hot tub elements heater

Product Applications

Life appliances: household/commercial hot tubs, spa constant temperature systems, hotel swimming pool heating modules.

Industrial equipment: hot spring/SPA constant temperature circulation system, ship deck hot water unit, agricultural greenhouse water circulation heating.

 製品パラメータと仕様

Power range: 3kW–15kW (customizable to 20kW, suitable for large commercial hot spring/swimming pool systems).

Working voltage: 110V/220V–480V AC (single-phase/three-phase compatible, supports global power grids).

Resistance value: 5Ω–100Ω (accurately matched by voltage and power, error ≤±3%).

Working temperature: 80°C–100°C (continuous and stable operation, short-term tolerance of 120°C).

素材：

Heating element: stainless steel 316L (corrosion-resistant model, suitable for chlorine/salt water environment).

Insulation layer: high-purity magnesium oxide ceramic (hydrolysis-resistant and thermal shock-resistant).

Dimensions: length 150mm–1m, diameter Φ10mm–25mm (supports U-shaped, spiral or flat customization).
​​Service life: 15,000–40,000 hours (based on water quality and maintenance, anti-oxidation coating extends life).
​​Customizable service: supports power, voltage, length adjustment, explosion-proof coating, special threaded interface and other requirements.

コアの利点

Corrosion-resistant design: 316L stainless steel is resistant to salt water/chlorine corrosion, and its life is 50% longer than that of ordinary stainless steel.
​​Efficient thermal conductivity: thermal efficiency ≥ 92%, rapid heating to the set temperature, and reduced energy consumption.
​​Safety protection: IP68 waterproof rating, anti-leakage protection (compliant with UL/CE standards).
​​Long-term stability: magnesium oxide ceramic insulation layer resists hydrolysis and reduces scaling effects.
​​Flexible adaptation: U-shaped/spiral design adapts to narrow spaces (such as hot spring pipe integration).
​​Intelligent temperature control: supports ±3°C PID temperature control to prevent overheating or dry burning.
​​Global adaptability​​: compatible with 110V/220V voltage, adapted to European, American/Asian market standards.
