Fire Suppression for Micro Data Centres

A micro data center (MDC) is a small-scale modular data center that includes all the compute, storage, networking, power, cooling, and other infrastructure required for a given workload.

Micro data centres help IT professionals install and manage edge networking and computing simply, reliably, and predictably by combining power, cooling, physical security, and management software and services into prepackaged rack solutions that can be deployed globally in any environment.

What Solutions are available?

Highly sensitive smoke detectors such as VESDA HSSD or Carrier Modulaser can detect even the lowest smoke concentrations which may be caused by a malfunction of an electric or electronic element, for example. In the event of a fire, the fire protection system needs to react reliably and appropriately, triggering a coordinated alarm which leads people out of the danger area and activates extinguishing systems.

An automated extinguishing system can provide the best protection for sensitive electronic equipment – with specially designed nozzles not impacting on computer hard disk drives and people safe, environmentally friendly extinguishing agents. We have an article on reducing the noise in a fire suppression discharge here.

What options are there for fire suppression systems?

Inert gas fire systems once activated lower the oxygen level in the room to a point where the fire is extinguished but is safe for you and your employees.

Commonly used inert gasses for server or comms rooms are IG-55 (Argonite®). IG-55 is an inert gas blend of argon and nitrogen, which occur naturally in the environment. With zero ozone depletion potential ODP, zero Global warming potential GWP and zero atmospheric lifetime, it has excellent environmental properties. A typical design concentration of 40% will reduce the oxygen level to 12.5% within 60 seconds.

Another gas is IG-541 (Inergen®). IG-541 is a mixture of 52% Nitrogen, 40% Argon and 8% CO2. However, in the event of a fire, when IG-541 is discharged, it mixes with the air present in the room to create a mixture that comprises of 67.3% Nitrogen, 12.5% Oxygen, 17% Argon and 3.2% Carbon Dioxide. As with IG-55, the mixture of gasses will reduce the oxygen levels down and extinguish the fire and will be safe for people within the room.

Nitrogen is inert gas naturally present in the atmosphere consisting of 100% Nitrogen, therefore its green-house effect is nil and its ozone layer depletion potential is zero. It is chemically inert, non-conductive, colourless, odourless and flavourless. As with IG-55 & IG-541, Nitrogen gas systems will reduce the oxygen levels down and extinguish the fire and will be safe for people within the comms or server room.

Synthetic gas systems quickly extinguish the fire once activated; they are designed to extinguish the fire in under 10 seconds.
