Rittal have introduced a range of cooling units specifically designed for outdoor enclosure applications. If you want your (electronic) kit to remain useful for longer when situated out of doors, then give it some air!
Any outdoor enclosure will suffer from Solar Gain on long and hot summer days and as a result the internal temperature will rise above the ambient. It is well known that the life expectancy of most electronics will fall dramatically with a temperature increase above 30-35° Celsius. Electronics sealed in an outdoor enclosure will effectively cook unless there are some simple measures taken to both remove any generated heat, and reduce or eliminate the effect of the sun.
Rittal include several standard outdoor enclosures with twin walls, separated by a 25mm air gap, which provides a suitable home for sensitive equipment, all featured in their CS Outdoor enclosure selector. In addition, they are able to supply either built into the enclosure, or as separate “after-market” items, a range of air conditioning units which maintain the IP55 rating of the enclosure.
Designs specifically for use in roof mounting, side wall, rear panel or door mounting applications are available, with cooling capacities ranging between 750W and 1750W and providing from 570m3/hour of cooling air through to over 1000m3/hour to cater for a wide range of circumstances.
