  • 2016.06.20 EURO-DIESEL in the News - Jobs Regions 17062016


    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.

  • 2016.03.10 Middle East Electricity exhibition 2016


    In early March, our Middle Eastern team participated in the Middle East Electricity exhibition which was held in Dubai.  It was a great opportunity to present the many projects we have carried out in the region covering datacentres, airports and municipality applications and to share the impressive references EURO-DIESEL has received for these projects. [+]

More than a UPS : Two functions in one

Many industries have a combination of critical (UPS) and non-critical (SB) loads in their facility. The NO-BREAK KS®-SB is the perfect match to combine both load types by powering the critical loads at all times, and then powering the non-critical loads within a maximum of 10 seconds break.

The NO-BREAK KS®-SB eliminates the need of additional diesel generators, saves on floor space and eventually, saves on building costs. As a result, this reduces the total Cost of Ownership.



NO-BREAK KS5-SB Conditioning Mode




NO-BREAK KS5-SB1 Conditioning Mode


The critical loads (UPS) are fed via the conditioned power of the DRUPS: Q2 is  closed.

Non-critical (SB) loads are fed direct from the utility: Q5 is closed and Q6 is open.  When a utility interuption occurs the breaker Q5 opens and within a maximum of 10 seconds, Q6 is closed to provide power to the non-critical loads via the diesel engine.

On mains failure, the critical loads are automatically protected at all times.



Single lines SB2

The introduction of a tapped choke in the electrical scheme provides an additional advantage: in case of a short-circuit on the non-critical busbar, the critical load will be unaffected since the choke will reduce the influence on the critical busbar.


Note :  It is recommended that for all NO-BREAK E1-SB systems, the critical loads be larger than the non-critical loads.

Output power split example (in 60Hz):   

1.   UPS Critical load = 1500kW, total output power = 2000kW. Therefore the rating is 1500/2000kW.



Technical and economical advantages:

  • Critical and non-critical loads are supplied from one system, therefore no need to install a separate generating set for the non-critical loads
  • Compact solution with small footprint: only one room required for installation
  • Lower installation costs due to reduction in cabling and switchgear requirements
  • Possibility to parallel  systems


Note: The above systems are also available in medium voltage.
