Product Applications

Home appliances: electric kettles, instant water dispensers, air fryers, health pots, coffee machine heating bases.

製品パラメータと仕様

パワーレンジ：
Home use: 500W–1500W (drip coffee machine, capsule coffee machine)
Commercial use: 1500W–5000W (fully automatic coffee machine, espresso machine, commercial large-capacity model)
Working voltage: 110V/220V single-phase AC or 110V–240V dual voltage compatible (global power grid adaptation, error ≤±5%).

Resistance value: 5Ω–50Ω (accurately matched by voltage and power, error ≤±3%).

作業温度：
Conventional model: continuous and stable operation of 80°C–100°C (constant temperature mode, suitable for hand-brewed/drip coffee).
High temperature model: short-term tolerance of 120°C (suitable for high-temperature extraction requirements of espresso).
​​Material​​:
​​Base material​​: food-grade stainless steel 304/316L (corrosion-resistant, easy to clean) or aluminum alloy (lightweight, thermal conductivity ≥ 200W/m·K).
​​Surface treatment​​: ceramic coating (resistant to high temperatures up to 500°C, anti-coffee oil penetration) or Teflon (PTFE, anti-adhesion).
​​Heating element​​: PTC ceramic chip (self-limiting temperature characteristics) or nickel-chromium alloy (NiCr, resistant to high temperature oxidation).
​​Dimensions​​:
​​Diameter/side length: Φ50mm–Φ200mm (round/square design, suitable for different coffee machine boilers).
​​Thickness: 3mm–10mm (supports ultra-thin embedded installation).
​​Service life​​: 15,000–50,000 hours (based on water quality and cleaning frequency, ceramic coating extends life).
​​Customizable service: Support power, voltage, shape adjustment, optional explosion-proof certification (Ex d IIB T4), IP protection level (such as IP68), integrated NTC sensor, etc.

​Core advantages

​​Precise temperature control and fast response:

PID algorithm + NTC sensor: ±0.5°C temperature control accuracy, heating to 90°C within 30 seconds, suitable for espresso 3-5 seconds extraction window.

Segmented heating mode (preheating/extraction/insulation) to prevent over-extraction or temperature fluctuations.

​​Efficient anti-scaling and easy cleaning:

Ceramic coating resists coffee oil deposition (anti-scaling efficiency ≥95%), reducing cleaning frequency by 70%.

Stainless steel surface electrolytic polishing (Ra≤0.4μm), no dead corner cleaning.

​​Safe and reliable:

Self-limiting temperature PTC technology: Automatically reduce power when temperature exceeds limit, no external thermostat required, anti-dry burning/anti-burning.
IPX7 waterproof rating (suitable for humid environment inside coffee machine), CE/UL/FDA certified.
​​Energy-saving and durable:
The thermal conductivity of aluminum alloy substrate is 5 times that of steel, and the energy consumption is 20% lower than that of traditional heating plates.
Design without moving parts, the life span is 2-3 times longer than that of resistance wire heater.
インテリジェントな互換性：
Supports Wi-Fi/Bluetooth remote control (APP adjusts temperature/mode), and is compatible with smart home systems (such as HomeKit/Alexa).
Can be linked to the coffee machine flow meter to automatically adjust the power to match the water flow rate.
​​Multi-scenario adaptation:
Compatible with all categories of coffee equipment such as drip, hand brew, espresso, cold brew, etc.
