Double-stage vacuum transformer oil filter price

Time:2025-01-16 13:19:16  Reading volume:

The price of a double-stage vacuum transformer oil filter can vary depending on several factors, including its capacity, features, brand, and the specific requirements for the filtration process (such as the volume of oil being processed, the level of moisture and gas removal, etc.). These systems are designed to remove moisture, gases, and particulate contamination from transformer oil, ensuring optimal performance and extending the life of the transformer.

Here’s a rough estimate of the price range for double-stage vacuum transformer oil filtration systems:

1. Small to Medium Capacity (up to 10-20 MVA transformers)

  • Price Range: $10,000 to $20,000
  • These systems are designed for smaller transformers or for periodic maintenance of oil. They typically feature two filtration stages—one for removing particulates and the second stage for moisture and gas removal via vacuum.

2. Medium to Large Capacity (up to 50 MVA transformers)

  • Price Range: $20,000 to $40,000
  • These systems are used for larger transformers and may include additional features like automatic control systems, multiple filtration stages, and more advanced vacuum dehydration and degassing capabilities.

3. High Capacity (over 100 MVA transformers)

  • Price Range: $40,000 to $70,000+
  • These high-capacity systems are designed for very large transformers and industrial-scale operations. They offer high throughput, robust vacuum systems, and high-efficiency filtration, often with advanced automation and monitoring features.

4. Portable Double-Stage Vacuum Transformer Oil Filters

  • Price Range: $8,000 to $15,000
  • These portable units are designed for use in the field or for servicing transformers on-site. While smaller in size and capacity, they still offer effective filtration for removing moisture and gases.

Key Features Influencing the Price:

  • Vacuum Degassing: The vacuum system is crucial for removing dissolved gases and moisture from the oil. The more advanced the vacuum system, the higher the price.
  • Filtration Stages: Double-stage systems are typically more expensive than single-stage units, but they provide superior filtration by tackling both particulate matter and dissolved contaminants.
  • Automation and Monitoring: Systems with automated controls, sensors, and monitoring for parameters like temperature, pressure, moisture content, and gas levels tend to cost more.
  • Brand and Quality: Established brands with a reputation for reliability and performance often come at a premium price.

Factors to Consider When Purchasing:

  • Capacity and Throughput: Ensure the system matches the oil volume and flow rate required for your transformer.
  • Efficiency of Moisture and Gas Removal: Look for systems with high-efficiency vacuum dehydration and degassing to ensure maximum purification.
  • Portability: If you need a mobile unit for on-site work, consider a portable model that is easy to transport and operate in the field.
  • Service and Support: Consider the availability of spare parts, after-sales service, and warranty when selecting a brand.
