About us
Clean, reliable fuel is essential for protecting diesel engines, fuel systems and expensive equipment. Water, dirt, rust, dust, condensation and other contaminants can enter a fuel tank, where they can accumulate over time and eventually make their way towards pumps, filters, injectors and engines.
At DQTube, we supply DQTube In-Tank Fuel Filters nationwide from our base in Galway, providing a practical in-tank solution for businesses and operators looking to improve fuel quality and reduce the risks associated with contaminated diesel.
DQTube is designed to work inside the fuel tank, rather than simply filtering fuel after contamination has already travelled into the fuel system. The technology is designed to capture water and particulate contamination directly within the tank, providing an additional layer of protection before contaminated fuel reaches critical engine components.
We supply DQTube solutions for a broad range of applications, including trucks, tractors, construction equipment, generators, boats, agricultural machinery, diesel storage tanks, home heating oil, kerosene & HVO.
What Is a DQTube In-Tank Fuel Filter?
A DQTube In-Tank Fuel Filter is an in-tank diesel filtration product designed to remain inside the fuel tank during normal operation. Instead of relying exclusively on conventional filters positioned in the fuel line, DQTube addresses contamination at its source within the tank.
The system is designed to capture water and fuel contaminants, including dirt, rust, dust and other particles. Product information indicates that DQTube can capture large particles as well as very fine particles, including particles smaller than 10 microns, depending on the specific product.
This makes DQTube particularly useful for diesel operators who want to take a preventative approach to fuel contamination.
The principle is straightforward: the DQTube is placed inside the fuel tank, where it can interact with contaminants accumulating within the fuel. Water and other contamination can then be captured before they have an opportunity to travel further through the fuel system.
Why Is Water in Fuel a Problem?
Water contamination is one of the most important issues to consider when managing fuel, particularly diesel and oil.
Water can enter a fuel tank through several routes, including condensation, leaks, contaminated fuel deliveries, damaged seals and environmental exposure. Once water is present inside a tank, it can settle towards the bottom because water is denser than diesel.
This creates a potential problem because the water can eventually be drawn into the fuel system.
Diesel fuel contamination involving water can contribute to issues including:
-
Fuel system contamination
-
Injector problems
-
Fuel filter blockage
-
Corrosion
-
Microbial growth
-
Fuel degradation
-
Reduced engine reliability
-
Unplanned downtime
-
Increased maintenance requirements
How Does DQTube Work?
The concept behind DQTube is relatively simple.
The appropriate DQTube product is placed inside the fuel tank, where it remains during operation. The product is designed to interact with water and contaminants within the tank, capturing contamination before it can continue through the fuel system.
Some DQTube products are specifically designed to remain inside tanks continuously, while other configurations can be used for particular fuel-treatment or storage applications. Product specifications vary according to the model.
For example, published specifications for DQTube Standard give dimensions of approximately 4.5 cm in diameter and 30 cm in length, with a stated water-capture capacity of 400 ml.
Other DQTube storage products are available in substantially larger configurations for larger tanks.
The correct product should therefore be selected according to the application rather than simply choosing a product based on physical size.
Can DQTube Replace a Conventional Fuel Filter?
DQTube should be viewed as an in-tank fuel contamination management solution, rather than automatically as a replacement for every conventional fuel filter.
Traditional fuel filtration remains an important part of many diesel fuel systems. Conventional filters positioned between the fuel tank and engine can remove contaminants from fuel as it passes through the fuel system.
DQTube takes a different approach by addressing contamination inside the tank itself.
The two approaches can therefore complement one another. DQTube can help reduce the amount of water and particulate contamination progressing from the tank, while conventional fuel filtration provides additional filtration before fuel reaches sensitive engine components.
This layered approach can be particularly useful for demanding commercial, agricultural, construction and industrial applications.
