What is Microbial Contamination?

There are at least 27 separate species of microbes - bacteria, yeast and fungus that can exist in and feed on crude oil (and it's products).
These oil eating micro-organisms have a natural affinity with petroleum based products because they actually produced crude oil by decomposing billions of tons of ancient forests and animals. Subsequently when crude oil is extracted from the ground it has a resident microbial population - fortunately this is killed off during the refining process.
However, just as they did millions of years ago, oil eating microbes exist abundantly in our environment today.  Their spores travel freely in the air and water and readily re-enter petroleum products at any point in the petroleum supply chain and your fuel tanks - through breather caps and filler ports.
Then with the right conditions - a temperature range between 15o and 44oC and a little free standing water and a single cell weighing virtually nothing can rapidly grow, divide in two and so on, to become a slimy biomass weighing 10 kilograms (22 pounds) in 24 hours - It does happen!

What are the effects of Microbial Contamination?

Dependant on the species present - microbes either form matting, slime, sludge, organic acids and sulphides. In combination/ consortium oil bugs are extremely corrosive with the ability to degrade any metal and many types of rubber.

The matting, slime and sludge they create in abundance enters the fuel lines to block filters, injectors and in severe cases, the fuel lines themselves. The slime, visible on tank walls and fuel system components, is a protective layer that effectively shields against poisonous chemicals ~ biocides/ can be called additives.

The organic acids degrade protective coatings such as paints, rubber, some plastics and metal oxide films as well as destroy or inactivate chemical corrosion inhibitors and cause hydrogen embrittlement of metals. Black deposits on copper or copper containing alloys in pipe work and bearings as well as pitting are evidence of microbial induced corrosion.

Engines rely on high quality fuel that has been properly filtered and separated (from water), with no flow restrictions, to achieve proper atomization, combustion, engine performance and fuel efficiency. Fuel that is infected with bacteria is not reliable and there are many and varied consequences of using contaminated fuel.

These include:

1. encouraging growth of further contamination 
2. fuel filter clogging and blockage
3. coalesce malfunctions
4. engine wear due to variations in fuel flow
5. corrosion of the fuel system
6. corrosion of engine fuel injectors
7. damage to in-line instruments

Engine fuel injection equipment and fuel pumps are most susceptible to the effects of microbial contamination resulting in corrosive damage

Ultimately, performance suffers and fuel consumption and maintenance costs increase, but perhaps the most critical concern is the real potential for blockages in the fuel system which cause engine failure while underway - with potentially devastating consequences.

How do De-Bug Clean Fuel Units work?

De-Bug Units are static magnetic inline device that create an optimum magnetic flux field directly responsible for destruction of the cell membrane. Exposing the microbes to a strong, changing magnetic field will ensure maximum destruction of the cells. The debris stays randomly suspended in the fuel and due to their sub-micron size easily pass through engine components and burned with the fuel.


Other systems use a single magnet and claim similar success. What makes De-Bug Units using a three magnet stack better?

De-Bug Units are One of a Kind. When the inventors in knowing how good this system is, patented the De-Bug system worldwide. Single magnet systems are sub-par of the De-Bug System

Why De-Bug Tri Mag & Multi Mag compared to single magnet units. In the development stage the inventors of De-Bug Units used single magnets Units and found them to be partially effective.
That could be Ok, as there was nothing better on offer in the market, however after further testing using different combinations of magnets, gauss strengths and configurations they concluded the triple & multi magnet systems were substantially better for eliminating microbial contamination than the single magnets.
A risky decision had to be made; to produce the single magnet system that was cheaper & easier to manufacture or to develop the triple & multi magnet systems that worked incredibly well but would require far more design work, a greater manufacturing process and large capital investment.
After consistently achieving excellent results from field testing the inventors chose the triple & multi mag systems and patented them as De-Bug -Tri-Mag & Multi-Mag. 
Twenty years on, De-Bug Units have achieved fantastic results, have been further proven in ICI Laboratories, by Shell New Zealand, The Singapore Port Authority, The Dutch Fishing Fleet and University of Wellington. No single magnet Unit has proven these results.
De-Bug Units have proven themselves ten of thousands of time and proof is they authentically endorsed by significant number of end users that had a persistent bug problem, then by fitting a De-Bug Unit; the bug problem solved permanently!

Further more De-Bug Units have a bowl, these catch inorganic materials and some water before they reach the filters, further helping fuel filters last normal service intervals - it's a lot easier and cost effective to clean a bowl than to be constantly changing filters.

Are De-Bug Units a Filter?

