Duct Electric Heater
Heating Medium:
Commonly air, nitrogen, flue gas (including hydrogen sulfide, sulfur dioxide, etc.)
Product Reference Parameters: (Company can also customize according to customer requirements)
1. Input Voltage: 220V, 380V, 400V, 660V, etc.
Can be connected in delta (three-phase three-wire) or Y configuration (three-phase four-wire) as needed;
2. Rated Power: 15KW-2000KW
3. Common Shell Materials: Q235B, 304 Stainless Steel, 316L Stainless Steel
Common Heating Tube Materials: 304 Stainless Steel, 316L Stainless Steel, Incoloy800 Nickel Alloy
Resistance Wire Material: Cr20Ni80
4. Temperature Control Accuracy: 0.5 grade
5. Temperature Control Range: 0~800℃
6. Control Method: AC Contactor or SCR stepless power regulation.
Product Features:
1. Outlet medium can reach 850℃, shell temperature only about 50℃ (insulation required).
2. High efficiency: up to 0.95 or above, pressure drop less than 2KPa.
3. Fast heating and cooling rates, up to 10℃/S, stable and quick adjustment. No lead or lag in controlled air temperature causing drift, ideal for automatic control.
4. Good mechanical performance: Heating element sheath uses stainless steel seamless tube, so under high-pressure air flow, it has better mechanical performance and strength than any exposed resistance wire.
5. Good oxidation resistance: Heating element consists of stainless steel seamless tube, high-temperature magnesium oxide powder, and high-temperature alloy resistance wire Cr20Ni80. The resistance wire does not directly contact air, preventing oxidation.
6. Durable even under improper use, designed service life up to ten years.
7. Clean air, compact size, uniform heating, safe and reliable.
Product Application Fields:
Widely used in aerospace, military industry, chemical industry, and many scientific research and production laboratories in universities and colleges.
