A novel solution to common cabinet ventilation problems
09 December 2010
Ventilating electrical enclosures can be a problem, especially when an efficient airflow is to be combined with a high IP rating (IP54 or IP55). Several methods are available, such as using door mounted filtered fans designed to provide cooling air that is free of both dust and moisture. Occasionally, there is little room in the control panel for the fan at the back of the filter. Roof mounted extraction units using backward curved centrifugal fans can be used, but these are limited to IP24.
Thermal management solutions manufacturer Fandis has found the solution to this problem by adding G2 filter media inside its 'TP' series roof ventilation units, to achieve IP54 protection. A gasket is also provided to optimise the cabinet environmental integrity.
