Aquafighter Fuel Tank Water Absorber


Removes free, bound & emulsified water, for water-free fuel

When water enters the fuel tank, whether that's through condensation or ingress from a crack in the fill cap, the fuel can start to form diesel bug sludge. This sludge can block filters, pumps and injectors, cause loss of engine power, difficulty getting up to speed, expensive fuel system corrosion and poor fuel economy. All of these issues can result in expensive repairs and equipment not performing as it should. Can you take the risk of not dealing with diesel's biggest problem - water?

About the Aquafighter range

Aquafighter has a range of high-quality fuel tank water absorbers that remove both free, bound and emulsified water from fuel, keeping it water-free at all times.


  • Captures and removes free & emulsified water inside the tank.
  • Models for yachts, plant machinery, genset belly tanks and larger storage tanks.
  • Prevents diesel bug from forming.
  • Reduces filter replacement by around 60%.
  • Eliminates the need for most additives.
  • Reduces water levels down to 75ppm.
  • Suitable for diesel, kerosene and biofuel.


CTS is the UK agent for Aquafighter, meaning we can offer our Middle Eastern customers competitive pricing and technical support whenever needed.   

A COMPLETE solution to water in fuel

Unlike other absorbers on the market which only remove the free water, Aquafighter is able to remove all types:


Free water in diesel fuel is visible as a layer of separated water in the fuel tank that has sunk to the bottom, creating a visible layer of water under the fuel. This is where diesel bugs often grows.


Suspended water (sometimes known as bound water) is where the water has bound to the fuel molecules making it appear cloudy. As the diesel becomes full of suspended water, it drops to the bottom of the tank and becomes free water.


Emulsified water is where water becomes completely emulsified turning the diesel milky in appearance. This can happen when fuel passes through pumps and filters, under pressure changes, agitation, and heavy cavitation.
