Application:
Oils inside transformers are mainly for insulating purpose- apart from which they also suppress corona and arcing, and also act as coolants inside the machines. These oils must be maintained absolutely clean and dry in order to achieve and sustain the optimal insulating performance and dielectric strength. Here rises the need for transformer oil purification process. ASSEN ZYD Transformer Oil Purifier Machine is the key to transformer reliability, performance and longevity. Your transformer's insulating oil should be free from moisture, dissolved gases and particles that accumulate as the oil ages. Even some new oils may require treatment to limit these contents to acceptable levels.

Features:
1. Expectations on an effective oil plant for treatment of insulating oil.
2. Suitable for oil treatment, vacuum oil injection and cyclic hot oil drying in the installation and maintenance of large capacity transformers.
3. Easy and failsafe operation.
4. On-line measuring and recording of process parameters.
