CMM-260C Online Transformer Dry-Out System
The GlobeCore CMM-260C is a transformer dry-out system designed for continuous, long-term moisture removal from transformer oil during normal operation.
Moisture is one of the most damaging factors in transformer service — it reduces dielectric strength, accelerates the aging of both oil and solid insulation, and cannot be entirely prevented regardless of maintenance quality or enclosure integrity. The CMM-260C addresses this by connecting directly to the transformer and continuously circulating its oil through a microporous granular sorbent, which absorbs moisture and retains it reliably within its crystal structure — keeping the transformer dry throughout its entire service life.

- 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.
