De-Bug Clean Fuel Units

Marine Endorsements

Condor 10:

“Once the De-Bug Units were installed we did not have any more problems with fuel contamination caused by micro-organisms and can therefore confirm that your company’s units worked successfully.” – Read Report

Ray Piper:

“I have had my boat for five years, and I’ve always had clogging fuel filters, excessive black smoke coupled with sluggish uneven running and power loss. Because the filters were always packed and filthy, I was forced to change them after running through about 300 gallons of fuel.” – Read Report

Semo Marine:

“Ssangyong Nigata 16V 16FX 1,950 Kw x 2 and Ssangyong Cummins 150 Kw x 2 – Average fuel consumption reduced by 8%, Average Exhaust Temp reduced by 6%, Filter change reduced 66%. Prior to fitting De-Bug Units injector nozzles had to be changed every 3 months after fitting De-Bug Units, the injector nozzles did not require changing for 9 months.” – Read Report

Ship Control Services: L4000

Pielstick 12 PC 2.2V – Prior to installing a L4000 De-Bug Unit – Vessel’s shaft RPM was noted at around 190, main engine exhaust temp” 

A merchant vessel operated by Ship Control Services (PTE) Ltd. of Singapore, had engine exhaust temperatures above the maximum recommended levels.
An L4000 De-Bug unit was fitted which resulted in a reduction of the engine exhaust temperature to within limits. In addition, daily fuel oil consumption (for the same shaft revolutions) was reduced from 17.4 metric tonnes to 15.5 metric tonnes – Read Report

Ship Control Services: L1000

“Genset fuel nozzle “trumpeting” and poor combustion (load fluctuation), after fitting De-Bug (L1000) no more problems.”  –  Read Report 

Singapore Naval Maintenance Base:

“Undertook a trial on three vessels involving the monitoring of fuel consumption (usage per hour).

The two vessels that were known to have higher than normal fuel consumption recorded savings of 20%, and the third vessel, which had normal fuel consumption, returned savings of 15%”      

Singapore Port Authority:

“This is to inform you that the port engine that is fitted with you De-Bug L1000 Unit has lesser frequency of filter change than the starboard engine … about 40%”     

Undertook a trial in one of its vessels and fitted a L1000 De-Bug unit on one of the vessels engines. After fitting, the number of filter changes reduced by 40% compared with the other engine. The other engine was subsequently fitted with a De-Bug unit.

High Speed Catamarans

Operating between Singapore and Malaysia frequently experienced main engine and auxiliary engine stoppages due to heavily clogged water separators and secondary fuel filters resulting from a jelly like growth and the filters had to be replaced every three days.
The operator tried using fuel additives but found the cost prohibitive. In addition to the blocked filters, the operator experienced expensive damage to the fuel pumps and injectors.

Since installing a De-Bug unit, fuel oil filter elements did not have to be changed within the first three months of operation, no further damage was reported and fuel economy was improved – Read Report

Union Rotorua:

‘On fitting the De-Bug L4000 magnetic devices, it was immediately noticeable that fuel filter life was extended and the frequent filter changes were no longer required’ 

A merchant vessel operated by Union Shipping of New Zealand, was supplied with over 1000 Tonnes of light marine diesel bunker oil which was found later to be contaminated with Hormonicus Resinae. The bacteria caused severe problems by fouling fuel filters; filter life was reduced from 6-8 weeks to 17 hours.

On fitting two De-Bug L4000 units, the fuel filter life was extended such that frequent and expensive filter changes were no longer required. The two units successfully coped with fuel flow rates of 78 tonnes of fuel every 24 hours. While cleaning of the infected bunkers was still required, the fitting of the De-Bug units allowed this to be scheduled for a convenient time, allowing the vessel to continue a normal trading pattern and generating revenue for it owners. No further problems were reported during the last five years of service that were completed in 1998  – Read Report

Dolphin Wild - Island Cruisers:​

Experienced microbial spoilage in the diesel fuel header tank, and during bad weather, a build-up of sludge-type biomass in the fuel feed line to the purifier halving its capacity from 1 tonne per hour to 0.5 tonnes per hour. In addition, the fuel strainers on the feed lines to the twin 3,000 HP engines had to be cleaned every ten days to prevent fuel starvation.
After fitting an L4000 De-Bug Unit, restrictions were eliminated, and the cleaning cycle for the engine strainers was increased to ten weeks, a sevenfold increase in life – Read Report

Tropic Star Lodge 1st Report:

Our engines are running cleaner with less downtime for our clients and we have reduced our replacement of fuel filters by more than half. We are also experiencing a reduction in our fuel consumption’ – Read Report

Tropic Star Lodge Follow-up Report:

‘After using for 2 years “…have been using De-Bug Units for over two years on our extensive fleet of yachts, generators, trucks and other vehicles” ” … with the use of De-Bugs, we have increased our engine time between overhauls from 3000 to 4500 hrs with very little mechanical downtime… – Read Report

Deep Submergence:

Rescue Vehicle Support Ship (DSESS) Kellie Chouest, leased to the US Navy for research, rescue and retrieval, suffered severe algae contamination and the fuel filters required replacement every few hours. Installation of De-Bug units in the fuel supply lines solved the problem and allowed filter replacement to be undertaken at the normal servicing intervals.   

Ray Piper Followup Report:

“From the first trip, I noticed a better engine performance. For the first time in my memory, the engines were pulling evenly. They were running cleaner and quieter. There is no smoke at all. Before I had thick black smoke. The engines are really sweet now, and the fuel is crystal clear. Numerous people have commented on my clear fuel. The De-Bug has been on my motors for a year now and I haven t had to change the filter once.

I also have figures to prove that I have greater fuel economy” – Read Report

Two Koren trawlers transiting to Oregan USA:

Participated in a comparative trial from December 1995 to June 1996; Trawlers #601 and #608, both were considered identical, except #608 had a De-Bug unit. fitted. The two trawlers left Korea the same day to operate off the coast of Portland, Oregon, USA. Against the background of similar operating hours and total loading on the engines, the trial demonstrated:
1. Fuel saving of nearly 20%
2. Nozzle life per running engine increased on average by 25%

Inconnu off Channel Islands:

60′ Vessel for crab and lobster fishing off the Channel Islands experienced fuel starvation due to filter blockage. The problem became so severe that the filters were being replaced every day. Treating the fuel with Biocide only increased filter life to two days! Upon fitting a De-Bug unit, the contamination problem was eradicated and filter life increased to 40 days. The owner also dispensed with using expensive chemicals.

Norna - Scottish Fisheries Protection Vessel

“Results are nothing short of amazing: Within 2 weeks no evidence of bug slime on either of our filters. Now fuel filters only get changed when we do a service and they still look okay even then.”

Shell Deepwater Production USA:

“We are pleased to inform you that since we installed one of your L-4000 De-Bug units here on Auger, the results has been better than expected …”

Four gas turbines used for power generation on an oil rig. These turbines burn 5 gallons per minute per engine when loaded. When a De-Bug Unit was fitted: “… filter usage cost has dropped from $8,000 per year to less than $1,000 per year. We are satisfied with the appearance of the fuel we have has no unscheduled engine shutdowns due to clogged filters. The De-Bug Unit has performed as well as we were told it would …” – Read Report
