Cleaner Hydraulic Oil Leads To Increased Profits

Cleaner hydraulic oil leads to Increased Profits. Free from contamination provide better service to machines and, in turn, properly maintained machines will provide better, more reliable and profitable service to the owner or operator. A small amount of particulate or water contamination in a machine may not lead to an instant failure or halt of operation today, but will invariably shorten the machines life. When the machine does finally fail it is very difficult to determine or even prove loss of life due to particulate contamination. The general rule of thumb is that it costs ten times as much to remove the particulate contamination as to prevent it occur in the first place. The bottom line is: clean up your act and you will achieve greater machine availability and utilization. Reduced operating cost and increased profits will follow naturally from this.

Approx 80% of all malfunctions in hydraulic oil systems is related to oil-problems, 60% of the malfunctions are because the oil is too contaminated with impurities, such as particles and water.

It is always the weakest part of the equipment that decides the level of cleanliness needed.

To illustrate how important it is that the oil is clean, Danish Technological Institute states that new oil should always be filtrated before it’s used in the equipment.

A machines life:

The liability and lifespan of a machine/hydraulic system depends totally on the oils condition.
At the start of use of a machine, the creation of impurities is at its greatest.
From the first day of use, it is of great importance to secure the cleanliness of the oil,
80% of all malfunctions is because of impurities in hydraulic- oil systems.
By keeping the oil clean at all times, you will secure a long and healthy life of your equipment.

Guidelines preventive maintenance:

• Keep the best level of cleanliness in hydraulic oil
• The cleaner the system, the longer the lifespan of oil and equipment
• A well-defined cleanliness and efficient filtration is of great importance

These types of contaminants must be removed from the system to achieve the longest possible lifespan of the equipment:

Three different sources of contaminants:

1. Maximal lubricating abilities
2. Cleanliness
3. rust and corrosion protection
4. Oxygen content
5. Antifoam abilities
6. Good demulsifying abilities
7. Viscosity
8. Viscosity index
9. Environmental affections

OFF-LINE FILTERING

Contaminations

By using Johnsen oil’s off-line oil filtration, you will save and protect the system and system filters. The system filters are not capable to handle the amount of particles, and are at the same time very expensive.

With Johnsen oil’s off-line oil filtration you will achieve a more efficient filtering which secures a much longer and healthier lifespan of your equipment. This will keep your equipment out of the “80% malfunction” statistics.
