How much does transformer oil purification equipment cost？

The cost of transformer oil purification equipment can vary widely depending on factors such as the type of equipment, capacity, technology, and manufacturer. Transformer oil purification is a critical process to maintain the quality and performance of transformer oil by removing contaminants such as water, gases, dirt, and sludge. There are several types of transformer oil purification systems, including offline filtration, degassing units, vacuum dehydration systems, and regeneration plants.

 Typical Cost Range for Transformer Oil Purification Equipment: 

1. Portable Transformer Oil Purification Units:

   - Price: $5,000 to $50,000+

   - Description: These units are typically used for small-scale or mobile purification of transformer oil. They are often used by maintenance teams to purify oil on-site without removing the oil from the transformer.

   - Features:

     - Vacuum dehydration: Removes moisture from the oil.

     - Filtration: Removes particulate matter and sludge.

     - Degassing: Removes dissolved gases like hydrogen and methane.

   - Capacity: Generally ranges from 100 to 1,500 liters per hour (depending on the size of the unit).

   - Applications: Used for periodic maintenance and small to medium-sized transformers.

2. Stationary Oil Purification Systems:

   - Price: $30,000 to $150,000+

   - Description: These larger units are used for continuous or heavy-duty transformer oil purification, often in power plants or substations. These systems are capable of handling large volumes of oil.

   - Features:

     - Multi-stage filtration and degassing.

     - Vacuum dehydration systems for removing moisture.

     - Regeneration systems (sometimes) for rejuvenating degraded transformer oil.

   - Capacity: Can process anywhere from 1,000 to 50,000 liters per hour, depending on the system.

   - Applications: Used in large-scale power stations, substations, or for handling multiple transformers.

3. Transformer Oil Regeneration Plants:

   - Price: $100,000 to $500,000+

   - Description: These are high-capacity, industrial-grade systems used for large-scale regeneration of transformer oils. They are capable of removing water, gases, particulate matter, and other contaminants to restore transformer oil to near-new condition.

   - Features:

     - Regeneration of oils by removing oxidation products, acidic compounds, and other contaminants.

     - Vacuum distillation or clay filtration for oil regeneration.

     - Often used for dehydration, degassing, and filtration combined.

   - Capacity: Typically capable of processing 10,000 to 50,000 liters per hour.

   - Applications: Used by utilities, large power stations, and transformer maintenance contractors.

4. Mobile Transformer Oil Purification Systems:

   - Price: $20,000 to $100,000+

   - Description: These mobile systems are designed for on-site oil purification for large transformers. They can be used in remote locations or at substations.

   - Features: Includes vacuum dehydration, filtration, and degassing features.

   - Capacity: Ranges from 500 to 5,000 liters per hour depending on the size and model.

   - Applications: Used by electrical utilities and contractors for on-site oil maintenance and purification.

 Factors Affecting Cost:

1. Capacity: Larger capacity systems cost significantly more. Systems that can process thousands of liters of oil per hour will be at the higher end of the cost spectrum.

2. Technology: Systems that incorporate oil regeneration or high-efficiency filtration tend to be more expensive. Regeneration units, which can extend the life of transformer oil, are among the most costly.

3. Brand and Quality: Renowned manufacturers such as Schenck, Olgil, CMM, and Transformers Oil Technologies tend to offer higher-quality and more reliable equipment, which can influence the price.

4. Features: Additional features, such as automated controls, continuous monitoring, advanced filtration technology, and mobility (e.g., trailer-mounted), add to the overall cost.

5. Customization: Custom systems designed for specific transformer oil types or operating environments can be more expensive.

 Popular Transformer Oil Purification Equipment Manufacturers:

1. Schneider Electric (Reconditioned Transformer Oil Purification Systems)

2. Olgil (Oil Purification Units)

3. CMM (Cooperative Maintenance Management)

4. Mobil (Oil Filtration and Treatment Systems)

5. SINO-NSH (Transformer Oil Filtration Systems)

6. Doble Engineering (Mobile Purification Equipment)

 Additional Costs to Consider:

- Installation and Setup: Installation costs can range from $1,000 to $10,000 depending on the complexity of the system and whether it is a mobile or stationary setup.

Maintenance: Regular maintenance, including the replacement of filters and other consumables, will add to the overall cost of operation.

Shipping/Logistics: For large systems, shipping can be a significant cost, particularly for international purchases.

Conclusion:

The cost of transformer oil purification equipment ranges widely based on the capacity and technology used. Smaller, portable units designed for periodic maintenance might cost between $5,000 and $50,000, while larger, more advanced systems, such as stationary or regeneration plants, can cost anywhere from $30,000 to $500,000 or more, especially when specialized for large-scale oil regeneration.

For accurate pricing, it's advisable to contact suppliers directly and provide specific details about the required capacity, features, and intended application. This will allow for customized quotes based on your needs.
