Overview

Oil is drawn into the high vacuum oil dehydration system. as oil enters this system, the primary filter is used to prevent particles from entering the system.

The oil is safely and efficiently heated using low watt density heaters operating, the heater is thermostatically controlled to protect the oil from overheating.

The oil then enters the vacuum chamber. Zhongneng ZYD series uses a unique cascading distribution plates design for the chamber. A low maintenance rotary-piston compound-vacuum pump is used to provide a deep and consistent vacuum. The vacuum chamber system provides the following benefits:

System vacuum less than 5Pa.

Vacuum pump maintains consistent vacuum and discharge volume

High water handling capability

High oil / water / gas separation due to the chamber design of Duplex 3D stereo-evaporation and UK G technology application.

Restores the oil dielectric strength to manufacturer's original specifications by ASTM method D1816

Water removal from 100 ppm to < 10 or 50 ppm to < 5 ppm

Gas removal from 12% by volume to less than 0.1% by volume

Filters 99% of particulates > 1 microns

High and low level system controls for safe operation

Oil exits the vacuum chamber by way of the outlet pump. The outlet pump enables the system to return the oil to the equipment at a consistent system flow and discharge pressure.

The oil then passes through a cartridge filter assembly. This filter is used to remove particulates down to 0.5 microns.

All high-vacuum oil purification units are supplied with a bypass valve assembly that enables the unit to also be used as a transfer system. The system also has a valve assembly that allows the treated oil to return to the system for additional processing. With optional control equpment the vacuum system can also be used

to evacuate electrical utility equipment and restore original vacuum levels.
