Cooling advice

“Don’t be lulled into a false sense of security because the temperatures are dropping,” advises Christian Westwood Rittal’s product manager for climate offers advice on designing effective climate control systems. “Instead why not use this time to consider your best options?

“Rittal’s expert team can provide you with free advice as to which cooling product is suited to your particular application, or arrange a survey, so we can propose the best solution.

“We always consider options with users from the perspective of functionality, energy efficiency, ease of installation, service and maintenance, based on real life data measured on site."

Enclosures which are located in a cool and clean environment, may find fan-and-filter units are adequate, given a single device provides more than 4kW 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 efficient 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˚C 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.
