Transformer oil purification is the process of removing impurities, moisture, and gases to restore the oil’s insulating and cooling properties. The process involves heating, vacuum dehydration, and filtration of the oil. After purification, the oil is tested to ensure it meets standards, which helps maintain the transformer’s reliability and extend its lifespan.

An oil furnace ignition transformer generates the high voltage necessary to create a spark that ignites the oil in an oil furnace. This spark initiates the combustion process, allowing the furnace to produce heat efficiently for heating systems.
