ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • 47 www.rittal.co.uk www.rittal.ie Rittal reduction is the technology used, combining a heat pipe with inverter-controlled components. The heat pipe works without a compressor, expansion valve, or other regulating elements and so does not need any electrical energy except to operate the fan. Depending on the thermal energy generated in the enclosure and the current ambient temperature, cooling can be performed with the heat pipe alone. The additional compressor cooling only operates if a large amount of heat has to be dissipated from the enclosure or if the ambient temperature is very high. And what’s more – when it does operate, it is far more energyef cient than conventional units. This is because the compressor and fans possess an inverter-controlled drive, which automatically adjusts their speeds depending on the requirements. As a result, the temperature within the enclosure remains constant, and the energy ef ciency is signi cantly higher than with other more conventional cooling units. Staying cool all the time Alongside energy ef ciency, another feature also reduces the carbon footprint: The new Blue e+ S series uses a refrigerant with a GWP (Global Warming Potential) that is 56 percent lower than those used in comparable cooling units. Furthermore, instead of the R-134a previously used, the cooling circuit in the new generation of units now runs with R-513A refrigerant. Smart communicationenabled capabilities With their additional smart functions, the new cooling units also help in the digitisation process. With a fully integrated IoT interface as standard, the cooling units can be intelligently monitored in digitalised environments and easily connected to Rittal's new Smart Service Portal. This optimises the service processes and increases ef ciency through predictive maintenance. As a result, fewer unplanned downtimes occur which all helps to manage the high cost of production, especially with Industry 4.0 processes. Production-friendly facelift These cooling units in the lower output classes have also undergone a facelift. Their most striking feature is an integrated coloured LED light strip. This means that warning messages can be immediately seen, even from far away. A display on the front of the enclosure provides additional up-to-date information. Moreover, the cooling units are equipped with the familiar NFC interface, which enables them to communicate with mobile devices that have the Rittal Scan & Service app installed.
