FIELD: treatment plants.
SUBSTANCE: invention relates to drying, cleaning and recovery of liquid dielectrics, preferably, transformer, turbine, aviation and hydraulic oil. System comprises coarse filter, vacuum dryer, stack of ultra purification filters, buffer tank equipped with level sensors, control electromagnetic valve, and connected to vacuum dryer and stacks of ultra purification electrostatic filters, heater, equipped with oil flow relay and thermostat and connected through coarse filters with vacuum dryer and inlet pump, pressure relay for emergency shutdown of station in case of exceeding permissible pressure upstream of coarse filters, reactor for preparing concentrated solution of additives before electrostatic ultra purification filters, vacuum dryer is made with a foam sensor and level sensors connected with solenoid valve, as well as with oil vapour condenser with a level sensor for emergency shutdown.
EFFECT: higher safety, power saving, longer service life of oil.
