Unit features
The LowViscosity Unit LVU is intended for offline filtration. The LVU removes
solid particle contamination and free water from diesel fuel.
Diesel fuel is often subject to long storage periods, especially in tanks which
may be used infrequently. As a result, solid particles and water are often
deposited on the bottom of the tank and can then damage pumps and
sensitive components when switching on the motor.
In addition, over an extended period of time free water in a tank provides a
breeding ground for diesel fuel pests (microorganisms such as bacteria,
algae, fungus, etc.).
Both can quickly lead to blockage of the machine filter and to damage to
diesel injection system components. The consequence: impermissibly high
levels of dangerous emissions from the combustion engine. This leads to
high costs for down time, replacement parts, maintenance and repairs.
The use of the LowViscosity Unit LVU minimizes contamination to a system
and prevents expensive system down time. It also helps to avoid the
necessity of early and expensive disposal of diesel fuel.
The filtration unit is suitable for diesel maintenance in:
Tanks on mobile / stationary emergency power units
e.g. in hospitals, shopping centers and power plants
Tanks of portable machines, e.g. harvesting and construction
machinery
Storage tanks e.g. for agriculture and mining
Tanks on yachts and leisure craft
