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 Uptime Institute has developed a Tier classification based upon four standards; Tier I to Tier IV.
The purpose of this standard is to equip the industry professionals with an objective way to evaluate the performance of a data centre or the quality of its design.
E1 DYNAMICS designs its systems according to the Tier classification criteria for data centre applications and has since implemented Tier I to a Tier IV (2N) configuration.
A Tier I is a basic design and can be a single system or multiple NO-BREAK KS® systems operating in a non-redundant capacity.
A Tier II NO-BREAK KS® design means that the power supply is guaranteed at N+1. For example, at LV or MV parallel configuration, all units supply to the load by means of one common output bus.
Concurrently Maintainable Infrastructure
A concurrently maintainable NO-BREAK KS® system means a redundant capacity (N+1) in combination with multiple independent power distribution paths, serving the computer equipments. Only one path needs to be active at any time. This means that each and every component in the NO-BREAK KS® system can be maintained at a regular basis without impacting the load.
During maintenance, the risk of a disruption may increase. An unplanned outage during these activities may gravely impact the load.
The utility power supply is considered the alternative power supply for Tier III applications and the NO-BREAK KS® is considered the main power source. As such, diesel engines cannot have any runtime limitations at N demand to meet Tier III, which means that the engine needs to be rated at "continuous power" and not at "standby power" or "prime power" rating. To meet Tier III, the NO-BREAK KS® units are configurated as a distributed redundant configuration or as an LV/ MV parallel configuration with a dual path downstream distribution system.
Fault Tolerant Site Infrastructure
A fault tolerant power supply has multiple physically isolated NO-BREAK KS® systems that provide both redundant (N+1) by separating active independent distribution paths which simultaneously power to the data centre load.
All single point failures are eliminated. A single failure of any component or at any point of the distribution will not impact the data centre load. Each and every component can be removed and maintained on a planned basis without impacting the data centre load.
In line with Tier III the diesel engine needs to be designed at its continuous power rating so that it has NO operating limitations while running at N for weeks or months.
The NO-BREAK KS® configuration consists of an independent A side (N+1) and an independent B side (N+1) powering the load by a dual distribution system. The A and B sides normally consist of multiple medium voltage NO-BREAK KS® systems.
