Custom / Non-Standard Transformer Radiators
Where a requirement falls outside standard panel and header sizing, we fabricate radiators to the customer's own drawing or technical specification — adjusting panel type, header length, flange arrangement and mounting to match. All types of pressed steel radiator construction are manufactured according to the order, not from a fixed catalogue.
Applications
- Cooling for oil-filled distribution and power transformers
- Replacement / retrofit radiators for transformer repair and refurbishment
- Supply to transformer manufacturers and OEMs as a fabricated component
Features
- Drawing-based manufacturing for non-standard sizes and configurations
- All four standard OD panel types available as a base, adaptable to requirement
- Header length, flange size and mounting arrangement set to the customer's drawing
