Leading Electrical and Power Cooling Efficiency

Electrical and cooling systems have been designed with highest possible energy efficiency in mind. The result is an outstandingly good energy efficiency for a Tier IV facility, with a PUE (Power Usage Effectiveness = Useful IT kW / Totally used kW) as low as at 1.15. This is achieved by highly innovative designs in power and cooling systems.

Here are some examples of how we achieve our oustandingly good PUE.

Hi-Tech Cooling Fans

We use continuously adjustable direct drive EC centrifugal fans to cool our data centers based on actual cooling needs to save energy. Fan blades have an aerodynamically optimized shape that reduce power need and noise.

Variable Speed Compressors

We use highly energy efficient and
environmentally friendly variable speed compressor with magnetic bearings for cooling in the warmest summer days. They use refrigerants with a very low Global Warming Potential (GWP) in the atmosphere.

Variable Frequency Drives

Variable frequency drives are deployed in water pumps in our cooling systems to save energy by automatically reducing motor speed and power draw to match lower system loads. Redundancy in pump groups also allow lower speeds.
