How dehumidifiers play a vital role in data security

Data centres can have thousands of powerful servers running day and night to provide storage, backup, recovery and security for enormous amounts of information.

The hardware that makes this possible is usually stored in one centralised location and can span rooms, entire buildings or multiple facilities.

In every case, the environment inside a data centre needs to remain at a constant to avoid the risk of overheating and condensation damage to sensitive equipment such as motherboards, hard drives and connecting sockets.

Preventable outages and unplanned downtime mean extra cost, loss of business and lots of work to get equipment back up and running as quickly as possible.

Temperature and humidity are linked

Cooling systems are essential for keeping equipment from overheating in data centres, but when an operator fails to control humidity levels, moisture will remain in the atmosphere. This causes condensation to form and this increases the risk of equipment failure.

Because warm air is capable of holding more moisture than cold air, humidity levels will increase as a room heats up. The amount of moisture that the air can hold at its current temperature is measured in relative humidity (RH) as a percentage.

So, as the temperature increases, moisture in the room and damp air from outside ventilation will build in the atmosphere. When the air is cooled and limited in the amount of moisture it can hold, the RH level will continue to rise until it reaches 100 per cent or ‘dew point’. This is when the moisture in the atmosphere is released in the form of condensation.

Benefits of condensation dehumidifiers

Efficiency is often a deciding factor for many data centres as, on average, cooling and power supplies count for up to 43 per cent of energy costs. For large data centres, we usually recommend a high-capacity condense humidification solution.

Some of the key benefits of commercial dehumidifiers for data centres include:

  • Remove moisture much more efficiently than a computer room air-conditioning (CRAC) unit
  • Achieve less than half the power consumption of other dehumidification technologies
  • Straightforward installation
  • Low capital cost
  • Minimal heat carry-over to the data centre suite
