puraDYN Onboard Oil Management System (OOMS)


puraDYN Filter Technologies Inc., Boynton Beach, Florida

Applicant & Manufacturer:

puraDYN Filter Technologies Inc.
3020 High Ridge Road, Suite 100
Boynton Beach, Florida 33426

Technology Description:

OOMS is an engine oil bypass purification system that extends oil drain intervals. This system features a canister that can be mounted on the fire wall, fender well, engine, or frame of the vehicle, as long as the return line is above the oil pan. The canister inlet is connected to the engine’s oil pressure sending unit or oil galley. The canister outlet is connected to the pan, engine block, or valve cover so that oil gravity feeds back into the engine oil system. The canister electric heating element is connected to an electricity source that supplies current when the engine is operated. The canister houses a disposable long-stranded cotton filter element and an evaporation chamber containing the heating element.

Engine oil enters the canister via a metering jet that restricts the flow to approximately six gallons per hour. The oil passes though the cotton filter element where particles larger than one micron are removed. Filtered oil flows over a diffuser plate and is heated to approximately 195 degrees Fahrenheit in an evaporation chamber. Fuel, water and coolant evaporated by the heated diffuser plate vents to the air cleaner. The filtered and treated oil flow returns to the engine sump by gravity flow via a flow meter and return line.

Certification Statement:

puraDYN’s Onboard Oil Management System (previously known as TF Purifiner’s Electric Mobile Oil Refiner), a bypass oil filtration system for internal combustion engines, is certified by Department of Toxic Substances Control (DTSC) as a Pollution Prevention technology when installed, operated, monitored, and maintained according to puraDYN’s standards and specifications. This certification is specific to reduction of engine oil usage and used oil generation (no life-cycle analysis was performed). The system has been shown to be an effective means of extending engine oil change intervals through the removal of particulate, water, coolant and dissolved fuel. Extension of drain intervals reduce:

1) use of new oil,

2) generation of used oil, and

3) potential of spills while draining and transporting used oil.

If properly operated, monitored, and maintained, puraDYN’s OOMS maintains the following engine oil properties within acceptable limits for continued use: viscosity and solids content, water, coolant, fuel, wear metals, and oil additives. These properties may not be maintained within acceptable limits if major system failures occur, such as: faulty head gaskets that leak coolant into the crankcase, faulty fuel injectors that leak fuel into the crankcase, oil cooler leaks, etc.

Engine oil drain cycles vary according to engine type, fuel quality, oil type, oil consumption rate, work environment, and engine loading. Extended oil drain cycles depend on elimination of harmful contaminants. Oil analysis is recommended as an essential tool in determining maximum drain intervals and to prevent engine failure.

Certification Limitations/Disclaimer:

DTSC makes no express or implied warranties regarding TF Purifiner’s products or equipment. Nor does DTSC warrant puraDYN’s products or equipment to be free from defects in workmanship or material caused by negligence, misuse, accident or other causes.

DTSC does believe, however, that the manufacturer’s product or equipment can achieve performance levels as described in the certification. Said belief is based on a review of three additional years of data from end-users, current and previous data submitted by the manufacturer, and interviews with current and previous end-users of the equipment who have used the equipment in accordance with the manufacturer’s specifications.

Limited testing was conducted in 1994 under the direction of DTSC to confirm the data submitted by puraDYN or collected from other sources. In addition, limited testing was conducted by C.F. Services of Woodland, California for a demonstration project funded by a 1997 grant from the California Integrated Waste Management Board. No additional testing was performed by DTSC for the re-certification.

By accepting the certification, the manufacturer assumes, for the duration of the certification, responsibility for maintaining the quality of the manufactured equipment and materials at a level equal or better than was provided to obtain the certification. The manufacture also agrees to be subject to quality monitoring by DTSC as is required by the law under which the certification was granted.

Certification Basis:

The basis of the evaluation was to determine if, by extending oil change intervals, the OOMS would reduce the generation of waste oil without adversely affecting engine wear or performance. The evaluation of the effect on engine wear included both qualitative information and quantitative data.

End-users provided data from typical real-world operating conditions. The data covered longer intervals of time, had a greater variety of uses, and had greater variety of conditions than those from a controlled test or demonstration. Several end-users and their oil analyses from independent laboratories, which had no commitment to puraDYN, helped make up the bulk the data used for re-certification.

Also, a demonstration project was conducted by C. F. Services of Woodland California and was funded by a grant from the California Integrated Waste Management Board. The demonstration successfully showed that the OOMS reduced the use of new oil in internal combustion engines.

The demonstration project included:

22 trucks (types: long bed, dump, flatbed, sign, water, and service)
4 pickup trucks
13 buses
3 scrapers
2 bulldozers
2 compactors

puraDYN is committed to provide a quality product, maintain and improve their product, and backup their product with a 10-year warranty and a million-dollar certificate of liability insurance.

System Specifications:

OOMS come in six different models depending on oil sump capacity (8, 12, 24, 40, 60, 240 quarts). The devices can also be used in multiples for extra large sumps. The OOMS comes with all the mounting brackets, stainless steel hardware, aircraft quality hose fittings, and complete instructions for installation and maintenance of the unit. Replacement filter elements and other optional equipment are sold separately.

Operation and Maintenance Requirements:

In engine applications using model # TF 8SP, the unit is designed for oil sumps up to eight quarts in capacity. puraDYN’s servicing recommendations state that the OOMS oil filter element be replaced every 12,000 miles or 300 hours or as oil analysis dictates after an initial one half normal interval. Also in engine applications using the model # TF 8SP, puraDYN’s OOMS servicing recommendations state that the standard full-flow oil filter should be replaced every 50,000 miles or 1,250 hours or once a year, whichever comes first. In all other models, puraDYN’s servicing recommendations state that after the first one half normal interval, change the OOMS filter element at a normal periodic maintenance interval or as oil analysis dictates. puraDYN also suggests, on all other models, the OOMS be changed every 12 months or 60,000 miles or 1,500 hours which ever comes first. puraDYN suggests no oil changes unless specified in an oil analysis report.

Regulatory Considerations:

The California Air Resources Board has determined that installing the OOMS will not “reduce the effectiveness of the applicable vehicle pollution control system and, therefore is exempt from the prohibitions of Section 27156 of the Vehicle Code for installation on all 1998 and older model-year vehicles with pressure oil systems.”

Used oil and oil filter elements are presumed to be hazardous wastes, unless determined to be nonhazardous, and must be properly managed via disposal at certified oil collection centers or permitted facilities. Used oil from extended drains and from crushing of oil filter elements must be transported to a permitted used oil recycling facility.
