The Mobile Oil Purification System

is designed to purify oil used in air breathing electrical apparatus such as load tap changers and oil filled circuit breaker units.  The 1200 GPH vacuum oil purification system is housed in a 20’, 5 ton heavy duty enclosed cargo trailer which also houses a 550 gallon (2,100 liter) oil processing tank and a 65KW Baldor diesel generator to provide ample three phase power to operate the purification system.  There is also a small transformer to supply 110V power for interior lights and a spare duel receptacle 20 amp circuit and a 480 volt auxiliary receptacle.
