Oil Heating

The oil to be treated is heated by means of an electrically heated, PID controlled oil heater, which is brought to the required treating tem- perature. The heating elements are placed into welded-in protection tubes, separated from the oil. The horizontal position and gene- rously dimensioned heating surface allow a careful heating-up of the oil.

Online Oil Measuring

A new measuring instrument for the determination of the oil quality at the in/ outlet of the plant guarantees an opti- mal treating duration. Data is continuously registered on a 6-channel recorder

Degassing System

The degassing system has been opti- mised and expanded with an auto- matic froth control. New is also the automatic level control, dependent on the adjusted flow-through rate. Excellent degassing values and superior oil quality are guaranteed

Filtration

• A built-in pre-filter at the inlet of the VOP plant protects the plant against coarse contamination
• Fine filtering of the oil is carried out by means of easy to exchange filter car tridges with automatic control of dirtyness
• The filter elements are made of special synthetic material and are non-hygroscope.

Oil Feeding

Conveying of oil in the degassing phase is carried out by means of differential pressure. A frequency controlled feeding pump allows for variable oil flow-throughs. A specially developed automatic screen guarantees an even oil flow-through in the degassing phase. A photo electronical level surveillance controls the maximum admissible oil level in the degassing tank.

Vacuum Plant

For the evacuation of gasses, developed in the degassing tank, only rotary slide vane vacuum pumps are now used. To achieve lower guarantee values only the suction capacity of the vacuum pump is increased
