Multi-Panel Radiator Assemblies & Banks
Individual panels are welded into a complete radiator assembly on a common top and bottom header, then grouped into multi-assembly banks where a transformer's cooling load calls for more surface area. Panel count and bank configuration are set per order and confirmed against the customer's drawing before fabrication.
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
- Panel count and bank configuration built to the customer's specification
- Common header assembly across all panels in a unit
- Suited to both single-assembly radiators and larger multi-assembly banks
