Firetec CTX Multi Nozzle

CT automatic fire extinguisher systems are unmatched for the effective suppression of single point of outbreak fires in mild conditions. However, where multiple outbreaks can occur simultaneously, or in conditions of high turbulence, (such as outside, or in the engine compartment of a large vehicle with a large cooling fan), where the direction of heat incident on the Reacton™ tubing can be distorted, the more advanced Firetec® CTX systems have been designed.

Our invention of the CTX systems in 1998, was made possible with the introduction of our own range of patented automatic Firetec®-Tsunami pressure differential valves. We named these valves ‘Tsunami’ in 1997 to indicate the powerful discharge of fluids produced. These systems combine the highly effective, totally non-electrical simplicity of the Firetec® CT systems, with those advantages previously claimed for multi nozzle automatic fire fighting systems.

CTX systems make use of the same Firetec® Reacton™ tubing to act as both detector and accurate discharge unit. However in CTX systems, the instant drop in pressure within the Reacton™ tubing during activation, is used to trigger a separate and simultaneous discharge of suppressant via the Tsunami-valve and (other than for CTX 9 versions) array pf pre-positioned nozzles. The protection provided is thus not only two-fold, it ensures that nozzles can be positioned to protect specific items regardless of turbulence.

Although the action of the primary Reacton™ discharge itself may suppress the fire, the activation of the Tsunami-CTX valve gives rise to a number of unique options. For instance this valve can deliver a different suppressant via the nozzles than that delivered by the Reacton™ tubing, and it can be at a completely different pressure. The separate quantities of suppressant delivered by the Reacton™ tubing and the nozzles, are both chosen by the customer. Thus the Firetec® CTX system allows users to specify separate suppressants, at different pressures and in different quantities, in one dual system.

As an example, a Firetec® CTX system can be used to protect a large and complex vehicle with a manned compartment (cab), and a large unmanned engine compartment. The cylinder(s) are mounted wherever practical. The Reacton™ tube(s) are routed within both the manned and unmanned compartments, whilst the nozzle supply pipe and nozzles themselves are placed only within the engine compartment.

Fire detected at any point along the Reacton™ route gives rise to a discharge response at that point, whether in the manned or unmanned areas. In this example, the Reacton™ tube would be set to deliver water spray or a moderate expansion foam which is not harmful to the operator, should the fire have initiated and ruptured the Reacton™ line within the cab.

Regardless of the point of initiation, the slave function of the Tsunami-CTX valve, ensures that the valuable engine compartment is simultaneously and independently protected by the second chosen appropriate medium, e.g. low micron water mist, foam, CO2 or designer gas, etc.

The Tsunami CTX-valve gives the user the option to protect equipment regardless of turbulence, by considered positioning of delivery nozzles. Depending on the actual format of the Tsunami employed, reliable protection can be alternatively provided to specific and/or remote components and/or whole compartments.

Firetec® CTX Options

• Format I (CTX No. 7 Tsunami-valves) use the same suppressant at the same pressure in both the Reacton™ line and the cylinder. Discharge is jointly via Reacton™ route and nozzles. This can be used to protect engine compartments in large machines with large cooling fans.
   
• Format II (CTX No. 7b Tsunami valves) is similar to Format I except 99% of the discharge is routed via the nozzles. This is useful where it is important that the area of discharge is confined to that covered by the nozzles.
   
• Format III (CTX No. 8 Tsunami valves) uses suppressant at a higher pressure in the cylinder, which can also be a different suppressant. Discharge is by both Reacton™ route and nozzles. This allows for the storage and release of high pressure suppressants (e.g. CO2) via the nozzles, under the control of safe low pressure in the Reacton™ tube. This option can also be used for whole room flooding.
   
• Format IV (CTX No. 9 Tsunami valves), as with Format III uses a suppressant at a higher pressure in the cylinder than in the Reacton™ tube. However here the suppressant stored under high pressure in the cylinder, is released at a reduced pressure, entirely via the Reacton™ tube. This format has no nozzles. This is useful for the detection and fighting of fire in a confined space such as within a wiring loom or cable conduit. The suppressant from the cylinder can also be released slowly to counteract continuous arcing.

Firetec® CTX Sales

Firetec® CTX systems are sold by authorised Firetec® dealers, or directly from Fire Monitoring Systems Ltd. Price is very competitive compared with traditional hit-or-miss, multi nozzle, electrically initiated systems, and is based on the complexity of the installation involved.

Customers are strongly urged to discuss their particular requirements directly with our technical staff to ensure that the appropriate system/option is supplied.

For prices and to find your nearest Firetec® dealer, contact us.

Firetec® CTX Installation

• Installation of Firetec® CTX systems must be carried out by an authorised Firetec® dealer, or a suitably trained individual registered with Fire Monitoring Systems Ltd.
   
• Some special tools and equipment is required.
   
• Full safety and installation instructions are supplied with every CTX system.

Firetec® CTX Service

• With most CTX installations, periodic servicing is confined to checking the pressure gauge, the nozzles to ensure that the dirt seals have not become dislodged, and the general pipe work for signs of external damage.
   
• Where the customer has specified a powder filled CTX system for use in an environment of strong vibration, further periodic servicing is necessary.
