Gaseous fire suppression

Gaseous fire suppression is a term to describe the use of gases and chemical agents to extinguish a fire. These Agents are governed with different standards and regulations in the world. The system typically consists of the agent, agent storage containers, agent release valves, fire detectors, fire detection system (wiring control panel, actuation signaling), agent delivery piping, and agent dispersion nozzles.

Gas Flooding System features:

  • Gas Flooding System Rapid discharge.
  • A flexible range of cylinder sizes.
  • Solenoid, mechanical and pneumatic actuation.
  • Solid brass valve construction for durability.
  • A versatile range of nozzles for easier system layouts.
  • Effective on-site installation.

Designed to withstand every climatic conditions, these devices are widely used in following area of applications: 

 

  • Transformers Control Rooms
  • Power Generators
  • Machinery Spaces
  • Electrical Rooms & Equipment’s
  • Chemical Stores & Chemical Equipment
  • Switch Rooms

Types of Gas Flooding System:

• Co2 GAS Suppression  • FM200 GAS Suppression  • NOVEC GAS Suppression

 

Co2 GAS Suppression

CO2 at atmospheric pressure is a colorless, odorless and electrically Non-Conductive inert gas. It has high expansion ratio, which facilities rapid discharge and allows three dimensional quick penetrations in the entire hazard area. Made from premium components, this CO2 Gas Flooding Systems importance lies in the fact that it has high efficiency to extinguish fire by reducing the oxygen content of the protected area below the point where it can support combustion. This CO2 Gas Flooding System provides a blanket of heavy gas that reduces the oxygen content of the atmosphere to a point where combustion is not sustainable.

Applications:

Modern, more efficient equipment makes use of carbon dioxide to displace intra cardiac gases in a safe procedure. The carbon dioxide field-flooding technique is safer, easier, and more efficacious than tradition. Used for machinery spaces, pump rooms and cargo holds, the CO2 by suppressing the oxygen content in the space. From main distribution valves, a piping system is used to distribute the gas to the discharge nozzles, which are placed uniformly throughout the protected CO2 extinguishing system is a total flooding system designed to use in engine rooms, pump rooms and cargo holds. It extinguishes fires using Co2 by suppressing the oxygen content in the space.

Features & Benefits:

  • Fast fire extinguishing system
  • Effective on deep-seated fires in engine rooms, pump rooms and cargo holds
  • Safety release delay designed for security Effective on deep-seated fires in engine rooms, pump rooms and cargo holds
  • Co2 gas is cost effective.

 

FM200 GAS Suppression

Gas Suppression Systems (FM200) is a reliable solution based on HFC 227ea, an extinguishing agent known around the world. Built on 42-bar technology, these Gas Suppression Systems are efferent and space saving. Whether for the valuable systems, data, people or the working environment, this Gas Suppression System provides optimum protection in case of fire and helps ensuring business continuity. The extinguishing agent of this Gas Suppression System is very effective and works at low extinguishing concentrations to protect people and assets. The extinguishing agent is chemically inert and has low electric conductivity. This Gas Suppression Systems provides ideal protection especially for areas with electrical and electronic risks of fire. Extinguishing without leaving any residue and without risking of corrosion is found in this Gas Suppression System.

Features:

  • Reduces risk of downtime and helps maintain business continuity in the event of a fire.
  • Clean - Leaving no residue.
  • Safe for discharge into occupied spaces Design concentrations for 95% of its applications fall well below NOAEL levels
  • Cost effective engineered system, providing maximum protection
  • Sustainable technology providing an environmentally friendly solution.

Technical Specifications:

  • FM-200 agent actively attacks the fire to extinguish flames rapidly
  • Engineered system providing a fast acting 10 second discharge
  • Offers full-developed, flexible design limits to fit any application environment
  • Design concentrations range from 6.25% to 7.0% for Class A and Class C hazards
  • Easily designed using engineered series software

NOVEC GAS Suppression

NOVEC is an innovative solution that reduces the risk of fire damage in critical applications and sensitive equipment. At a proper system design concentration, the extinguishing agent NOVEC Fire Protection Fluid absorbs sufficient heat to upset the balance of the fire. This cooling effect is supported by the oxygen reduction in the flame due to the volumetric expansion of the molecules. The high efficiency of the NOVEC system allows using a low extinguishing concentration. As a result, the user needs to store only a relatively small amount of the extinguishing agent to safely protect rooms. Additionally, the minimum 10 bar at the nozzle concept used by Siemens ensures fast and full evaporation of the NOVEC fluid, minimizing extinguishing times. Compact system designs are possible as NOVEC works with the NOVEC fluid, offering the lowest design concentration of all currently authorized extinguishing agents. Fewer cylinders and less space are needed for installation and storage because the liquid agent NOVEC fluid is stored in cylinders pressurized with 42- bar nitrogen.

Highlights:

  • Manufactured using high-pressure technology
  • Allows higher design flexibility and enables the realization of larger and more complex piping networks compared to low-pressure systems.
  • Special software comes installed that precisely calculates the ideal layout of the piping network, so the clients get an optimal solution tailored to their individual needs.
  • Can easily be adapted to existing ones with few alterations.
