CMM-260C Online Transformer Dry-Out System

Cap: 30 LPH | Sorbent drying | Online

The CMM-260C continuous drying device protects transformers by keeping their oil dry throughout its service life. The unit circulates transformer oil through a microporous granular sorbent, which absorbs and securely retains water. It has a capacity of at least 30 liters/hour (0.13 gpm) and a water absorption capacity of 9 liters (2.4 gal). The device can be connected to transformers of any type and age, with installation taking less than an hour. It dries oil without heating, requires no constant operator supervision, and can be installed temporarily or permanently.

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.

If necessary, the adsorbers can be easily dismantled and replaced with new ones, or the sorbent can be reactivated using the BRPS (BRZ) zeolite regeneration unit.
