Keeping cool and avoiding business disruption T

he phrase “up-time” is an oft-repeated phrase for IT professionals, reflecting

the fact that a key measure of their success is service availability. Modern climate control systems support “up-time” but to understand why, you first need to consider the impact of poor climate control in order to decide which equipment to employ to take an installation to the next level. Increasing performance capabilities leads

to the heat-load within racks rising. If this is left unchecked, notably after an upgrade, it risks causing significant harm to your IT systems. IT equipment is extremely sensitive and must be kept in a strict temperature range to perform to its full potential. Straying outside these limits will speed up ageing, shorten its lifespan and ultimately increase costs. Equipment exposed to higher

temperatures will reduce output to the point where it may shut down if a high enough threshold is met. Not surprisingly, mission critical equipment that ceases operating can have very serious consequences for a business. Users who have added additional equipment may find their cooling system has to work harder to maintain the status quo, which then leads to a spike in energy

within the space either side of the 19” angles. These points allow both hot and cold air to mix and permits ambient air into the rack. The application of brush strips to the roof and base plate still allows the installation of new cabling, while still ensuring an effective seal. Foam strips that can be modified to suit a gap provide a solid barrier to either side of the angles and prevent an air short-circuit. Aisle containment: If perforated doors

consumption as well as a reduction in the life of the cooling system.

SMALL CHANGES FOR MAJOR IMPROVEMENTS Blanking spare U’s: Unoccupied rack space can mean the resulting spare ‘U’ is left vacant. This allows hot air to leak into the cold area of the rack, which in turn affects the overall efficiency of the cooling equipment, reducing the ‘ΔT’ along with the overall cooling performance. The use of blanking strips can fill up the spare ‘U’ and ensure separation. Brush/foam strips: The same principle applies anywhere cables enter the rack and

are being used then the installation of aisle containment should be high on the priority list. This is a system of door and wall pieces which create a barrier between the warm air and the cool air. The layout is at the customer’s discretion but a ‘Cold Aisle’ creates a pocket of cold air which can be utilised by all racks in the vicinity, and the ‘Hot Aisle’ is the opposite, in which the hot air from numerous racks is kept in one zone. This system is practical, it is modular and

suits existing installs. It can increase performance and reduce the energy consumption of existing cooling equipment which may avoid the need for an upgrade.



s part of its innovative energy distribution capabilities for buildings,

ABB introduces its System pro E energy range of sub distribution boards, that provide greater reliability, flexibility and significantly reduce assembly time. The System pro E energy range

provides commercial and industrial end- users with easy to install, flexible and safe applications that can integrate all types electrical devices to build distribution panels up to 800A. It is the first ABB solution that combines ABB technology and the former GE Quixtra platform to provide a ‘best of both’ technology solution. Installing the System pro E energy

range can have a significant positive impact on overall efficiency for the end- user, with ABB estimating it can save up to 80 per cent in assembly time. It also requires 30 per cent less stock, 15 per cent fewer order codes and improves wiring space capacity by 20 per cent. This increase in operational efficiency can also help optimise energy distribution– a key feature of ABB’s smart energy management technologies. The System pro E range consists of


with a modular system that includes all the individual parts required for assembly. This allows the end-user to take a flexible approach towards stock keeping and avoid a time-consuming search for system parts, such as brackets, screws or fasteners. Piero-Giorgio Schiannini, global

wall-mounted and floor-standing sheet steel cabinets, as well as busbars and functional units, and allows maximum flexibility for the panel builder and installer to build distribution boards for any application. The range is also extremely safe - the

System pro E energy L provides a protection degree up to IP43 and the System pro E energy M, the mono-block solution - up to IP55. When combined with ABB’s DIN-Rail devices the range is also certified to IEC 61439 standard. In addition, System pro E energy

Combi facilitates internal configuration

Operational efficiency can also help optimise energy distribution

product group manager energy distribution, comments: “ABB is always striving to develop solutions that allow customers to save time and money, through a combination clever design and smart technology. Our new System pro E energy range of sub distribution boards combine with connectivity devices to provide effective digital energy management solutions for commercial and industrial applications. The technology is flexible, easy to assemble and meets the highest safety standards. This means that installers and end-users can be confident that they are using the most safe, reliable and efficient solution for their energy distribution.”
