Secure your power supply with NO-BREAK KS®

NO-BREAK KS®7e

 


2750kVA (50Hz) / 3000kVA (60Hz)

New! NO-BREAK KS7e

Meet the latest development from EURO-DIESEL, the next generation of Diesel Rotary Uninterruptible Power Supply systems : the NO-BREAK KS®7e.

Engineered to give the best PUE, power density and the smallest footprint, the NO-BREAK KS®7e delivers up to 2750 kVA (50Hz) or 3000 kVA (60Hz) per unit. This is an ideal solution for data centres who have more and more tendency to deploy UPS systems that save energy and can fit easily into space-constrained buildings.

When the load is separated into critical and non-critical (essential) loads, the NO-BREAK KS®7e-SB (dual output version) delivers up to 3300 kVA (60 Hz) per unit.

Scalable and modular, the NO-BREAK KS®7e is available in building blocks of N, N+N, N+1, 2N, 2N+1 and in Isolated Parallel configuration either at low or medium voltage.

 

NO-BREAK KS7e

 

1

Smallest Footprint

The EURO-DIESEL KS7e is the smallest footprint DRUPS in the world today, which helps to reduce floor building cost and lower CAPEX and OPEX.

2

Auto Greasing

Continuous automatic greasing to all bearings without requiring downtime.

3

Variable cooling

Reduces ventilation losses in accordance to the system load and ambient conditions. This improved design reduces system losses by over 15%.

4

Seismically approved dampers

These dampers are finely tuned to eliminate eventual vibrations transmitted from the Stato-Alternator to the main baseframe and allow direct installation on the floor. They are designed to withstand a seismic rating of 1.39 G, in compliance with the International Building Code.

5

Split frame

Allows easier transport and lifting of the power module. As an option, a daily fuel oil tank is integrated in the base frame to reduce the footprint of the system and simplify the installation.

6

Kinetic energy accumulator

Stores kinetic energy to guarantee a safe transfer from conditioning mode into independent mode at all times. This small section of the power module replaces the use of large battery banks that need extra floor space and special storage requirements.

7

4-Pole Synchronous Machine

Available for MV and LV operations, the alternator generates a perfect sine wave and, together with the choke, performs voltage regulation and removes down- and upstream disturbances.

8

Guaranteed start utilizing an electromagnetic clutch

Maintenance-free electromagnetic clutch ensures a soft and reliable power transmission and acts as a fully redundant start system of the diesel engine.

9

Emissions compliant diesel engine

Digitally controlled, pre-heated and pre-lubricated diesel engine that meets TA-Luft and EPA exhaust emission standards. It guarantees a quick but soft start when needed, ensuring load availability.

10

Monobloc design

Easy and reliable on-site installation: all sections are directly coupled and automatically aligned.

NO-BREAK KS®7e Advantages

                         

 

Even Higher Efficiency

The design of the NO-BREAK KS®7e enables over 20% of power losses reduction which 
makes EURO-DIESEL's NO-BREAK KS® product range the most efficient Diesel Rotary UPS systems in the market.

 
 

ECO-MODE

As every kW counts, the NO-BREAK KS®7e has been programmed to include Eco-Mode function -- the speed of the accumulator adapts automatically to partial loads, reducing the energy losses even further.

Efficiency
 

100% Uptime

With the NO-BREAK KS®7e, you are able to perform maintenance program while the UPS system stays fully operational. In other words, your load is secured at all times and any maintenance works will not interfere with your daily operations of your facility.
