WETTING AGENT FireEx

By « Fire-Ex 2000 » we mean the safest, most efficient and functional system for wet water production on the market. For years, it has become synonymous with the uncomplicated, simple and inexpensive solution that fire brigades worldwide trust. It has already been replicated several times but never surpassed in its essential features!

All good solutions are essentially straightforward and that is also the case with Fire-Ex 2000. A cartridge containing concentrated wetting agent is inserted into a sieve support which is flushed with extinguishing water in a pipe. The cartridge slowly releases its active ingredients into the extinguishing water, which enhances its physical properties (extinguishing, cooling, adhering, penetration, etc.).

Our TKW exclusive additive « Fire-Ex 2000 » is a solid cartridge, which, in addition to a simple water-relaxing effect, also contains dedicated grease and oil-dissolving active ingredients. We have increased the extinguishing effect by producing an emulsion which has a significantly lower surface tension and at the same time a higher adhesive effect on Class A fire material (wood, walls, etc.) and can therefore develop the highest possible extinguishing effect. The wetting water thus penetrates faster and deeper into the burning material than before and also adheres longer and better to surfaces, which cools and protects them.

The reduction in extinguishing water is up to 50%, which means that a faster extinguishing success can be expected with lower fire load emissions and lower consequential costs. Due to the significantly longer adhesion time, both better cooling and covering of not yet affected fire material (prevention) takes place. In the case of loose fire material such as pressed, stacked or poured material, penetration is much deeper and faster and the retention time at the source of the fire is much longer.

Our system is absolutely independent of flow rate or inlet pressure! The fire brigade can use a BM-jet pipe as well as a DM-jet pipe, in any case our wetting agent tank will certainly be able to carry out a much more effective, faster and water-saving extinguishing attack than with pure water. Nor are high pressure losses caused by flow restrictions or reduction of throwing distance. The previously used jet pipes and fittings can continue to be used without problems, making the TKW Fire-Ex 2000 both simple and future-proof.

This agent can be used in the environment without any risk, Fire-Ex 2000 is free of fluorine, PFOA and similar PBT substances (persistent, bioaccumulating and toxic), i.e. it has no accumulating effect in the soil or in living organisms and therefore does not contaminate soil or fire loads in any way!

The cartridge itself can be safely disposed of in normal household waste! This means for the fire brigade an absolutely fluorine or PFC/PFOS free extinguishing but with the maximum possible extinguishing effect of a tested and proven additive. We can present a safety data sheet as well as an environmental certificate for our Fire-Ex 2000, in which a 100% biodegradability as well as the lowest possible water hazard class « 1 » is declared. Furthermore, our system is currently unmatched in terms of maximum runtime/water quantity. It is also the system with the lowest pressure loss rates on the market! The larger « mixing valve » with a maximum flow rate of 950 l/min is now frequently installed by vehicle manufacturers in small and medium-sized vehicles and is firmly piped with the quick attack, so it is already established in vehicle construction.

It convinces with its high performance flow rate of more than 500 l/min, a producible volume of more than 3000 l wet water as well as an unparalleled connectivity and compatibility. It is fitted in the Storz C hose line or in front of a distributor C/DCD and contains a cartridge with a concentrated wetting agent mixture, which is flushed with water and whose active ingredients are slowly released into the extinguishing water. All fittings of multi-purpose branch pipes DM, CM and BM can be used as well as hollow jet pipes or mist jet pipes with a flow rate of up to 500 l/min.

  • Quick and easy installation in seconds

  • Can be used on any vehicle with or without tank and portable pumps

  • Working range pressure from 0-16 bar

  • Saves up to 50% extinguishing water

  • Free choice of installation point: after the pump, before the distributor or in the hose line to the jet pipe

  • Simple operation: self-explanatory color coding for the couplings (blue – from the pump, red – to the fire)

  • Cartridge can be changed in seconds by coupling the adapter B/C

  • Adapter secured against loss with chain

TKW FireEx 3500 B

The wetting agent tank TKW Fire-Ex 3500 B is designed to produce wetting agent for firefighting and is a particularly powerful fitting. Due to its even larger DN80 diameter, the wetting agent tank TKW Fire-Ex 3500 enables operation both in front of and in type B hose lines as well as during cannon or monitor deployment. With a very low pressure drop of less than one bar at 1,000 l/min, the wetting agent tank does not limit the flow rate but rather enables very high flow rates and long distances. Like the Fire-Ex 3000 C, the Fire-Ex 3500 B is fitted in the hose line and contains a cartridge made of a concentrated wetting agent mixture which is flushed with water and whose active ingredients are slowly released into the extinguishing water. All fittings of multi-purpose branch pipes DM, CM and BM can be used as well as hollow jet pipes with a flow rate of up to 500 l/min.

TKW mixing valve FireEx

The gold standard in wet water production! Safe wetting agent production in one step, safe and easy to use, continuous water supply even during reloading, very easy and self-explanatory to operate without the possibility of operating errors, and with a flow rate of 0l/min up to 950 l/min.

The fitting with Storz C-52 (Fire-Ex 3000 C) or B-75 (Fire-Ex 3500 B) on both sides can be permanently installed in the vehicle or can get set up at the deployment site. The solid and durable frame ensures safe footing and the design of the fitting makes it easy and comfortable to refill in any position! The special feature of the mixing valve compared to the wetting agent tank is the unique ability to dispense both pure water and wetting agent. The machine operator can change the operating mode from « wetting water » to « water » at lightning speed with a lever, e.g. to reload a new wetting agent cartridge.

  • Ready for immediate operation with cartridge already inserted

  • High flow rate of up to 950 l/min

  • Uninterrupted operation even when changing cartridges

  • High-quality materials for long-term, trouble-free performance

  • Can be used both permanently installed and portable, e.g. for rapid extinguishing, pump outlet or after a portable pump

  • Produces up to 3000l wet water for fire class A, decontamination or oil and grease cleaning

  • Can be quickly switched to water operation, reloaded and reset to wetting agent operation

  • Even after the cartridge has been used up, the extinguishing process can continue with water without interruption

Analytical report on the environmental impact of FIRE-EX 2000

According to the results of the test, presented by alcum GmbH, Analytical Laboratory for Chemical and Microbiological Testing, the water hazard class of FIRE-EX2000 was determined in October 1995. The determination of the water hazard class or the individual water hazard figures was carried out in accordance with « LTwS-No.10, evaluation of substances hazardous to water » (published by the Federal Environmental Agency). The following biological tests were carried out with the FIRE-EX2000 solid cartridge:

  • Fish toxicity (DIN38412L31)

  • Daphnia toxicity (DIN38412L30)

  • Algae, growth inhibition test (DIN38412L9)

  • Pseudonomas, cell proliferation inhibition test (DIN38412L8)

  • Biological degradability (according to DIN38412 part 21) The overall result of the above-mentioned environmental impact studies is as follows: With an arithmetically determined water hazard classification of 4.8, the sample itself falls into water hazard class 2. However, since there is excellent biodegradability, no impairment of plant sustainability and no abnormality in the earthworm preference test, the wetting agent is classified in water hazard class 1 by means of bonus allocation. Thus, if 200mg/l are added according to the « LTwS-No.10- evaluation of substances hazardous to water », the wetting agent is only « slightly hazardous to water ».
