    Advantages
    • the unit is equipped with a centrifugal output pump to reduce noise;
    • the unit does not have an input pump, the oil goes directly into the unit with reduced risk of leaks;
    • simple operation;
    • a porous inset in the vacuum chamber facilitates efficient moisture separation;
    • the smart heating system varies current for the required processing rate, eliminating voltage surges;
    • a water condensate collection container is installed;
    • the unit features a separate outlet for transformer evacuation.

The СММ-1Н unit is designed for drying1Drying is a process of water removal from transformer oil., heating2Oil 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. and filtration3Oil Filtration is a partial removal of solid particles through filter medium. Oil filtration systems generally use a multistage filtration with coarse and fine filters. Centrifugation is separation of oil and water, or oil and solid particles by centrifugal forces. of mineral transformer oil4Transformer oil is an oil that is stable at high temperatures and has excellent electrical insulating properties., as well as evacuation of transformer5A transformer is a static electrical device that transfers electrical energy between two or more circuits. tanks.

The process is based on application of heat and vacuum6Vacuum is space devoid of matter. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure.. The oil is heated and pumped to the vacuum chamber. The low pressure in the chamber makes the water in the oil boil and evaporate. The water vapor is removed with vacuum pump exhaust.

The СММ-1Н unit consists of the following elements: a frame, a centrifugal oil pump (output), a vacuum pump7A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum., an electrical control cabinet, a vacuum chamber, filters8Filter is a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass., an oil trap, piping, an instrument panel, an oil inlet and an oil outlet.

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 vacuum 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 vacuum 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
