Rittal and the IEC 61439 Standard

Design engineers should be aware that the the IEC 61439 switchgear and controlgear systems standard will take effect from November 2014. This standard also applies to wall mounted control panels as well as floor standing power distribution assemblies.

For the smaller control panels with current ratings of below 630A, the ratings of the busbar system and controlgear components must be de-rated in line with the standard. A key feature of the standard is the calculation of the maximum internal temperature of enclosure.
To assist the design engineer Rittal can supply Therm software that will calculate internal temperature and Power Engineering software that can design the panel layout in line with the standards.

For further information regarding Rittal solutions and assistance with compliance to IEC 61439, please contact Mark Guest mguest@rittal.co.uk or, to receive a free copy of the guide book, please use powerdistribution@rittal.co.uk

iomart Wins Data Centre Excellence Award from Rittal

Cold Aisle Containment Technology Optimises Power Efficiency in iomart DCs

iomart (AIM:IOM), one of the UK and Europe’s leading cloud companies, has been recognised by global systems provider Rittal for its innovative approach to data centre technology.
iomart uses Rittal TS IT enclosure systems in its data centres to provide the optimum environment to host the servers and network requirements of its customers. iomart was the first data centre operator to use Rittal’s I/0 Cold Isle Containment System which provided a 50 per cent increase in cooling efficiency from the day it was installed.

Shane Hope, IT Sales Director for Rittal, said: “This award recognises iomart’s superb technical approach to efficiency and control within its data centres. We have a great long-term relationship with iomart and continue to provide it with the innovative products that help it provide mission-critical infrastructure for businesses and organisations throughout UK and Europe.”

iomart is about to complete work on increasing the capacity of its data centre in Maidenhead by a further 600+ racks to meet greater demand for data storage. It is utilising Rittal Cold Aisle Containment to accommodate high density power draw within the new racks.

Neil Johnston, Group Technical Operations Director for iomart, said: “Rittal provides us with consistently innovative technology. For our most recent expansion in Maidenhead they’ve provided us with the most energy efficient systems to optimise our new cooling technology.”

Rittal’s Support Arm System now with automatic potential equalisation

Rittal is the first manufacturer to ensure automatic potential equalisation as a standard with its new CP 60/120/180 support arm system, without any extra work and additional costs to users.

Where previously the focus has been on the mechanical structure of support arm systems, cable installations within support arm systems often had no passive internal safety devices, such as edge protection elements, to prevent chafed cables. Active protective measures were also absent, such as automatic potential equalisation throughout all the elements of a support arm system to protect the operator from live electrical voltage in the event of a defective cable.
With Rittal’s new CP 60/120/180 support arm system all the rotating elements have so-called sliding contacts to ensure a reliable electrical contact throughout the entire system. Clever edge protection elements made of plastic, which can simply be clipped onto the inner section between extrusions and corner pieces prevent cables from becoming pinched or chafed.

As an integrated modular system, Rittal’s CP 60/120/180 support arm system offers plant constructors uniform function, assembly and engineering solutions in one design, and meets all the load ranges up to 180 kg demanded by the market. It also offers major time savings during assembly, adjustment, and service.

Rittal Housings for TFT monitors

Rittal’s stylish housings, with a protection category of IP 65 shielding devices from exposure to dust and water jets, are designed to accommodate TFT screens up to 24” (measured along the diagonal) in the popular 16:9 and 16:10 widescreen formats.

A full-width viewing window made from a single-pane of safety glass maximises the display area and a combination of rounded edges and aluminium grips prevent injury. The side facing the operator has an attractive look and feel.

Housings containing TFT screens can be mounted quickly and efficiently thanks to a holder with the VESA 75/100 mounting hole pattern. A hinged door on the back of the housing provides easy access to the device. Manufactured from sheet steel, Rittal’s housing measures 650 x 450 x155 mm.

To provide additional ways of connecting to a machine according to the needs of the application, the housing can easily be mounted to a support arm system from Rittal’s CP 60/120/180 range.

With eccentrically mounted support arms, the housing can be placed in various positions, such as in niches. For the fitter’s convenience, pre-punched holes are provided in the reinforcing plate.

Save Energy by Cooling with Water

 

Rittal air/water heat exchangers are capable of cooling the air in an enclosure to a temperature lower than that of the ambient air. Heat to be removed is transferred to a water circuit and may be conveyed to a remote location before being dissipated. The lack of dependence on ambient air results in a maximum operating ambient air temperature of 70 °C.  Air is recirculated inside the enclosure maintaining an ingress protection category of IP 55.

Cooling with water may also be considered from an energy saving perspective. Air/water heat exchangers supplied with the eComfort controller incorporate the Eco-Mode control functionality. This employs an intelligent strategy to effectively target the use of energy by disabling the internal fan when the temperature inside the enclosure falls to a predetermined level below the setpoint. The fan is then pulsed periodically to ensure the accuracy of the sensed temperature before being permanently enabled when the temperature rises above the predetermined level.

Although the capital cost of a cooling system incorporating multiple air-to-water heat exchangers and a single water chiller may be greater than that of an equivalent number of refrigerant based cooling units, energy savings are typically in the region of 40 per cent.  Efficiency of water cooling systems may be further improved, particularly in the climate of the United Kingdom, by locating water chillers externally and integrating dry air coolers to take advantage of free cooling.
