CMM-260C Online Transformer Dry-Out System
CMM-260C transformer dry-out system is designed for daily transformer care providing continuous drying from water.
Water is a dangerous enemy of the transformer, reducing the dielectric strength of transformer oil, accelerating the aging of oil and solid insulation. It is impossible to entirely prevent water contamination in a transformer, since it forms regardless of service quality and airtightness of the unit. to protect transformer it id needed to connect CMM-260C to the transformer and it will keep the transformer dry throughout its service life by passing its oil through a microporous granular sorbent. Water is absorbed and reliably held in its crystals.

- connection to transformer of any type and age;
- the process of connection takes less than an hour;
- the sorbent captures water regardless of its temperature and form;
- the machine dries the oil without heating and does not require constant operator control;
- the machine can be installed temporarily or permanently.
