Integrated DRUPS systems for uninterrupted critical power

 

For data centers, healthcare facilities, and other critical operations, even short power interruptions can have serious consequences.

Elektromatik delivers fully integrated DRUPS systems designed, integrated, commissioned, and supported to maintain continuous power when the grid supply fails.

A DRUPS solution can help you achieve:

  • Zero transfer time between grid and backup power
  • Reduced footprint compared to traditional UPS and generator setups
  • High tolerance for transient loads and dynamic demand
  • Full lifecycle responsibility from engineering to 24/7 service

Secure operations 24/7 with DRUPS solution

When power fails, operations must continue

Grid instability is increasing, while power density and compliance requirements continue to rise across critical sectors. In data centers, healthcare facilities and other critical environments, even milliseconds of interruption can result in:

  • Data loss
  • System shutdown
  • Operational disruption
  • Regulatory consequences
  • Financial loss

DRUPS helps maintain continuous power without transfer delay and with lower system complexity.

What Is a DRUPS System?

DRUPS stands for Diesel Rotary Uninterruptible Power Supply.

It combines a diesel generator and a rotary UPS into one integrated unit. Unlike traditional setups where a static UPS and a generator operate as separate systems, DRUPS ensures continuous mechanical energy transfer without interruption.

How a DRUPS system works:

  1. The rotary unit provides continuous power conditioning.
  2. Kinetic energy storage bridges any grid disturbance.
  3. The diesel engine starts automatically during grid failure.
  4. The system continues supplying uninterrupted power without switching delays.

Why rotary instead of static UPS?

  • No battery dependency as primary backup
  • Higher tolerance for sudden load changes
  • Lower complexity
  • Reduced system interfaces
  • Simplified maintenance structure

For high-load, high-density environments such as AI-enabled data centers, this stability is critical.

DRUPS vs separate UPS and generator systems

Traditional critical power architectures often rely on separate UPS, battery, and generator systems.

Separate UPS + generator setup DRUPS
Separate systems Integrated solution
Larger footprint More compact design
Battery-based bridging Kinetic energy bridging
More interfaces to manage Fewer system interfaces
Multiple vendors and service points One integrated solution partner
The result is a more integrated critical power setup with fewer interfaces to manage.

FAQ

What is the difference between DRUPS and UPS? A traditional static UPS is typically battery-based and requires a separate generator.
Is DRUPS suitable for data centers? Yes. DRUPS is particularly well suited for data centers with high transient loads and strict uptime requirements.
How does DRUPS handle sudden load changes? Rotary technology allows DRUPS systems to absorb large load variations without voltage instability.
How long can a DRUPS system operate without grid power? As long as fuel supply is maintained, the diesel generator can sustain operation independently of the grid.
What maintenance is required?

Preventive maintenance programs are recommended to ensure continuous readiness. Elektromatik provides lifecycle service and 24/7 support.
Is DRUPS compliant with Nordic regulations? Systems are engineered to meet applicable national and sector-specific compliance requirements.
