CMM-15 Oil Degassing Plant
CMM-15 Oil Degassing Plant
The CMM-15 plant is designed for degassing, removal of solids and heating of oil for power transformers with voltage up to 1,150 kV. The processing capacity of the machine is 15,000 liters per hour.
The CMM-15 plant 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 unit consists of a vacuum chamber, input and output oil pumps, coarse and fine filters, oil trap, oil heater, pipelines with valves, vacuum pump 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
Frame open design
Shell is available
Online monitoring the transformer tank oil level. Automatic shutdown of the procesing unit and automatic block of the oil hoses in case of an accident. Automatic performance adjustment option. Automatic smooth direct heating option
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. Setpoint is kept constant by means of a valve with an electric drive. 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.
