Marine GX-20 / FM-200®Fire Extinguishing System
Protection made to measureFor a long time Halon was regarded the most effective fire extinguishant for various fields of application. Due to its harmful influence on the ozone layer Halon can not be utilised in Europe since 2003. Halon is now succeeded by FM-200® extinguishants. FM-200® is fast and effective, requires little storing space and has a low floor load. Next to this, FM-200® is environmentally friendly and safe to humans when exposed. Ajax Chubb Varel supplies the GX-20 system that extinguishes with this effective FM-200®.
Highly effective agentFM-200® is a colourless, odourless gas containing only carbon, hydrogen and fluorine; lacking the ozone-depleting presence of bromine atoms. Highly penetrative in the hazard zone, it acts on fires largely by physical means, lowering the temperature of the flame and fuel to a point at which combustion reactions cannot be sustained. There is no significant obscuration on discharge, no postdischarge clean-up, and no damage to sensitive equipment.
Environmentally friendlyFM-200® has zero ozone-depletion potential and is accepted for use by the US EPA (Environmental Protection Agency) plus many other approval bodies. FM-200® mitigates the effects of an uncontrolled fire and at the end of the lifetime of the system, the gas can be readily recovered and recycled.
Rapidly prevents fire and smoke damageThe Ajax Marine GX-20 system comprises of a versatile line of cylinders, valves and related components which have been selected and approved for use in the marine environment and have been subject to stringent testing procedures. Flexibility, quality and reliability make the Ajax Marine GX-20 system the world’s finest in fire safety.
Engineered systems offer optimum designs for defined risks with reduced pipe sizes, unbalanced flows and multiple compartment protection.
Systems are designed in accordance with the manual to achieve a minimum FM-200® concentration of 8.7% for diesel fuel with a maximum discharge time of 10 seconds.
As a result, a GX-20 system provides rapid fire protection, strictly limiting fire and smoke damage.
Minimal storage spaceFM-200® is stored as a liquid in nitrogen-pressurised containers at 25 bar, leading to minimal storage space requirements comparing favourably with all other viable gaseous agents.

Assured reliabilityAjax Chubb Varel Marine systems are designed to conform to NFPA 2001 and tested to limits established by the International Maritime Organization (IMO). An empirically-verified Windows™-based computer program is used to model two-phase agent flow and ensure that the correct concentration of agent is achieved within 10 seconds throughout the protected zones as required by flagstones and classes.
ApprovalsOur Marine GX-20 systems are approved, qualified under, listed or meet the requirements of various national and international specifications and standards. Further information is available on request.
Actuation componentsGX-20 valves are designed for maximum performance and low installation costs. The fast-opening valves are available in a range of sizes and are manufactured from tough, corrosion-resistant brass under stringent quality control standards. An easy-to-read gauge on the valve permits the convenient visual inspection of the cylinder pressure.
GX-20 valves are actuated by the following means:Remote cable release direct to agent container•Pressure actuation using slave FM-200® cylinder or pilot cylinder •with local actuationManual local actuation on FM-200® cylinder valves•Time delays and pre-discharge alarms are also available.•
All related components from discharge nozzles to control heads are designed to be compatible, allowing a complete system to be configured using DNV, GL, LR and MED approved equipment.
Wide range of cylindersA wide range of sizes are available, offering a choice of fill capacities to meet specific requirements and ensure maximum economy in installation. Each cylinder is manufactured from high strength alloysteel. The larger cylinders have an optional liquid level device for ease of contents monitoring and improved system maintenance.
NozzlesA range of custom-designed nozzles are available including 180° bulkhead and 360° deckhead types.
