FAQ's General :


1) Does engine heat break down oil?

Oil is designed to withstand normal engine heat. The primary culprit in the degradation of oil are contaminants generated from the combustion process. Engine heat will only degrade oil when the engine is operating outside it's normal parameters.

2) What kinds of fluids can be filtered?
The Cleantechnics International filtration system can be used with lube oil, synthetic oil, hydraulic oil and bio-diesel fuel..

3) How is corrosion created?
If the water in the oil is not removed and mixes with oxygen, the result is corrosion.

4) How does water get into the oil?
Engine oil in the circulation has a much higher oil sump temperature than the outside air. When the oil is cooling down this creates a little under pressure which sucks air - which always contains humidity - into the engine through small gaps. These gaps e.g. are the oil dip rod or the oil inlet cover. This air precipitates at the ceiling and condensates. After the oil goes back to the circulation it carries water.

5) What is meant by Blow-by-effect?
The gap between the piston and sleeve provides for lubrication. Gas and particulate contaminants created in the combustion chamber "blow by" through this gap entering the crank shaft and thus enter into the oil circulation. The greater the gap the more blow by. Particulate contamination in the oil acts like sandpaper between the piston and sleeve causing scoring. Scoring increases the gap thus allowing for greater "blow by" which in turn introduces additional contaminants into the oil system. This cumulative cycle will eventually lead to significant scoring and a loss in compression causing the engine to work harder. A harder working engine results in a loss in fuel efficiency.

6) How does the Cleantechnics International system assist the crank shaft?
Through the virtual elimination of contaminants the Cleantechnics International system breaks the "blow by" cycle allowing engine compression to be maintained at peak operating efficiency.

7) How do damages at the cylinder occur?
The lubrication slit in the camshaft and in the piston is 15 mµ, at the crankshaft 20 mµ. Particles smaller than 35mµ are pressed through with a pressure up to 5 bar and if the oil is still cold particles are hard and create marks by its friction thus enlarging the slit and decreasing the compression.

8) Why after a filter change does additional oil have to be added?
Our filters have the possibility to hold up to 8 quarts of water. This additional storage room has to be filled initially with oil after the oil change.

9) What is meant by abrasive vs. adhesive parts?
Abrasive parts: firm parts created from marks.
Adhesive parts: surface friction caused by thermal overheat.

10) Does the installation influence the oil pressure?
There is no significant impact on the oil pressure.

11) What besides the cost influences the efficiency of an oil or filter change?
When changing the filter elements you don't need a pit, as the change can be done on the yard. As a result down times are reduced as one change can be done within 15-20 minutes versus 40-45 minutes for an oil drain and oil refill. Filter changes reduce down times because of its longer intervals. Oil change in hydraulics need several hours resulting in even greater cost savings than with engine lube oil changes.

12) What are the costs for an oil analysis?
One test with detailed report is approximately $10.

13) Do you have to add oil between the changing intervals?
Less than with conventional systems as the gaps between piston and sleeve are not made larger through scoring and therefore less oil can be sucked from suction side.

 
Go to topFAQ's Installation :

1) How many filters are needed for hydraulic applications?
For hydraulic equipment there is a CT 30H for less than 200 liters hydraulic oil and a CT 60H from 200 to 1000 liters. For each additional 1000 liters in the system an additional CT 60H is required. (system = tank + circulation) In addition 1 CT 350 pressure reduction valve is necessary. (example: 3200 liters = 4 filters).

2) How many pressure reduction valves CT 350 are needed for the equipment?
As through 1 CT 350 60 liters of oil are running per minute, 1 piece is sufficient. This means that a maximum of 12 filters can be used with 1 CT 350.

3) How many filters are needed for the filtration of engine oil?
The quantity is determined by the size of the engine specially by the quantity of oil in the engine. If bigger engines are to be discussed also the power (HP) has to be considered. (See separate filter calculation).

4) How long does the installation last?
Approximately 1.5 hours if all additional installation parts are available.

5) Is training needed for the installation?
Installation instructions are self explanatory therefore no special training is necessary.

6) What does the first installation consist of?
Housing + filter + valve + hoses + installation parts.

7) May the equipment or part of it be reused?
The housing can be reinstalled to another equipment. The filter elements and o-rings are single use.

8) Do OEMs have objections against the installation?
After first objections OEMs are considering the installation for their equipment after the first trials. Potential customers in the past have ordered the equipment with the filters and the agents in order not to loose the order have installed the filters.

