We use two SIMATIC rack IL 40 pc computers which work in very dusty enviroment. We need to buy cabinet with some kind protection from dust and providing friendly enviroment for computers. Basically I need to place two rack PCs with their UPS (two standard units 750VA) inside this cabinet. Is there any standard solution? What would be your advice? Thanks

The worst environment (for dust) we had to work in was a sheettrock manufacturing plant. White dust (chalk)covered eveything in the plant, and it was of such fine grade that it managed to pass through even HEPA filters and gaskets in the standard IP67 cabinets we had ordered. Computers and PLC racks were quickly gummed over, contacts we losing their efficiency... We had the cabinets rettrofitted locally with a positive-pressure design: cleancompressed air, entrance pressure regulated to 0.1 inch of water if I remember well (very low, just enough to push out the incoming dust), with a relief valve (in case the regulator failed, you do not want a hermetic over-pressured vessel!).Make sure of the quality of the pressured air (dust, humidity, temperature) so your computers are happy. From the latest news I had from this project, the company has replaced the PCs inside a couple of times, but not because of the dust problem (upgrades, basically) but they are still using our system for the cabinets. Hope this helps, Daniel Chartier

It is actual and will be for some time. I was searching some kind of standard cabinet with filters and fan that will create overpressure to keep dust out. Do you know any standard solutions (catalog examples)? Thanks
