Crossfire Group Ltd specialise in the design and installation of fire suppression systems, and offer our clients expert guidance and support in selecting the right system for you.
Our teams work closely with clients to understand operational requirements, tailoring a bespoke system to your exact needs. We deliver two different types of fire suppression systems comprising of ‘Inert’ and ‘Chemical’ systems.
Inert Gas Fire Suppression systems work by removing enough Oxygen in the room to extinguish a fire, whilst leaving enough for humans to survive in. Inert gases are colourless and odourless, safe for people, the environment and cause no damage to property or data. Inert Gas systems include:
INERGEN (IG541) – is a rapid extinguishing agent which uses naturally occurring gases, Argon, Nitrogen and Carbon Dioxide (chemical compound designation IG541). It provides a suitable suppression across occupied buildings, as it operates perfectly safe for human exposure at the system design concentrations. It is stored at 300 BAR pressure as a gas in standard size cylinders. The INERGEN system is discharged through a piping network into the protected area.
INERGEN systems extinguish a fire by reducing the oxygen content from approximately 21% found in ambient air to 15%, a level at which most combustible materials will not burn. Simultaneously with this, carbon dioxide is released to assist the human body to inhale and absorb oxygen, ensuring a safe level of oxygen exposure is maintained.
Benefits:
ARGONITE (IG-55) – is an inert gas mixture consisting of 50% Argon and 50% Nitrogen. This type of system can be used as total flooding suppression against the most flammable substances. IG-55 suppression can be used to protect a wide range of applications from sensitive electrical equipment to industrial applications. Storage cylinders are manufactured using high grade alloy steel, and systems operate at 300 bar pressure. Gas cylinders can be stored in excess of 100m from the protected area. The gas protected area should be sealed professionally to be able to retain the design concentration of the system, if discharged in a fire condition.
IG-55 systems extinguish fires by reducing oxygen levels below combustion rates between 10-15%, compared to ambient air at 21%. At this level, humans will be able to breathe normally, whilst a fire is being distinguished, ensuring a safe environment is maintained.
Benefits:
IG-100 (Nitrogen) – IG-100 uses Nitrogen for a clean, safe and 100% ecological extinguishment of a fire. This gas is widely used in a variety of extinguishing systems due to its excellent pressurisation conditions. It is ideally recommended for class A, B and C hazards. The system operates by total flooding of the room, ensuring discharge in less than 1 minute.
IG-100 works by reducing oxygen levels to extinguish the fire, while leaving a percentage of oxygen suitable for occupied areas, for safe evacuation. Nitrogen is a clean gas, and generates no combustion products, and does not cause irritation to the skin and eyes, so is ideal for extinguishing fires in occupied spaces.
Advantages:
Dry chemical fire suppression systems distinguishes fires rapidly, and offers total coverage, making them the industry standard for heavy equipment applications. They provide fire protection against class A (debris), class B (fuel) and Class C (electrical) fires. This system is effective by flooding a volume of space, such as a vehicle engine compartment, with a firefighting agent to suffocate the flame. Chemical systems include:
FM-200 Fire suppression – FM-200, also known as HFC-227ea, is a clean agent fire suppressant for Class A, B, and C fires and meets NFPA Standard 2001 Clean Agent Fire Extinguishing System. Clean agents are fast and effective in suppressing fires, safe for use in occupied areas, and do not leave any residue.
FM-200 suppresses a fire by disrupting the fire triangle (heat, oxygen, and a fuel source). By removing one of the elements within the fire triangle, the fire is extinguished. Clean agent fire suppression systems can achieve fire extinguishing concentrations in 10 seconds or less. Leaving no residue or deposits behind, the FM-200 system is ideal for areas with equipment, electronics and machinery.
Benefits:
NOVEC 1230 – is a fast, clean and environmentally friendly clean agent. It is suitable for the protection of enclosed, occupied areas where personnel safety is paramount. It is stored under pressure as a liquid with nitrogen as the propellant gas.
The Novec 1230 agent is discharged through a piping network into the protected area. Novec is an excellent extinguishing agent suitable for your communication rooms, server rooms, and large Data Centres.
Advantages:
Firetrace – a self-activating fire suppression system without the need of any external power supply. It is made up of flexible patented linear heat/flame detection tubing, that can be applied to almost any object/application, regardless of size.
A cost effective, robust and versatile fire suppression system that is absolutely safe against malfunction. It can be provided as a direct system to extinguish the closest point of the fire and Indirect system to extinguish into a protected area.
Kitchen suppression – we offer a range of kitchen fire suppression systems, to cater for a variety of facilities including:
