How to choose the power of the transformer oil filter?

Choosing the right power rating for a transformer oil filter machine depends on several factors, including the oil volume, processing speed, and transformer capacity. Below are the key considerations:

1. Capacity & Flow Rate

• The power of the machine is directly related to its flow rate (measured in liters per hour or LPH).
• Small transformers (≤ 1MVA): 600–1200 LPH
• Medium transformers (1–10 MVA): 1800–3000 LPH
• Large transformers (10–100 MVA): 4000–10,000 LPH
• Extra-large transformers (>100 MVA): 10,000+ LPH

2. Heating Power (kW)

• Transformer oil needs to be heated for effective purification.
• Small systems: 5–15 kW
• Medium systems: 15–40 kW
• Large systems: 40–100 kW

3. Vacuum Pump Power

• A high vacuum system is crucial for degassing and dehumidification.
• Vacuum pump capacity depends on the flow rate and system size.
• Smaller units: ~2–5 kW
• Larger units: 5–15 kW

4. Working Environment

• Consider power supply compatibility:
  • Single-phase (220V) for small systems
  • Three-phase (380V/415V/440V) for industrial use

5. Additional Features

• Two-stage vacuum for ultra-purification.
• Regeneration system for acidity and sludge removal.
• Online operation for continuous filtration without shutting down the transformer.
