TL-1 burning furnace is consists of 5 parts: natural gas burner + inner tank + insulation box + fan + control system. The burner forms a high-temperature flame after full combustion in the high-temperature resistant inner tank, these flame mixes with the cold or recirculated air to produce a new and high-temperature air. Under the action of the fan, it is discharged to provide heating for drying machines or places. Advantages/features 1. Simple structure and low cost 2. Large air volume and small wind temperature fluctuation 3. Stainless steel high temperature resistant inner tank, durable 4. Automatic gas burner, complete combustion, high efficiency. (After setting up, the system can control the ignition+cease fire+temperature adjust automatic), 5. High-density fire-resistant rock wool insulation box to avoiding heat loss 6. High temperature and high humidity resistant fan with IP54 protection rating and H-class insulation rating.
