First, ask yourself some simple questions: • Is your equipment tripping or failing due to high temperatures? • Is this having an impact on production, in that it’s either slowing or stopping completely? • When you walk around your shop oor, do your enclosures feel hot to the touch? • At the height of summer, are your enclosure doors regularly left open and do you need large fans blowing into your panels to cool the devices inside them? • Does inadequate chilling of process uids result in production downtime? • Would your existing cooling solution bene t from a health check? Our engineers will always offer their advice from the perspective of functionality, energy ef ciency, ease of installation, service and maintenance, based on real life data measured on site. Protecting Control and Automation Equipment Your decision as to which cooling solution you choose ultimately depends on the amount of heat produced inside the panel and the environment in which it’s installed. Your choice, in other words, must be speci c to your particular application. The main consideration is whether the panel is located in a cold or hot environment and if that environment is clean or dirty. It would be nice, actually, if the answers were as black and white as these questions suggest! They typically fall somewhere in between. Conditions may also change over the course of the working day, week, month or year, so the nal selection of an appropriate cooling solution may not be entirely straightforward. Enclosures which are located in a cool and clean environment may nd fanand- lter units are adequate, given a single device provides more than 4 kW of cooling in ideal conditions. If the air is dirty, it is still possible to take full advantage of low ambient temperatures by using energy ef cient air-to-air heat exchangers to provide any necessary cooling. For applications that require the temperature inside the enclosure to be lower than that outside it, a refrigerant based solution may be the best option. The new Blue e+ cooling unit range from Rittal, with capacities up to 6 kW, can operate in ambient temperatures up to 60 degrees Celsius yet also provide free cooling when the external air is cooler due to the innovative use of hybrid technology. Air-to-water heat exchangers may be used in even hotter conditions and the water delivered to a remote location in which the heat, up to 10 kW from one unit, may be dissipated more effectively and with less effect on the temperature of the surroundings. So, with all this sorted, you just need to check your passport is still in-date…. For more information and advice on cooling: contact +353 599 182100 or email sales@rittal.ie.
