What is termovácuo and how is it used in transformer oil drying?

“Termovácuo” (Portuguese for “thermal vacuum”) refers to the combined heating and vacuum drying process used in transformer maintenance. It’s essential for removing bound moisture from insulation and oil. Fluidex equipment supports this process with programmable heating, vacuum down to <5 Pa, and automatic control. Commonly used in Latin America and Europe for transformer drying before oil filling.
