Humidification for Data Centres

Data Centre Humidification Systems

Controlling Humidity in Data Centres

Humidification is the artificial regulation of humidity in the environment. When the atmosphere in your data centre becomes too dry, moisture is drawn from surrounding materials, which has a detrimental effect on your data centre performance. Low relative humidity is not only uncomfortable, it can also be damaging to equipment and materials.

Sonicom Fogging Nozzle

The Sonicom fogging nozzle is ideal for increasing the level of relative humidity within a data centre by introducing moisture back into the atmosphere without causing wet areas or excessive water drop out.

Ultra-fine fogs

Ultra-fine fogs down to only 1 micron (0.001mm) are possible, therefore ensuring the soft plume of water droplets remain in suspension until evaporation takes place. When complemented with our special water valve assembly, the unit becomes a highly efficient non-drip, self-cleaning atomiser.

Heavy Duty Stainless Steel Water Valve

The heavy duty stainless steel water valve is controlled by the same compressed air supply used to activate the nozzle. A simple on/off signal is required to activate the system and when he signal is removed, the water valve self-cleans every time the nozzle is turned on/off, it does not drip meaning there is no risk of having a blocked nozzle, allowing for use in environments where control is essential and access limited.

Sealpump Control Panel

Nozzles are controlled by a Sealpump control panel, which switches the system on/off automatically to provide the stable humidification levels required. Sealpump can work with you to design a highly efficient Dry Fog humidity control system with controls that can link into existing processes in your data centre.

The Dry Fog humidification systems provide an economical, low maintenance and low energy consuming humidity control solution, capable of achieving up to 99% rh.

Merlin Humidification Systems

Merlin Technology’s range of Air Humidification systems are perfect for controlling the relative humidity in data centres and the electronic industry.

Two of the main issues faced are from electrostatic charges and the potential of electrical discharges. Well designed and controlled humidity control can solve these issues.

Problems caused by low humidity in the electronics industry include:

  • Change in material properties
  • Increase in electrostatic charge
  • Increased dust particles which effects components
  • Increased equipment maintenance and downtime

Optimal Humidity Creates:

  • A reduction in static charge
  • Reduced dust levels
  • Lowers fire risk
  • Creates a better working environment for staff

Whether through a direct room humidity control system or a duct mounted system, we have the correct system to create the best environment.
