Canadian Manufacturer Advances Transformer Oil Production with Stainless Steel Filter Press

A leading Canadian producer of bio-based transformer oils has significantly elevated its production standards by implementing a stainless steel plate and frame filter press. This advanced filtration system specializes in processing rapeseed oil at elevated temperatures, ensuring premium product quality for the electrical industry.

Meeting Specialized Production Requirements
The manufacturer faced unique challenges in their transformer oil production:

Processing rapeseed oil at 80–100°C with magnesium oxide adsorbent

Handling a 1% sediment load (5–50 µm particles) within strict time constraints

Maintaining food-grade standards for technical oil applications

Achieving a filtration capacity of 10 m³/h for 10,000–20,000L batch sizes

Technical Excellence in Design

High-Efficiency Filtration:

50m² filtration area with 750L cake capacity

38 plates and 39 frames (800×800mm) made of 316 stainless steel

Double top-corner feeding for optimal flow distribution

≤0.6MPa operating pressure at temperatures up to 100°C

Food-Grade Construction:

Full 304 stainless steel frame with grinding and brushing finish

316 stainless steel filter plates (12mm thickness)

HG standard flanges with DN80 inlet/DN50 outlet connections

Compliance with food and technical oil material requirements

Operational Advantages:

Automatic hydraulic clamping system

Manual plate pulling for precise control

Closed-flow discharge to maintain oil quality

Transformative Results
The installation has achieved:

Consistent filtration capacity of 10 m³/h within 1–2 hour batch cycles

Effective retention of magnesium oxide particles (1% sediment load)

Maintenance of oil quality standards at high operating temperatures

Reduced downtime through efficient manual discharge operation
