How it Works
The system pump draws the oil from the bottom filter press valve. The oil passes through the seal-less pump and process monitors. The special water absorbing system removes the moisture from the oil to levels well under 10 ppm on a continuous basis. The oil passes through a final filter and returns to the transformer.
Special Notes for Operation
- This equipment operates on 110 volts.
- Once the Insul-Dryer unit is connected to your transformer, oil samples will be drawn at various frequencies, monthly to quarterly, to see when a filter change is necessary.
- The filter system is easily changed in the field with basic tools.
- The Insul-Dryer unit mounts directly on the concrete pad next to the transformer. No special frames or mounts to the transformer are necessary.
- It is a passive dryer that will not shock the transformer insulation equilibrium.
- Full laboratory services are included for moisture monitoring.
- Predictions for dry-out are based on several factors including the initial percent moisture by dry weight; the size, oil capacity and loading of the transformer; the seasonal operating temperatures of the transformer; age and original design of the transformer.
