With the price of standard computers dropping, this puts computers in the reach of everyone, most homes have at least 1 computer and 1 laptop, with the low cost and availability businesses are now using them to monitor and control the production on factory floors.
However we all know that the standard computer is best suited in an air conditioned office, so as soon as they are introduced to factory floors that are dusty, dirty and full of grease, problems occur, with lost data and this can result in lost production time.
To combat this, some companies either build custom offices on the factory floor at a cost of thousands to have an area that is safe and free from relevant dust contamination or they purchase special industrial computer cabients that offer a safe protective environment for the computer to run without being effected by any dust, grime or fluid that is in the surrounding area. The computer enclosure is a more affordable solution, as it can be relocated if the production line is increased or reduced, were as the office would have to be demolished and rebuilt!
Industrial computer cabinets are cooled depending upon the application and the extreme temperatures, there are solutions to cool an enclosure to -30 degrees and there are solutions to heat the enclosure to +60 degrees Celsius. Air cooling units are also available, however they have moving parts than do wear out over time, there are options to maintain a ambient temperature inside the cabinet even if the external temperature range is to variable.
One solution to use in large temperature ranges, is a cooling tube, these run on compressed air and once fitted to the industrial computer cabinet, are set to the desired internal temperature, for example 20 degree Celsius and it does not effect the hardware if the external temperature drops to -20 degrees or 140 degrees Celsius, as the internal temperature is a steady 20 degree C. These cooling tubes have no moving parts, so there is nothing to wear out and they will certainly pay for themselves.
This is why many general manufacturers such as Ford Motors, Vauxhall, Paccar Trucks, and SCA Hygiene use computer enclosures, to protect their computer hardware and to help control production.
