Paramètres et spécifications du produit

Gamme de puissance :
Household: 500W–3000W (small heater, water heater auxiliary heating)
Industrial: 3000W–25kW (industrial oven, HVAC pipe heating, hot air curtain)
Tension de fonctionnement : 110V/220V single-phase AC or 380V–480V three-phase AC (global power grid compatible, error ≤±5%).

Valeur de résistance : 2Ω–50Ω (accurately matched by voltage and power, error ≤±3%).

Température de travail :
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).

Matériau :
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.

Avantages principaux

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.

Résistance à la corrosion et longue durée de vie : 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.