No. The De-Bug Units are not a filter, they are a treatment Unit that requires no chemicals, replaceable items or wires. 

How cost effective is it?

De-Bug is a cost effective, one time, permanent installation, with no moving parts, no electrical hook-up, and maintenance that may require only an occasional cleaning. And unlike chemical biocides, micro-organisms which have been destroyed by the De-Bug unit do not collect at the bottom of fuel tanks. Instead, the debris stays randomly suspended in the fuel and due to their sub-micron size easily pass through engine components. They are then burned with the fuel, there is no build-up of microbial sludge in tanks. Consider that if you have to clean your fuel tanks once, you will most likely pay more than installing a De-Bug.


What about pressure drop?

Through careful design, De-Bug units show no pressure drop across the recommended unit for specified flow rate.

Will the fitting of a De-Bug unit save on fuel costs?

In Independent tests conducted by major Companies prove
De-Bug Units reduce fuel consumption.

Will the fitting of a De-Bug unit reduce engine smoke emissions?

Yes, by removing microbial contamination combustion improves - reducing engine smoke emissions.

What is the maximum temperature in which a De-Bug unit will operate?

A.      Rubber 'O' Ring - maximum 107 degrees Celsius.
B.      PVC internal washers - maximum 80 degrees Celsius.
C.      Magnet Spacers - maximum 170 degrees Celsius.
D.      Ceramic magnets will tolerate up to 100 degrees Celsius.

We do not recommend our units to be used in any situation where fluid is heated beyond the maximum tolerance level of the PVC internal washers. To protect the integrity of the De-Bug unit, fluid temperature at 10% below the maximum tolerance level would be a safe figure to use.  Say 70 degrees Celsius maximum temperature.


Why use Biocides?

Biocides are frequently used to treat severe contamination, however nearly all, if not all are hazardous chemicals that require at least careful handling. Although some are marketed as being "environmentally friendly", but in my opinion I can't understand how that can be.

Biocides kill living cells, which happen make up just about everything in our environment. For instance we are made of living cells and inconsequence biocides require careful handling - avoid breathing in the fumes they emit, avoid contact with the skin and then there's issues of the changes they create in the exhaust emissions and what happens to bugs they kill - which are full of poison.

Adding biocides to the fuel system may kill many of the microbes but this creates another problem - The dead cells collect on the bottom of the fuel tank and forms sludge. Nasty stuff - this sludge is  toxic because of the toxicity of the biocides used requiring removal to EPA standards. This thick inert sludge is sucked up into the fuel system to block fuel filters - causing reduced power and eventual damage to the fuel pump.

Alternatively there is no build up of bug sludge in the tanks when De-Bug Clean Fuel Units are used - De-Bug Clean Fuel Units eliminate microbes by an aggressive process that tears them to a sub-micron size which easily passes through fuel filters and injectors to be burnt with the fuel.

It is commonly found that microbes develop immunity to biocides. Many uses of biocides report bio-mass growth in systems despite regular treatments with biocides. So if you have a fuel bug problem you can expect to be constantly buying and using biocides - And in consequence to be need to clean your tanks a number of times over a twenty year period.

De-Bug Clean Fuel Units last 20+ years. It is worth noting you'll pay more to have the tanks cleaned once than what a De-Bug costs - By fitting a De-Bug Unit you do away with repeatedly buying and handling poisons, and you won't have to deal with bug sludge or change blocked filters.

By fitting a De-Bug Clean Fuel Unit, your engine/s are fed clean unadulterated fuel - your engine/s will maintain the best performance they can deliver and  maintenance expenses will be reduced, as will fuel burn and pollution. Further there is no repetitive cost of ownership - nothing to replace, no wires, no additives - just fit to the fuel line,  and the job is done while you run the engine/s.

What is the Kill Rate?

The patented design of multiple ceramic permanent magnets located within the unit, when properly sized and strategically placed, have been shown in a tests conducted by Shell New Zealand to have a 97.5% efficiency in destroying the damaging micro-organisms within a single pass.

Are there microbial bugs in lubrication oil?

Oil has bacteria therefore the answer is Yes. This extends to palm oil, coconut oil, fish oil, Emu oil, etc.  If you encounter evidence of contamination, you can be reasonably sure that it is contamination. 


Where in the fuel line should I install my De-Bug unit?

The De-Bug Fuel Treatment Unit should be mounted as close as possible to the main fuel supply source (fuel tank) and in the fuel line after any strainer or water separator but before the primary filter. Full installation instructions are included with each unit.
