Description
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. However, it is possible to protect the transformer with the CMM-260C continuous drying device. This machine is connected to the transformer and keeps it dry throughout its service life by passing its oil through a microporous granular sorbent. Water is absorbed and reliably held in its crystals.

Advantages

• 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.