 
Go to topFAQ's Performance :


1) What is the filter range in hydraulic?
Up to 0,1mµ with a temperature of below (+) 20°C (Industrial use)

2) What are the changing intervals of hydraulic filters in comparison to CT- filters under certain conditions?
Tunnel/Dusty areas (bad conditions) original: 500 h                        CT: 2.500 h
Sites/dusty roads (average conditions) original: 500 - 1000 h           CT: 2.500 h
Excellent conditions original: 1000 h                                             CT: 2.500 h

3) What are the changing intervals of hydraulic oil in comparison to CT- oil changes under certain conditions?
Tunnel/Dusty areas (bad conditions) original: 500 h                       CT: 10.000 h
Sites/dusty roads (average conditions) original: 500 - 2000 h          CT: 20.000 h
In 95% cases when CT-filters are in use they are changed at 20.000 hours.

4) How does the installatin of the Cleantechnics International filter system effect the regular (spin-on or full flow) filters?
Because the Cleantechnics International filter virtually eliminates particulate contamination there are no contaminants to clog the regular filter thereby increasing the life of that filter to the same change interval as the Cleantechnics International filter. The original specifications for change intervals on the regular filter are no longer relevant after installation of a Cleantechnics International filtration system.

5) What is the percentage of oil lead through the System?
5-10% of the total quantity, depending whether the oil is cold = Thick bodied or warm = thin bodied. This corresponds to 3 - 5 quarts / minute.

6) What does the effectiveness percentage mean in evaluating filtering capability?

The effectiveness percentage indicates how well the filter removes contamination in the fluid's first pass through the filter. Most regular filters are effective down to the 25-30 micron level. These filters will occasionally randomly capture a smaller particulate. The Cleantechnics Internationl filter effectively filters at the 1 micron size 99.5% of the time.

7) What are the changing intervals of engine oil filters in comparison to CT- filters under certain conditions?
Tunnel / dusty area original: 250 h                                CT: 1.500 h
Sites / Dusty roads original: 250 - 500 h                        CT: 1.500 h
Country roads / bye-roads original:15.000 miles             CT: 60.000 miles
Long distance traffic original: 15-20.000 miles                CT: 60.000 miles

8) What are the changing intervals of engine oil in comparison to CT- oil changes under certain conditions?
Tunnel / Dusty areas original: 250 h                           CT: 7.500 h
Sites / Dusty roads original: 250 - 500 h                     CT: 7.500 h
Country roads / bye-roads original: 15.000 miles         CT: 360.000 miles
Long distance traffic original: 15-20.000 km                 CT: 360.000 miles

9) Does the system influence additives?
As additives are working within a molecular range they are neither removed nor influenced.

10) How does the installation of the CT-system influence the combustion?
Conventional:    gas passes marks, bad compression
CT:                   better flame picture; power utilization 3 - 5 %

11) How does the installation influence the engine performance and the lubrication slit?
Conventional:         lubrication slit becomes wider, power reduced
CT:                       slit, compression remain - no reduction of power

 
Go to topFAQ's Safety :


1) Which safety measures are available if a pressure valve in the hydraulic fails?
The pressure reduction valve necessary for the hydraulic filtering system closes immediately.

2) What pressure are the pressure housings designed for?
Permission for 6 bar; test certificate for 8 bar.

3) Can heat cause the oil to collapse?
Yes, therefore the temperature of the oil should not exceed 95° C

4) What happens to the additives if for a longer period no oil is added?
The additives remain stable. Additives are incorporated into oil to slow oil degradation from the introduction of contaminants. The Cleantechnics International filtration system through the virtual elimination of contaminants does not allow for the depletion of additives.

5) How can the function of the filter be confirmed on vehicles?
The filter housing has a certain radiation heat created by the hot oil passing through. Should the system not work correctly the housing will not get warm.

 
Go to topFAQ's Additional :


1) Comparison with other by-pass filters with regard to higher oil consumption?

About 20-25 years ago a system was introduced to the market which was able to remove particles up to 15mµ. In this system the hydraulic stop light switch was removed and replaced by a tee-piece. The connections at the tee-piece then were: a) stop light switch, b) by-pass filter. From the by-pass filter the oil was lead to an opening in the valve cover where an insert nut was put in. As through this opening more oil was entering the engine room as needed, an overpressure was achieved and a lot of this oil was burned causing that more oil had to be added. This system failed because the oil was led back in the wrong way.
