Our gas extinguishing systems are designed for areas where water-based suppression is not ideal, such as data centers, server rooms, and archives. These systems use clean agents to extinguish fires quickly and efficiently without damaging sensitive equipment.

CO₂ Systems

Description

Carbon dioxide is a plentiful, non-corrosive gas that does not support combustion nor react with most substances. It has a low toxicity classification by Underwriters Laboratories (Group 5a). It is commonly compressed to the liquid state for storage and transportation in ISO 9809-1 cylinders. 

Upon release, it discharges under its own pressure giving the appearance of steam as its low temperature crystalizes water in the air. For fire suppression purposes the discharge is designed to raise the carbon dioxide concentration in the hazard area. This removes the free oxygen which supports combustion, and results in fire extinguishment. 

The resultant lack of free oxygen dictates that total flooding hazard areas be evacuated immediately, and carbon dioxide from local application be avoided by personnel.

Applications

Carbon dioxide extinguishing agent used in engineered systems is particularly useful for hazards where an electrical, non-conductive medium is essential or desirable; where clean-up of other agents presents a problem; or where the hazard obstructions require the use of a gaseous agent.

The original "clean" agent, carbon dioxide suppresses fire without leaving behind an agent to damage sensitive equipment. And because there is no agent to clean up, you’re back in business faster. To provide the most economical system arrangement without sacrificing performance, we offer both Total Flooding and Local Application, high pressure systems (excluding distribution pipework and fittings).

Halocarbon Gas Systems (HFC227ea, FK-5-1-12)

Description

Red G’s chemical gas systems are provided with the option of TWO clean agent fire suppression systems that protects high value assets from fire and the effects of fire-fighting, allowing normal operations to be resumed quickly with no collateral damage and clean-up costs.

HFC227ea and FK-5-1-12

Chemical gas extinguishing systems are fast and effective with a low space/weight characteristic which is also environmentally acceptable and safe for human exposure.

HFC227ea

is classed as a clean agent which means that it is safe to use within occupied spaces. The safety of HFC227ea fire suppression environments is proven in over a decade of real-world experience and validated by extensive scientific studies. These systems take up less storage space than inert gas systems.

In addition, HFC227ea does not deplete stratospheric ozone, and has minimal impact on the environment relative to the impact a catastrophic fire would have. This fire suppression solution is already working in more than 100 thousand applications, in more than 70 nations around the world.

FK-5-1-12

FK-5-1-12 protects property against water damage caused by automatic sprinklers. This fire suppression gas is extremely environmentally friendly because its atmospheric life is only up to 5 days. So you do not only get to reap the benefits of an environmentally friendly fire suppression agent, but you will also have peace of mind that you’re equipping your facility with a green firefighting fire suppression agent.

FK-5-1-12 fire suppression agent is non-conductive, residue free and non-corrosive. In the case of a fire emergency, you will know there’s a fast acting fire suppression agent on hand that will protect life and property without harming ozone layer as FK-5-1-12 has an ozone depletion potential of zero. If you are curious about the speed of the Novec1230 agent, it’s a clean agent that can discharge and fire extinguish within 10 seconds. This clean agent takes up very little space in comparison to CO2 systems.

Applications

Chemical agents are designed to suppress fires in Class A, B and C hazards. Chemical agents suppress fires by physical means and with some chemical means.

Chemical agent fire suppression systems are particularly valuable in extinguishing fires in enclosures containing hazards or equipment where a clean, electrically non-conductive medium is essential or where the cleaning up of foam, water or dry chemical would be a problem.

Approvals

Red G gas suppression systems have VdS, UL and FM component approval. And exceed the criteria for VdS design approval.

Ansul INERGEN® Systems

Description

INERGEN® agent is nontoxic, does not produce corrosive decomposition products when exposed to fire and is designed to protect valuable or sensitive assets that could be damaged by conventional agents. When discharged, it will not produce a fog, so escape routes will remain visible. And in the aftermath of an incident, the agent simply returns to the atmosphere in its natural state causing no environmental impact.

Applications

INERGEN® is ideal for manned areas where other agents cannot be used due to their toxic nature. It can be used on Class A and B fires and is widely used in areas containing sensitive electronics.

Approvals

Ansul Inergen comes with approvals from UL, FM ,NFPA, ISO as well as the EPA.

• Automated Tape Storage Libraries
• Computer & Data Processing Facilities
• Cultural & Historical and Major Medical Facilities
• Marine/Offshore/Naval
• Museums & Art Galleries
• Power Generation Facilities
• Telecommunication Facilities

Additional Information

200 Bar Systems

Upon discharge, INERGEN® instantly floods the room, remaining suspended to suppress fires quickly and effectively. An inert gas mixture, INERGEN® is absolutely free of residues and corrosive by-products that may produce further property damage. INERGEN® is designed in accordance with ISO 14520 part 15 with documented extinguishments of 22 seconds for a Class A fire and 17 seconds for a Class B fire.

Reliable and field proven, INERGEN® delivers the performance you would expect from the world leader in fire suppression.

With INERGEN®, the oxygen level is reduced enough to put out the flames, yet more than enough remains to breathe. In fact, those who breathe normally around INERGEN® in extinguishing concentrations receive the same amount of oxygen to the brain as they would in an ordinary atmosphere, vital in cases where immediate evacuation may not be possible.

INERGEN® agent is stored as a gaseous mixture in DOT approved steel cylinders, you can choose to install your cylinders either vertically or horizontally, allowing for a design that requires the fewest number of cylinders and the lowest cost. You then have a choice of setting up your cylinders to open electrically, pneumatically or manually, depending on your need.

300 Bar iFLOW Systems

Using innovative iFLOW delivery technology, the INERGEN® 300-Bar Clean-Agent Fire Suppression System provides a regulated agent discharge into the protected hazard area.

During a typical inert gas system discharge, peak pressure and flow spikes occur. It is these peaks that are used to determine the pipe size specification and venting requirements. The iFLOW system reduces pressure spikes in the distribution pipe network during discharge. This allows for the use of smaller diameter, lower pressure-rated piping and reduced pressure relief venting requirements. An enhancement to the proven agent technology, the innovative iFLOW technology is based on three main elements:

The iFLOW valve reduces the peak pressure and regulates the flow at a nominal pressure of 60 bar (870 psi) in the 300 bar (4350 psi) system, while maintaining the ability to achieve 95% of the system design concentration within 60 or 120 seconds

The iFLOW horizontal check valve minimizes installation time by facilitating the interconnection of containers and, in many cases, eliminates the need for a discharge manifold

The iFLOW matrix system offers design flexibility and adaptation to complex architectural spaces. When compared with traditional racking, the matrix system allows storage containers to be positioned in traditional rows or around objects providing more flexibility during installation and quicker removal of containers from the bank during recharge and maintenance
