WITH the introduction of bio-diesel industry has had to face emerging issues surrounding re-evaluation of bulk storage and end-user fuel cleanliness. Bulk storage tanks from 5000 litres to 1 million litres capacity previously did not have the problems faced today.

Water in bio-diesel can be caused by condensation or from the incomplete reaction during manufacturing of the vegetable oils. Some molecules left behind from this incomplete reaction are capable of emulsifying water, therefore making the removal of water, by separator, coalescer, or filters, much more difficult.

The solution to these problems lies with the In-Depth Ultra-Fine Filters that are on the market today and are quite capable of absorbing leftover water as well as holding the contamination to feed only clean fuel to the equipment.

Essential practice at any bulk fuel facility is to pre-filter the fuel on delivery. Not only will this prevent water from the supply tanker entering bulk fuel tanks but also ensures that the fuel in bulk tanks is up to required standards. Upon the distribution of fuel on site, the same process can again be applied using the same fuel filter used during the delivery process. In addition an ultra-fine fuel filter could be incorporated to ultra-clean the fuel pumped to the tanker.

An individual in-depth ultra-fine filter is another solution for diesel equipment.
The filter process mentioned above is not cheap but will more than pay for itself compared to the cost of equipment repairs, downtime and lost production. Give a diesel engine clean fuel and it will run forever.

Lubrication oil
We are in the 21st Century, yet some operators practice oil change outs as they were performed more than 100 years ago. Automatic oil changes at 250 hours or 500 hours are superseded with oil being too expensive to throw away.

Cheap oil filters will cost you money, shorten oil life due to increased oxidation, create high engine wear and cause rapid loss of engine performance, resulting in lower work performance caused by engine sluggishness and slower operation.

Inexpensive lube oil analyzers are now available to analyze lube oil in the field. This type of equipment can and will save you money.

To make your lube oil go further you could install in-depth by-pass oil filters on diesel equipment. Not only will this increase the life cycle of the lube oil, it will also increase the life of the equipment (see graphs) as in-depth filtration will keep your oil clean.

With the by-pass lubrication oil filter installed you may safely increase the oil change-out period to double or triple the normal time (ie 250 hours to 750+ hours). By using proper oil analysis this can be taken even further.

Benefits of a by-pass lube oil filter:

  • Fuel savings
  • Reduced oil costs
  • Reduced downtime
  • Reduced component wear
  • Increased overhaul period
  • Savings on your overall maintenance budget.

How does it work? Without changing the oil flow a small portion (10%) of the oil is taken off the full flow filter, this is filtered through the bypass filter taking oil from the pressure side and returned to the low pressure side (sump). The oil pressure is regulated and maintained by a valve or baffle within the filter system, this side stream of oil is filtered through a 0.5 micron element returning clean oil to the system.

Engine overhauls and/or re-builds are a part of life with significant costs involved but by installing a by-pass oil filter engine life will be extended.

In-depth filters are suitable for biodiesel, diesel, lubrication oils, hydraulic oils and gear oil. Remember – Don’t throw away your good and valuable oil – you paid for it.
