A high vacuum process is used for dehydrating and degasification of electrical insulating fluids (transformer oil) to increase and maintain their dielectric strength. The processing includes the removal of free and soluble water, free and dissolved air and gases, and particulate matter.
Removes gases
Removes free, emulsified and dissolved moisture
Removes particulate
Stationary, portable or mobile
Flow rates range from 5 – 70 GPM
Designed to fit in a 20’ or 40’ cargo container for ease of transport.
PFM
Power your oil processing equipment & devices all in on container.

During the restoration of a transformer, it is extremely important to remove as much moisture as possible from its internal components. This is accomplished by isolating the empty transformer so that it can be placed under vacuum.
Under these “blank off” conditions, vacuum is pulled down to 0.25-1 torr for an extended period of time. Water will be vaporized and pulled toward the vacuum pumps; with moisture temperatures above 60-70°F. The longer the transformer is left under this condition, the dryer it gets.
The cold trap is used to help the operator in determining that point and which the transformer has reached sufficient dryness.
The operator can end the process with confidence as the process can be recorded from time to time by freezing, metering and comparing the amounts of moisture trapped in the cold trap.
