Tyco are a leading inert and chemical gaseous fire suppression systems provider whose “track record” for providing “long term sustainable” gaseous fire suppression systems remains unbeatable and beyond reproach.

We have achieved this recognition by ensuring that the “working life” of all the different types of gaseous fire suppression systems that we provide has been safeguarded against replacement from potential future changes in Health & Safety and Environmental Legislation.

Tyco have been committed to the continued development of six types of inert and chemical gaseous fire suppression system.

As a result, during the past forty years, we have protected virtually every type of “Business/Process Critical Area” on land, at sea and in the harshest of environments imaginable.

Our continued success is reflected by the large number of global partnerships we maintain with some of the world’s top 100 companies within the industrial, commercial, marine, oil & gas and power generation market sectors.


Carbon Dioxide (CO2) , the original ‘gaseous fire fighting agent used’ in fire protection, is a naturally occurring compound with no measurable environmental impact, making it ideal for non-occupied spaces that can be totally flooded with a gaseous fire suppression system for maximum effect.

As a by-product of manufacturing processes CO2 is collected, stored and processed for use as a fire suppression solution, is an economic alternative for protecting numerous industrial applications providing personnel are trained in the hazards, safety precautions and operation of CO2 systems during and after discharge.

CO2 is lethal at high concentrations and must not be used in occupied areas or areas where human exposure is possible.


INERGEN is a mixture of three inert, naturally occurring gases: 52% nitrogen, 40% argon, and 8% carbon dioxide. As INERGEN is derived from gases present in the earth’s atmosphere, it exhibits no ozone depleting potential, nor does it contribute to global warming.

INERGEN gas suppresses fire by lowering the oxygen content below the level that supports combustion. When INERGEN is discharged into a room, it introduces the proper mixture of gases that still allows a person to breathe in a reduced oxygen atmosphere. It does not produce a fog when discharged and escape routes remain visible.

Inergen to date is the only gas suppression agent which has been tested and proved to be safe on humans.

The following are typical hazards protected by INERGEN systems: Computer rooms, Data centres, Tape storage, Telecommunication sites, Control rooms, Vaults, Process equipment, Museums, Art galleries, Archives, UPS switchgear, Other industrial risks

INERGEN Using i-Flow technology

i-Flow technology is designed to be applied to the whole range of inert gases used as environmentally friendly fire fighting agents in fire suppression systems.

i-Flow systems eliminate the peak pressure point and achieve a balanced, constant flow during release.

The patented i-Flow valve regulates the flow at a pressure of 60 bar, whilst maintaining an ability to achieve a discharge of 95% of the gas within 60 seconds.

i-Flow technology explained.

iFlow Proessure Profile Chart
iFlow Pressure Profile Chart

Curve A shows a standard high pressure inert gas system discharge, with it’s distinctive peak flow and pressure spike which requires larger and higher specification pipework and greater venting area.

Compare this with Curve B which illustrates that the peak flow and pressure spike has been eliminated and a more even flow achieved during the entire effective discharge period. This is the i-Flow technology, working to provide a superior fire suppression solution.


FM-200 works by removing the element of heat from a fire thus ensuring combustion is interrupted.

FM-200 has proved to be the most widely used replacement for Halon 1301 with zero ozone depleting potential.

FM-200 is non-conductive so there is no risk of thermal shock to sensitive electronics, it suppress fire without consequential damage and is the system of choice in thousands of facilities around the world.

Sapphire / Novec™ 1230

Novec™ 1230 is the active component of the Sapphire System.

It is a liquid at room temperature allowing it to be transported economically and without restriction.

Research has shown that due to the speedy atmospheric degradation on discharge of approximately 3-5 days, the Global Warming Potential (GWP) of Novec™ 1230 is 1 (relative to CO2), for practical purposes negligible.

Benefits of Gaseous Suppression

  • In the event of discharge, the agent is cost effective to replace

  • No evacuation issues

  • Cylinders can be remote from the risk (up to 100m)

  • Directional valve solutions to enable mutli-risks to be protectede conomically using single cylinder bank

  • Constant flow solution available, therefore reducing size of venting requirement

  • Reduced venting requirement compared to Inerts

  • Future proof – no risk of being banned

  • Used in manned environments

  • Greenest Chemical

  • Venting requirement reduces

  • Economical installation costs

  • Compact storage and space sufficient

  • Can be stored within the risk

  • Low cost pipework

  • Economical installation
