The immersion heating element designed for water storage, instant and solar-assisted water heaters adopts food-grade 316L stainless steel + nano-ceramic composite insulation structure, suitable for 1.5kW-50kW power range, temperature resistance up to 1000℃ (short time), and pressure resistance level 20bar.
MOQ:1000PCS
Lead time:25days
Factory location: Zhongshan, Guangdong, China
Home appliances: water storage electric water heaters, instant water dispensers, solar auxiliary heating modules, embedded coffee machines.
Industrial equipment: commercial boiler circulation systems, swimming pool thermostats, food processing high-temperature sterilization equipment, ship fresh water heaters.
Power range:
Household: 1.5kW–3kW (storage/instantaneous water heater)
Commercial: 3kW–10kW (continuous hot water supply, suitable for hotel/catering industry)
Working voltage: 110V/220V single-phase AC or 380V three-phase AC (global power grid compatible, error ≤±5%).
Resistance value: 5Ω–30Ω (accurately matched by voltage and power, error ≤±3%).
Working temperature: Continuous and stable operation of 75°C–95°C (short-term tolerance of 120°C, suitable for high-temperature disinfection needs).
Material:
Heating element: food-grade stainless steel 316L (corrosion-resistant, anti-scale deposition) or copper-nickel alloy (extremely fast thermal conductivity, high-temperature oxidation resistance).
Insulation layer: high-purity magnesium oxide ceramic (hydrolysis-resistant, thermal shock-resistant, and leakage-proof).
Dimensions: Length 100mm–400mm, diameter Φ8mm–20mm (supports U-shaped, spiral or plate customization).
Service life: 10,000–25,000 hours (based on water quality and cleaning frequency, anti-scaling coating extends life).
Customizable services: support power, voltage, shape adjustment, optional anti-scaling coating, dual-zone temperature control, explosion-proof certification, etc.
High-efficiency anti-scaling:
Magnesium oxide ceramic insulation layer + stainless steel/copper-nickel alloy material, anti-calcium magnesium scale deposition efficiency ≥90%, reducing cleaning frequency by more than 70%.
Surface nano-hydrophobic coating technology, anti-scaling performance is 3 times higher than traditional heating tubes.
Fast heating:
The thermal conductivity of the copper-nickel alloy heating element is ≥150W/m·K, and it heats up to 90°C within 30 seconds, which is suitable for instant water heaters.
Precise temperature control:
±1°C temperature control accuracy, supports segmented heating (preheating/constant temperature/fast heating), prevents overheating or hot and cold.
Corrosion-resistant design:
316L stainless steel is resistant to hard water corrosion (pH 6–8.5), copper-nickel alloy is resistant to high temperature oxidation, and its life is 40% longer than ordinary models.
Safe and reliable:
IPX7 waterproof rating, overheating/overpressure dual protection (≥95°C automatic power off), in line with CE, UL, CCC safety certification.
Compact adaptability:
The ultra-thin spiral design is seamlessly embedded in the water storage tank or instant water heater, suitable for home/commercial scenarios.
Smart control compatibility:
Supports PWM power regulation and IoT access (APP remote control of water temperature), and is suitable for smart water heater systems.
Global adaptability:
Compatible with 110V/220V voltage, supports CE, FCC, RoHS certification customization, and is suitable for European, American, and Asian markets.
