Description of Finned Tube Duct Heater
1. Radioactive properties: a maximum monochromatic radiation components reached 0.9, the normal total radiation rate is greater than 0.83.
2. Thermal response time: from room normal temperature to a constant value of the radiant panel surface temperatures less than 20 minutes.
3. Degeneration of hot and cold resistance: five alternating hot and cold test of no peeling, no cracking.
| Radiating temperature inhomogeneity | ≤ 15% |

| Using life | > 3000 hours |
Finned Tubular Heaters offer distinct advantages over open coil heaters:
(a) they are safer to operate in that the risk of fire or electrical shock are minimized;
(b) they have a much longer service life;
(c) they are more rugged requiring less maintenance than open coil heaters.
