‘Quantum leap’ in enclosure cooling cuts energy use by 75%

20 April, 2015

The new cooling systems will be available in ratings up to 6kW and can be used at temperatures from –30°C to +60°C. They have a patented multi-voltage operating capability, allowing them to run on input voltages from 110V (single phase) to 480V (three-phase), at grid frequencies of 50 or 60Hz. This will allow the same cooling system to be used almost anywhere in the world – an attraction for exporting OEMs which will result in a reduction in the number of device variants, as well as simplifying spare parts logistics.

Rittal's new cooling systems can be parameterised wirelessly using a smartphone

A multilingual TFT display on the front of the cooling system provides relevant information at a glance in plain-text messages. Standardised communication interfaces simplify integration with control systems. Support for protocols such as CANbus or Modbus TCP allows real-time data transfer via a CAN or Ethernet interface. A near-field-communication (NFC) interface allows multiple cooling systems to be parameterised easily using an NFC-enabled mobile device such as a smartphone.

The potential savings in energy use and carbon emissions from the new generation of cooling systems are substantial. Rittal estimates that in Europe alone, there are around two million enclosure climate control systems in use, with a total connected load of around 2TW (assuming an average of 1kW per enclosure). These systems are responsible for about four million tonnes of CO2 emission per year.
