Duct Electric Heater
Heating Medium:
Commonly air, nitrogen, flue gas (including hydrogen sulfide, sulfur dioxide, etc.)
Product Reference Parameters: (The 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-based alloy
Resistance Wire Material: Cr20Ni80
4. Temperature Control Accuracy: 0.5 level
5. Temperature Control Range: 0~800℃
6. Control Method: AC contactor or thyristor stepless power regulation.
Product Features:
1. Outlet medium can reach 850℃, while the shell temperature is only about 50℃ (insulation required).
2. High efficiency: up to 0.95 or more, pressure drop less than 2KPa.
3. Fast heating and cooling rates, up to 10℃/S, with stable and quick adjustment. No lead or lag in controlled air temperature, preventing temperature drift, ideal for automatic control.
4. Good mechanical performance: The heating element sheath is made of stainless steel seamless pipe, so under high-pressure air flow, it has better mechanical performance and strength than any exposed resistance wire.
5. Good oxidation resistance: The heating element consists of stainless steel seamless pipe, high-temperature resistant magnesium oxide powder, and high-temperature alloy resistance wire Cr20Ni80. The resistance wire does not come into direct contact with air, preventing oxidation.
6. Durable even when used improperly, with a design life of up to ten years.
7. Clean air, compact size, uniform heating, safe and reliable.
Product Application Fields:
Widely used in aerospace, *** industry, chemical industry, and many research and production laboratories in universities and colleges.
