," he concludes.
