heating plate for coffee

Product Applications

Home appliances: semi-automatic coffee machine, capsule coffee machine, espresso machine, moka pot heating base.

Industrial equipment: commercial fully automatic coffee machine

Product parameters and specifications

Power range:
Home use: 500W–1500W (drip coffee machine, capsule coffee machine)
Commercial use: 1500W–5000W (fully automatic coffee machine, commercial espresso machine)
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%).

Working temperature:
Standard model: Constant temperature range of 80°C to 100°C (appropriate for hand-brewed/drip coffee), continuous and stable operation.
High temperature model: short-term tolerance of 120°C (espresso’s high temperature extraction demands fit this).
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 options include Teflon (PTFE, anti-adhesion) or ceramic coating (resistant to high temperatures up to 500°C, anti-coffee oil penetration).
Self-limiting temperature characteristics of PTC ceramic chips 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

Accurate 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 second 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 the 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.
​​Intelligent compatibility:
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.
