Fin-Type Tube Electric Heater——High thermal conductivity finned tube electric heating solution
The finned tube heating element is designed for industrial duct systems, agricultural greenhouse heating and commercial heaters. It adopts stainless steel 316L + nano-ceramic insulation structure, suitable for 500W-50kW power range, temperature resistance up to 400℃ (short time), hot air efficiency ≥95%.
MOQ:1000PCS
Lead time:25days
Factory location: Zhongshan, Guangdong, China
Consumer Appliances: Central heating duct systems, smart home vents, electric radiators.
Industrial Equipment: HVAC air handling units, industrial ovens, warehouse dehumidifiers.
Specialized Use: Greenhouse climate control, cleanroom heating, marine HVAC systems.
Power range:
Household: 500W–3000W (small heater, water heater auxiliary heating)
Industrial: 3000W–25kW (industrial oven, HVAC pipe heating, hot air curtain)
Working voltage: 110V/220V single-phase AC or 380V–480V three-phase AC (global power grid compatible, error ≤±5%).
Resistance value: 2Ω–50Ω (accurately matched by voltage and power, error ≤±3%).
Working temperature:
Conventional model: continuous and stable operation of 150°C–300°C (self-limiting temperature design, anti-overheating).
High temperature model: short-term tolerance of 400°C (customized heat dissipation structure and high-temperature ceramic coating are required).
Material:
Base tube: stainless steel 304/316L (corrosion-resistant and anti-oxidation) or aluminum alloy (lightweight, thermal conductivity ≥200W/m·K).
Fins: Aluminum corrugated/longitudinal fins (increase heat dissipation area by 50% and improve heat convection efficiency).
Heating wire: Nickel-chromium alloy (NiCr, high temperature oxidation resistance) or PTC ceramic chip (self-limiting temperature characteristics).
Surface treatment: Anodized layer (corrosion resistance) or enamel coating (anti-peeling).
Dimensions:
Diameter: Φ10mm–Φ50mm, length 200mm–2000mm (support U-shaped, spiral or flat customization).
Fin spacing: 5mm–30mm (adjustable wind resistance and heat dissipation efficiency).
Service life: 20,000–80,000 hours (based on operating temperature and heat dissipation conditions).
Customizable services: support power, voltage, fin density adjustment, optional explosion-proof certification (Ex d IIB T4), IP protection level (such as IP66), integrated NTC sensor, etc.
Efficient heat dissipation and thermal efficiency: The wavy fin structure optimizes the airflow path through CFD, and the heat convection efficiency is increased by 50%, and the heat exchange rate under forced air cooling is ≥95%. The thermal conductivity of aluminum alloy fins is 5 times that of steel, and the volume is reduced by 60% at the same power, which is suitable for compact equipment.
Self-limiting temperature safety feature: PTC ceramic chip or NiCr heating wire + temperature control module, automatically reduce power when the temperature exceeds the set value, prevent overheating and combustion, and no external thermostat is required.
Quick response and energy saving: Lightweight design (density 2.7g/cm³) + low heat capacity characteristics, heating to 200°C within 30 seconds, energy consumption is reduced by 30% compared with traditional heaters.
Corrosion resistance and long life: 316L stainless steel is resistant to acid and alkali corrosion (pH 1–14), and the anodized layer or enamel coating is resistant to salt spray test ≥500 hours, extending the life by 2–3 times. Multi-scenario adaptability:
Supports IP66 waterproof and dustproof (suitable for bathrooms, outdoor equipment), explosion-proof certification (Ex d IIB T4, suitable for petrochemical environments).
Intelligent compatibility:
Integrated PWM power regulation and IoT access (APP remote temperature control), adaptable to smart home systems (such as HomeKit/Alexa).
Can be linked to temperature and humidity sensors to automatically adjust heating power to maintain a comfortable environment.
