| Type | Max Temperature | Key Features |
|---|---|---|
| L Type | 150°C (302°F) | Cost-effective, suitable for low-temperature applications |
| LL Type | 180°C (356°F) | Overlapping fins for better corrosion resistance |
| KL Type | 260°C (500°F) | Knurled surface for superior heat transfer and vibration resistance |
- Enhanced heat transfer efficiency through knurled surface technology
- Superior corrosion resistance for extended service life
- High vibration resistance in demanding industrial environments
- Maximum operating temperature of 260°C for high-heat applications
- Compatible replacement for various finned tube types
KL finned tubes are manufactured using a specialized knurling process where the base tube surface is textured before wrapping the L-shaped fin strip. This creates a mechanical bond that significantly improves heat transfer performance and durability.
