Hyperscale cooling in compact design
STULZ HAS ANNOUNCED the availability of its CyberWall cooling solution.
Designed for operators of large, colocation and hyperscale data centres, it comprises a range of precision air conditioning units specifically de- veloped for facilities with separate aisles.
Its horizontal airflow technology enables reli- able operation of high IT load densities without the use of raised floors or side coolers.
Heat density within racks is increasing with each new generation of data centre equipment.
In order to protect equipment and offer unri- valled levels of cooling performance, CyberWall is configured around high performance fan walls comprising cutting edge electronically commutated (EC) fans with integrated air/wa- ter heat exchangers.
This allows a cooling capacity of around 100kW per metre of wall length to be achieved and means that the efficient air conditioning of high power densities, as well as racks of 42U or more, is now possible.
With data centre white space now at a pre- mium, STULZ has designed CyberWall so that indoor air handlers with cold water con- nection can be mounted in rows or stacked
without gaps, making use of all availa- ble wall space and optimising system performance.
Mounted at the aisle end, where they supply individual rack rows horizontally with cold air, the warm aisle is separated by a containment system with a ceiling duct, so that reliable separation of cold and warm air is guaranteed.
The CyberWall system also fits precise- ly into the existing service corridor, which allows the maintenance of air condition- ers to be completed without the need for personnel to enter the server area.
STULZ CyberWall modules achieve an impressive cooling capacity of 220kW, with 16°C water inlet, and an airflow rate of 55,000m3/h per air con- ditioning unit.
As part of its pioneering Custom In-
door Air Handling Unit (AHU) series, STULZ provides a wide range of output sizes and special designs, offering customers a com- prehensive portfolio of unit dimensions, com- ponents and capacities to meet specific re- quirements. Visit:: www.stulzoceania.com

its panels still perform to the same levels at the end of their life as they did the day they were installed.
R values: the new NCC requires manufactur- ers to calculate R values for summer conditions and winter conditions, and the requirements vary according to Australia’s eight different cli- mate zones. Six of these climate zones require R valuestobecalculatedforsummerconditions, while the remaining two require R values to be calculated for winter conditions due to the ex- tremes in temperature in these different zones. Kingspan panel systems are all fully compliant with the R values required by the new NCC.
Thermal bridging: Built-up systems have ex- ternal layers that are attached through fixings, creating a thermal bridge and letting heat out, which reduces energy efficiency. Because King- span Insulated Panels systems are all-in-one, there is no thermal bridging. This means King- span offers the best and simplest solution to meet R value requirements in the new NCC.
This is in addition to full compliance with AS/ NZS 4859.1 and AS/NZS 4859.2.

NCC ready insulation
INSULATED PANELS MANUFACTURER,
Kingspan Insulated Panels, has advised archi- tects and specifiers that it is fully compliant with the new National Construction Code (NCC), which recently came into effect.
Complying with the new performance require- ments can help reduce greenhouse gas emissions
in Australia, so architects and specifiers need to be confident that their choice of materials and systems can deliver the best performance ac- cording to the revised NCC.
Using Kingspan Insulated Panels im- proves the efficiency of buildings over and above the standard.
Kingspan Insulat- ed Panels systems fully comply with key aspects of the NCC including:
Aged lambda: this measures the ther- mal performance de- livered by a product at the end of its life. Kingspan Insulated Panels offers a 25- year warranty and
Kingspan Insulated Panels systems comply with the new construction code.
