Towards safe data centers with net zero emissions and 99.99% uptime
IT cooling consumes significant energy in heat management of servers, while generating a great deal of excess heat. This makes reduction of the climatic impact of digitalization a high priority since data center growth is expected to accelerate.
To achieve net zero emissions, a smart combination of technologies is required, keeping circular economy, safety, and demand-side flexibility in mind.
Danfoss solutions help the full range of data centers reach high power usage effectiveness (PUE) and energy reuse factor, while supporting reliably high uptime.
Data centers must operate continuously even in a fire situation. Danfoss offerings include solutions for cooling, fire safety, power distribution, energy storage, and heat recovery.
“Strong efforts on energy efficiency and initiatives on demand response and waste heat utilization can help minimize the impacts of large data centers on the grid as well as the environment. Ensuring that data centers are powered with zero-carbon energy sources can help to reduce these impacts further.”

Intelligent redundancy with machine learning and AI
For maximum data center uptime, integrated energy storage overcomes unreliable mains or the intermittent nature of many renewable energy sources, supporting energy-neutral operations.
Most data centers today run on AC distribution. However, DC grids offer exciting opportunities for easy integration of alternative energy or redundant power sources. Danfoss solutions ensure reliable power conversion in smart distribution grids and DC grids with energy storage. Peak shaving using energy storage smooths the peaks and troughs, so the grid supply can operate consistently at the average power demand, which is usually relatively low.
Danfoss solutions support you in power usage effectiveness (PUE), minimizing power distribution losses by performing power conversion in as few steps as possible, and by keeping high voltage close to the load.
Innovative and economic redundant systems from Danfoss ensure consistently reliable supply. Our inventive solutions for redundancy significantly reduce capital investment. They also facilitate transmission of relevant data for increasingly complex power management systems which use artificial intelligence and machine learning to optimize efficiency (PUE). It’s about sharing expert knowledge between the right people to make sure the combined hardware-AI system is an ongoing success. When you deal with Danfoss, this knowledge sharing is always part of the package.
Danfoss solutions also facilitate intelligent and reliable back-up supply in the event of power outage to the data center, ensuring Tier 3 or Tier 4 protection for stable operation of servers and systems.
Features and benefits
- Resistance to mains interruptions with energy mix in smart grids combining renewables, energy storage, and cogeneration with liquid natural gas (LNG)
- High lifetime PUE and redundancy with DC grid distribution solutions
- Economic power conversion microgrid solutions based on renewable energy and energy storage
- Pre-certified grid compliance using air-cooled or liquid- cooled technology
- Knowledge sharing is always part of the package

Efficient fire safety in data centers
Danfoss high-pressure water mist systems are FM Approved for fire safety in data centers. Known as SEM-SAFE®, these high-pressure water mist systems are suitable for protecting an entire mission-critical data facility, including double tier cable trays, data processing equipment rooms or halls, and sub-floors.
SEM-SAFE® systems comprise a high-pressure modular pump unit, section valves, piping, and water mist nozzles. The pump unit has a compact design, low weight, small footprint and an easy configuration to fit the data center’s need for expansion.
SEM-SAFE® high-pressure water systems use water micro-droplets released through the nozzle into protected areas. An ultra-fine mist is formed with a two-fold extinguishing effect. In addition to cooling the flames, it simultaneously starves the fire of oxygen. The cooling effect also lowers the risk of re-ignition, protects against heat damage, and hinders fire spreading.
Features and benefits
- Minimum downtime
- Minimum water damage
- Low water consumption in comparison with traditional sprinklers
- Instant cooling in the fire zone
- Ventilation can be kept running
- No need to keep the data center airtight
- Lower total cost of ownership with no refill cost and maintenance-free pumps
- Risk of false discharge is minimized
- Sustainable fire safety technology
- Suitable for modular data centers
- Small pump and water tank footprint, thus no need for large storage as in the case of gas cylinder
