Rittal system climate control offers holistic process protection. This includes the cooling of sensitive electronics in enclosures and cases for industrial process control, as well as server and network technology, regardless of the ambient conditions. But these are not isolated solutions with Rittal, everything is interconnected. Perfectly linked and controlled cooling technology with eco-friendly, energy-efficient equipment.
Recooling systems ensure centralised, efficient cooling and provision of the cooling medium (generally water). For example, all cooling tasks on a system or machine can be solved via a single pipeline system. Spatial separation between cooling production and process cooling can be achieved with re-cooling systems.
The requirement for use of air/air heat exchangers is that the ambient temperature must be below the enclosure internal temperature. Dust and any aggressive ambient air is unable to ingress the enclosure interior, thanks to the two separate air circuits.
The air of the enclosure interior may also be cooled to below the level of the external temperature by using air/water heat exchangers with a central recooling system. Dust is unable to penetrate the enclosure. The waste heat from the enclosure does not raise the temperature of the ambient air, provided the cold-water supply system is spatially separated.
Fan-and-filter units are ideal for dissipating high heat loads cost-effectively. The pre-requisite is that the ambient air must be relatively clean with a temperature below the desired enclosure internal temperature. The entire range of fan-and-filter units is now also available with EMC shielding and all required rated voltages.
Condensation poses a particular risk for control electronics, especially with outdoor siting, but also indoors. Various different output categories ensure that the correct thermal output is always available. In this way, the total required thermal output can be distributed with complete accuracy within an enclosure.
