Why data centre humidity must be controlled

Data centres are large halls housing computer systems and information storage equipment. The value of equipment in data centres – and that of the information stored on it – means that it must be protected properly. Along with temperature, humidity is a major concern and we’ll explore the reasons why here.

If humidity levels in a data centre are too high, airborne water may condense on internal components and cause corrosion. This will eventually lead to a system failure and could destroy data. On the other hand, if humidity is too low then the risk of electrostatic discharge (ESD) increases, which may result in devices being irreversibly damaged.

ASHRAE’s ‘Thermal Guidelines for Data Processing Environments’ recommends that data centres have a maximum relative humidity of 60%, with lower and upper dew point temperatures of 5.5°C and 15°C respectively. Consistency is key, and maintaining a stable level of humidity takes reliable, controllable humidification equipment.

Gibbons’ humidifiers are ideal for data centre applications, as they may be integrated into an existing HVAC system or installed as standalone units. Our rotary atomiser system distributes an ultra-fine mist which evaporates into the passing air, making it an effective energy-saving replacement for steam humidifiers. The reduced maintenance costs mean some customers pay for their Gibbons humidification system in less than 12 months.

So for data centre humidification systems, look no further than Gibbons. Our expert team can manage every stage of your installation, with servicing, maintenance and repair available too. Call Steve Rix on 07966423165 or email for technical advice and a quote.
