СММur-1L mobile oil plant
The СММur-1L continues the excellent functionality of this series of equipment, but is designed to be more compact and economical.
The СММur-1L purifies electrical insulation oil with viscosity below 70 cSt at 50o, removing water and particulate matter.
This device can heat oil-filled electrical equipment with hot transformer oil and evacuate air from vacuum systems.
The unit ensures oil purification according to class -/14/12 from initial class -/18/16 (contaminant content by weight less than 0.004%) after multiple passes of the product through the filters.
The СММur-1L is used in the course of commissioning, repairs and operation of oil-filled high voltage systems (power transformers, high voltage switches etc).

Note: * Initial oil parameters:
- moisture below 0.005 % (50 ppm);
- oil heated to +60±5 °C (140±41 °F) for 30 minutes;
- gas content below 10 %.
- Compactness. Due to that fact, the unit can be transported by various means of transport (land, water, air) and won’t take a lot of work space.
- Ease of maintenance and operation. Only one person is required to work with CMM-1 and we can fast and easily teach your staffl how to operate the unit. The constant presence of an operator is not necessary.
- It can raise the breakdown voltage of insulating oils from 15 to 75 kV in several passes.
- It has an increased heating rate due to the optimal design of the heater.
- The big size of the viewing glass window allows you to visually observe and control the process of oil purification.
