The unit is built as a self-contained unit with all components and operating assemblies protected by metal panels and easy opening gas-spring loaded doors on the sides and back of the unit. The “Containerized”unit is placed on a tandem axle trailer that is street legal and ready to be towed to any remote location.
The unit consists of a vacuum1Vacuum is space devoid of matter. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. chamber, input and output oil pumps, coarse and fine filters2Filter is a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass., oil trap, oil heater3Oil heating is used for treatment of oil in degassing, drying and regeneration machines to accelerate the process. Dehydration is based on the difference of water and oil boiling points. Since water boiling point is lower, heating can evaporate that water from the oil before the boiling point of oil is achieved., pipelines with valves, vacuum pump4A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. section and a control cabinet.

Manual performance adjustment by valves (or smooth performance adjustment, see option). Functioning in semi-automatic modes. Stepped or smooth (see option) oil heating. PLC control
Automatic performance adjustment. Functioning in automatic modes. Smooth oil heating. Control from PLC + HMI
Performance adjustment with manual valves
Performance adjustment of the oil pump is executed with a regulator on the control panel by means of a valve with an electric drive. Visual monitoring of the flow rate is by the flow meter indicator
Performance adjustment of the oil pump is executed by setpoint selecting at the control panel screen for maintaining the level in the vacuum column. Pump operation is smooth throughout the entire control range. There is a digital meter to control oil flow
The controller program switches the heater stages by contactors according to the algorithm. Operator sets the temperature and it is kept constant automatically
Solid state relay (SSR) adjusts the heater stages’ current smoothly and non-contactly. The P-Int-Derivative Controller

The 10 ppm mode is the standard operating mode of the equipment, which involves drying oil using thermal vacuum technology.
The 5 ppm mode ensures a very low level of residual moisture in the oil by reducing machine productivity. This means that the equipment effectively removes even the smallest traces of water, which significantly extends the service life of the equipment.
The 5 ppm+ mode is an improved version that ensures even lower residual oil moisture levels by using sorbent cartridges and reducing machine productivity. This is ideal for critical applications especially for heavily loaded transformers with high demands.
Capacitive transducer determines the activity of water dissolved in the oil and converts it into the absolute moisture content of the oil which entered the unit
