Tanklux is a family owned and managed business established in 1966 and is run by the 2nd generation of the Bollaert family. With 13 employees from the Grand Duchy and the region, Tanklux offers storage and transshipment services for petroleum products in the port of Mertert. In the course of converting fire fighting systems to fluorine-free foam agents, we use our expertise and provide our customers with the best possible support.
The Maxi Terminal Hamm covers an area of around ten hectares and is a container terminal of the latest generation. Up to 52,000 loading units can be moved at the Hamm site every year. The special design of the handling crane also enables the loading of large tank containers (up to 75 tons). This makes the Maxi Terminal the only public and [...]
In an airport emergency every second counts. That's why airports count on the best equipment available. Fire engines which meet ICAO standard achieve high acceleration values rates and carry tons of fire extinguishing agent. The fire extinguishing foam used must also meet special performance criteria on kerosene and aviation fuel. With vaPUREx® LV ICAO C 3%, Dr Sthamer is setting new standards
Wald- und Vegetationsbrände treten immer häufiger und intensiver auf. Sie stellen ein großes Risiko für Menschen und Tiere, aber auch für den Wald als Wirtschaftsfaktor und insbesondere als Speicher für CO2 dar.

Daher ist es von entscheidender […]
In many fire situations—especially vegetation and wildfires—the availability of extinguishing water presents a logistical challenge. This makes it all the more important to use available resources as efficiently as possible. One effective method for optimizing water consumption is the use of wetting agents. What are wetting agents? Wetting agents, such as the high-performance wetting agent "UltraWet®" from Dr. STHAMER, are special additives that […]
Viscosity is a measure of the thickness or internal friction of a liquid. It describes how much a liquid resists deformation or flow. Simply put: the higher the viscosity, the “thicker” the liquid – and the lower the viscosity, the more “fluid” or “runny” it is. Most fluorine-free foam extinguishing agents are low-viscose, meaning they have a thin, water-like consistency and can be easily proportioned. […]
An unusual action is causing a stir in North Rhine-Westphalia: In the forests of Affeln in the Sauerland region, a flame retardant in a striking pink color was sprayed on approximately 200 square meters of forest floor. This measure has a serious background and is not the only such project.
Forest and vegetation fires are becoming increasingly frequent and intense. They pose a major risk to humans and animals, but also to forests as an economic factor and, in particular, as storage sites for CO2.
The transition to fluorine-free foam extinguishing agents raises many questions, particularly among users. In addition to concerns about extinguishing performance, users are eager to know whether the existing extinguishing equipment and established firefighting tactics can continue to be used.
For testing the induction rate with the respective proportioning system, we have prepared a Technical Information (in English), which can serve as a test recommendation and assistance.
vaPUREx® LV ICAO are foam agents that are 100% biodegradable. When foamed, the agents can be used for direct foam application on aviation fuels. Other fuels and oils used at airports can also be extinguished with vaPUREx® foam agents. The advanced formulations from new raw material combinations reduce the loading of the foam with fuel at […]
No renewal of approval according to FM-5130 for STHAMEX-AFFF FXS AS 1% F-0 #2147, MOUSSOL FXS LV AS 1/1 F0 #2149; STHAMEX-AFFF FXS AS 3% F-0 #2354, and MOUSSOL FXS LV AS 3/3 F-0 #2356. The American property insurer Federal Mutual (FM) has changed the requirements of the test standard FM-5130 for foam extinguishing agents to comply with the current legislation regarding fluororganic compounds, […]
The topic of 'fluorine-free', or the presence or absence of organic fluorine compounds in foam agents, is currently a hot topic. It's the subject of various discussions, regulations, and a cause of significant uncertainty among users. To contribute to the clarification of the term 'fluorine-free', we have developed a technical information sheet.
