Data center cooling system and technologies

Reduced pump downtime and increased cooling process reliability

- Variable speed drives' supervisory functions warn about potential imminent mechanical failures like bearing wear

- Smart sensors measure vibration and temperature for pump performance monitoring, enabling efficient maintenance planning

Optimized energy consumption

- Variable speed drives bring big energy savings for pumps: Running 1/2 speed requires only 1/8 the power

Eliminate pressure shocks that damage pumps, seals, pipe joints and valves

- Soft Start-and-Stop function in the drive helps avoid pressure peaks and water hammer helps avoid pressure peaks and water hammer

Protection against pipe leakage or pipe blockage

- Variable speed drives can identify abnormal pressure peaks and drops in pipes, and then send an alarm or shut down the system

Reduced fan downtime and increased cooling process reliability

- Variable speed drive protection includes over-current, over-voltage, motor over-heating and over-load control

- Smart sensors collect information on fan bearing performance enabling predictive maintenance

Optimized energy consumption

- Highly efficient motor-drive package with efficiency above IE4/NEMA super premium

Eliminate power quality problems

- Ultra-low harmonic drives keep harmonics content in the data center network to a minimum

Cooling process maintenance

- Control of airflow and cooling liquid flow

- Maintenance of required humidity level through controlling fans /control valves in humidification equipment

- Filter condition monitoring and clogging alarm

BMS control reliability

- Control backup in variable speed drives. In case of external communication loss, variable speed drives can take over control

Smooth restart in case of power loss

- Auto restart feature allows variable speed drives to restart automatically after a short power supply failure

Smoke management and fire protection

Optimized energy consumption

- Highly efficient motor-drive package with efficiency above IE4/NEMA super premium

- Interlinking of compressor control with condenser water pump and cooling tower fan for optimized efficiency

Eliminated power quality problems

- Ultra-low harmonic drives keep harmonics content in the data center network to a minimum

Resonance control

- Variable speed drives' resonance control feature reduces vibration which can lead to premature failures and negative acoustic effects

Compressor control optimization

- When heat load cannot be covered by a running compressor, new compressor starts

Ultimate reliability of compressor operation

Avoiding gearbox failures, oil leaks, misaligned drive shafts and vibration 

- A direct drive motor and drive package for cooling towers eliminates the need for a gearbox and other associated components

Humidity maintenance to avoid static discharge

- Variable speed drives maintain required humidity level by controlling pumps and valves in humidifiers, thus avoiding dangerous static discharge
