The OPS-1 oil purification system is designed to remove contaminants such as water, solid particles, and dissolved gases from oil. It functions similarly to other oil purification systems by using filtration, vacuum dehydration, and sometimes degassing methods. The OPS-1 is specifically built for efficient operation, often featuring automation for monitoring and controlling the purification process. This ensures the oil is restored to its optimal condition for continued use in transformers or industrial equipment.
