Is it a generator? A UPS? A flywheel? The new backup power systems at colocation specialist FORTRUST bring these elements together. As FORTRUST expands its Denver data center, it will use Diesel Rotary Uninterruptible Power Supply (DRUPS) from E1 Dynamics to provide emergency power during utility outages. The DRUPS unit features a diesel engine and a rotary UPS that uses kinetic energy, eliminating the need for batteries.
Bien que ne faisant pas directement partie de l’aéronautique à proprement parler, la société EURO-DIESEL entretient néanmoins des liens étroits avec le secteur. Le plus évident est probablement le rôle essentiel joué par son produit phare auprès d’un de ses clients les plus importants: les aéroports & tours de contrôle du trafic aérien. Le très haut degré de technicité de ce produit le rend également comparable aux technologies de l’aéronautique. Nous avons rencontré Philippe Gillain, administrateur délégué d’EURO-DIESEL, qui nous explique les spécificités de cette entreprise liégeoise, et les profils qui contribuent à sa réussite.
EURO-DIESEL (UK) Ltd exhibited at Data Centre World 2016 at the London Excel on the 12-13 April. A major event in the Data Centre calendar - this year’s show was bigger and better than ever with over 250 exhibiting companies. With strong footfall to the EURO-DIESEL stand, the team were kept busy meeting new and existing contacts from across the industry.[+]
The first of eight 2500 kVA NO-BREAK KS®7e units’ arrived to its final destination in Singapore.
The manufacturing process of mixed signal (digital and analogue) chips for microelectronics is an extremely sophisticated process demanding a very strict manufacturing environment.
These chips are used for telephone switchboards, GSM chipsets, ADSL modems, in Bluetooth technology and in the area of automation for access control, sensors, airbags, and in Xe light control. Other applications are for computer peripheral hardware such as control motors for printers, scanners and battery management systems.
A Belgium based manufacturer of such chips found it necessary to undertake detailed research of its site before placing the first stone on a new factory's foundation. Part of the study involved checking the power supply quality and site vibrations. Any loss of electrical power or disturbance in the building could seriously damage the production process. in addition, any impact on production would result in serious financial losses.
The site analysis included monitoring the quality of the power supply delivered by the utility. It was found that disruptions (voltage dips, spikes, and transient interference) occurred approximately eight times per year and lasted less than one second. In addition to this, complete power failure occurred approximately once per year. The consequences of these incidents could then be associated to financial losses by calculating the amount of scrap product, the costs to clean and re-instate production lines and the personnel shift time lost.
It was found very profitable to invest on an Uninterruptible Power Supply and to install it on the new site. The DRUPS would clean up the mains power and guarantee production continuity with no interuption should the mains fail.
EURO-DIESEL was contacted by the customer's engineers to help solve the power problems at the site and also to help meet the stringent environmental constraints, particularly with respect to vibration levels.
The engineers opted to split the site load into critical and non-critical elements to enable the optimum use of the diesel back-up.
EURO-DIESEL proposed a DRUPS system comprising of two EURO-DIESEL NO-BREAK KS®SB machines and housed in containers located outside the factory. The noise level was kept within narrow tolerances to comply with the stringent local regulation and the containers were mounted on heavily reinforced concrete slabs, isolated from the surrounding ground by polystyrene layers.
The NO-BREAK KS®SB system is an original solution enabling both critical and non-critical loads to be supported from one machine in the event of a mains failure.
In normal operation the mains power to the critical load is fed through a choke working in conjunction with a synchronous generator, which filters the mains power and provides voltage stabilisation. Meanwhile, non-critical loads are fed directly from the mains as normal.
When the mains power fails, the back-up diesel engine is started in less than 3 seconds. During this time the critical load is supported by the stored kinetic energy in the uniquely designed EURO-DIESEL accumulator and it suffers no interruption. The non-critical loads will experience a short outage of approximately 12 seconds and are then reconnected to the NO-BREAK KS®SB.
