Weidmüller filter fans - Optimised energy consumption thanks to enlarged air flow and reduced current consumption
Service life of the innovative folded IP55 filter mat up to three times longer / 4-corner snap-fit mechanism for rapid and tool-free installation / Easy-to-use hinged cover for quick and simple filter mat changing
(PresseBox) - More and more active electronics, ever more compact design types, ever more wiring thanks to space-saving connection system: the space in the control cabinet has never been better utilised. But this also causes an increase in waste heat that should be dissipated. Weidm the control cabinet, and finally it exits through an output filter. Filter fans are deployed in the case of power losses in the control cabinet of typically between several hundred watts and several kilowatts. As long as the temperature and the quality of the ambient air, and the waste heat that is to be dissipated allow, the fans are an extremely economical alternative to cooling units, both in terms of procurement and in operation. Cooling significantly extends the life expectancy of electronic components.
Weidmable with grey and black enclosures. A 4-corner snap-fit mechanism enables rapid and tool-free installation. All design types are available in different sizes and with different power levels. The smallest device has a volumetric flow of 25 m3/h, an edge length of just 109 mm and a depth of 62 mm. The most powerful device offers a volumetric flow of 925 m3/h. It has an edge length of 320 mm and a depth of 157 mm. With the design of all the filter fans, attention was paid to energy-efficiency and a long working life. If one fan should fail, it can very easily be swapped out separately. This is possible thanks to the cable gland installation and the use of a terminal block for the electrical connection.
Weidme working life of the folded filter mat used in the IP55 version is extended by up to 300%, in comparison to traditional filter mats. The filter mats can be swapped out quickly and simply through an easy-to-use hinged cover.
A range of matched accessories complements the programme of fans. There is, for example, a selection of heating and control elements that reliably prevent the build-up of condensation in the control cabinet. The heating elements are designed for a 100V to 250V power supply and as an option, are available with a thermostat. The programme also includes separate thermostats, with a switching range from -20ted by a hygrostat with an adjustable tripping value of from 40% to 90% relative humidity. In this way, filter fans and heating elements only work when cooling or heating is actually required. Energy-efficiency can be increased and costs can be decreased by the needs-based usage of thermostats and hygrostats.
Now, there is nothing standing in the way of achieving perfect climatic conditions in the control cabinet.
