Maintenance free fire suppression for mission critical datacenters and electrical hardware

Ref-Nr:

Technology abstract

A Dutch company developed a fire suppression technology based on cool gas generator technology. This technology was originally developed for use in satellites and is therefore completely maintenance free. Cool nitrogen generators can easily replace pressurized gas cylinders containing nitrogen that are currently used in fire extinguishing systems. The Dutch company seeks contacts with ICT manufacturers and fire suppression system producers that are interested in license agreements.

The Cool Gas Generator is a unique way to produce different types of gas out of a solid material (grain). By starting the gas generator the solid charge is decomposed and the gas is released. Due to the innovative propellant and design, pure gas is produced at ambient temperature. A Cool Gas Generator can produce Carbon Dioxide, Nitrogen, Oxygen (pure, MAC TGG8 for human use), Methane, Hydrogen or High Yield Gas.

Technology Description

The Dutch company develops and manufactures cool gas generators for fire suppression. These systems do not contain a pressurized gas. Instead, the gas is chemically stored in a solid form. A cool gas generator delivers pure gas at ambient temperature through decomposition of this solid material. Cool gas generators can be applied anywhere where (pressurized) gas is needed. They are especially suited for applications were the gas needs to be stored for a long time before being used. Originally gas generators were developed as propulsion systems for positioning of satellites. But they are also suitable for applications like inflation of emergency systems, mechanical actuation systems and in harsh environments, e.g. bio hazard areas or military field applications (army, navy and air force). For fire suppression in datacenters and electrical hardware a dedicated version of a nitrogen producing gas generator was developed. This technology can replace pressurized gas cylinders in gaseous fire extinguishing systems. The generator is mechanically activated and requires no external energy sources.

Innovations & Advantages

  • The device produces nitrogen at room temperature, i.e. a few degrees above the actual temperature of the generator itself. In this way the temperature shock that other gaseous fire extinguishing systems usually produce, is avoided.
  • Furthermore, the nitrogen is stored without pressure. Hence, there is no loss of pressure over time and the device is completely safe because it cannot explode due to external fire.
  • By releasing nitrogen at low pressure, any additional damage to the ICT equipment is avoided. Furthermore it requires less expensive installation and maintenance costs than current gaseous fire extinguishing systems.
  • Compared to the existing compressed gas bottles storage technology, the proposed technology has a lower volume, is flexible in positioning and integration in existing structures.
