Respondol® ATF C 3x3%
One fluorine-free concentrate at 3% for low, medium and high expansion foam – certified to EN 1568:2018 parts 1–4 and ICAO Level B, usable down to −8 °C.
Respondol® ATF C 3x3% is a superior-quality synthetic fluorine-free foam (F3 / SFFF) concentrate from Angus Fire for extinguishing and securing all types of flammable liquid fires and Class A incidents. It is used at 3% on both hydrocarbons and polar solvents. It holds certification to all four parts of EN 1568:2018 in fresh and sea water and ICAO Level B approval for aviation use, and it remains usable down to −8 °C with no loss of performance after freezing and thawing. Hexfire supplies Respondol® ATF C 3x3% across Central & Eastern Europe and supports your transition from first audit to commissioning.
At a glance
Why Respondol® ATF C 3x3%
Respondol® ATF C 3x3% combines the simplicity of a single 3% setting for all fuels with an unusually broad set of approvals. EN 1568 parts 1 to 4 cover medium and high expansion foam as well as low expansion foam on hydrocarbons and polar solvents, and ICAO Level B confirms its performance on aviation fuel fires.
Its lower freezing point makes it a good fit for vehicles and installations exposed to winter conditions: it can be used down to −8 °C and keeps its performance after freezing and thawing.
Like all Respondol® ATF versions, it forms a vapour-sealing foam blanket using a patented surfactant combination, without any PFAS. It is proportioned with conventional portable and fixed foam proportioners and applied with air-aspirating discharge devices.
How Respondol® ATF C 3x3% is used
Respondol® ATF C 3x3% is one of the few fluorine-free concentrates certified across the full EN 1568 range – low, medium and high expansion. One concentrate in stock can therefore feed handline branchpipes, medium-expansion branchpipes and high-expansion generators, always at the same 3% setting.
| Application | EN 1568 part | Typical equipment |
|---|---|---|
| Low expansion – burning hydrocarbon fuels (petrol, diesel, kerosene) | Part 3 | Foam branchpipes, monitors, foam pourers – e.g. HI-COMBAT™ LEX |
| Low expansion – polar solvents (alcohols, ketones, esters, ethers) | Part 4 | Foam branchpipes, monitors, foam pourers |
| Medium expansion – bund fires, spill fires, vapour suppression | Part 1 | Medium-expansion branchpipes and pourers – e.g. HI-COMBAT™ MEX, Semi-Fixed Bund Pourer |
| High expansion – total flooding of cellars, holds, warehouses and cable ducts | Part 2 | High-expansion foam generators – e.g. HI-COMBAT™ Mini Turbex, HI-COMBAT™ Turbex |
| Aviation fuel fires | ICAO Level B | Airport rescue and firefighting vehicles |
The concentrate is proportioned at 3% with conventional portable inductors – such as the HI-COMBAT™ Portable Foam Uniductors – or with fixed in-line proportioners, and it works with soft or hard, fresh, brackish or sea water.
Where Respondol® ATF C 3x3% is used
Municipal fire brigades – one 3% concentrate on the vehicle for road tanker accidents, fuel spills, warehouse fires and cellar flooding with high-expansion foam, including in winter.
Airports and aviation – ICAO Level B approved for aviation fuel fires on rescue and firefighting vehicles and in hangars.
Industry, storage and transport – tank farms, bunds and loading areas with oils, petrol, diesel, aviation kerosene, alcohols, ketones, esters and ethers.
Enclosed spaces and cable ducts – total flooding with high-expansion foam using foam generators.
Outdoor and unheated sites – usable down to −8 °C with no loss of performance after freezing and thawing.
Class A fires and spill control – wetting agent for wood, paper and tyres; vapour-suppressing foam blanket on unignited spills.
