HRSF TYPE
The HRSF TYPE is our flagship radiator manufactured with MEIDENSHA's advanced technology. The optimized panel cross-section design achieves approximately 30% reduction in oil quantity and 6% increase in heat dissipation area compared to conventional types, contributing to lighter and more compact transformers.
Key Advantages
- Lightweight: Reduced oil quantity enables lighter transformer systems
- High Cooling Efficiency: Increased heat dissipation area with optimized panel design
- Retrofit Compatible: Same pipe diameter (100mm) and panel width (380mm) as conventional types
- Proven Durability: Passed 30-year equivalent fatigue tests and destruction tests
