Extend Transformer Life: Protect with a Transformer Oil Coalescer for Dehydration and Degassing

Transformer oil is the lifeblood of power transformers, serving as both an insulator and a coolant. The presence of free water, dissolved water, and gases drastically reduces its dielectric strength, accelerates aging, and can lead to catastrophic failures. A Transformer Oil Coalescer is a key component in oil purification systems designed to combat these threats.

The Enemy: Water and Gas in Transformer Oil
Water enters through breathing, leaks, or degradation. Its effects are severe:

• Reduced Dielectric Strength: Increases risk of internal arcing.

• Cellulose Degradation: Hydrolyzes paper insulation, shortening transformer life.

• Corrosion: Promotes rust on internal components.

• Gas Bubbles: Reduce thermal conductivity and cause partial discharge.

Function of a Transformer Oil Coalescer
Integrated into a full oil treatment skid (often with vacuum degassers and particle filters), the coalescer specifically targets the free and emulsified water:

• Oil is pumped through a coalescing filter element made of hydrophilic media.

• This media captures and merges microscopic water droplets into large ones.

• The large water droplets then drain to a collection chamber, removing bulk water efficiently before the oil enters the more energy-intensive vacuum degassing chamber.

Why Choose Lefilter for Transformer Oil Maintenance?
Our Transformer Oil Coalescer systems are engineered for reliability:

• High Flow Rate Designs: For both on-line continuous treatment and offline reclamation projects.

• Compatible Media: Effective with all common transformer oils (Mineral, Silicone, FR3).

• Robust Housing: Designed for the high-viscosity flow of oil at varying temperatures.

• System Integration: We provide complete solutions—coalescers, vacuum degassers, particulate filters, and heaters.
