heating element for hot plate

Product Applications

Home appliances: electric kettles, coffee machines, health pots, electric pressure cookers, electric ceramic stove heating plates.

Industrial equipment: commercial cooking equipment, laboratory constant temperature reactors

Product parameters

Type and material:

Nickel-chromium alloy (NiCr): temperature resistance 800°C, resistivity 1.10 Ω·mm²/m, high cost performance, suitable for conventional kettles.

FeCrAl alloy (FeCrAl): temperature resistance 1000°C, low density, thermal efficiency of 95%, life of about 5,000–8,000 hours.

Ceramic heater (MCH): ceramic substrate integrated with nickel-chromium resistor, temperature resistance 300°C, excellent insulation, suitable for ultra-thin design (thickness ≤2mm).

PTC ceramic heater: automatic temperature control (Curie point characteristics), no open flame, high safety level, suitable for health pots/coffee machines.

Power range:

Household standard: 800W–2000W (suitable for 220V voltage, such as electric kettles and health pots).
Low voltage adaption: 12V/24V DC (small portable devices, such as electric kettles for camping).

Working voltage:

Standard voltage: 220V AC (error ±5%), suitable for household sockets.

Low voltage model: 12V–24V DC (need to be customized).

Resistance value:
Customized by power (for example: 1500W@220V ≈ 32.3Ω, error ≤±3%).

Working temperature:

Continuous stability: 250°C–500°C (NiCr/FeCrAl), surface temperature uniformity ≤±5°C.

Safety protection: PTC model automatically cuts off power (power drops sharply when overheating).

Dimensions:

Shape: spiral, sheet, U-shaped (adapted to the arc design of the bottom of the kettle).

Size: 5cm–15cm in diameter (matching the bottom area of common kettles).

Lifespan and reliability:
Regular models: 5,000–8,000 hours (anti-dry-burn design, supports automatic power-off protection).

Core advantages

Safety and durability:
PTC self-limiting temperature: automatic power reduction in case of overheating, no open flame, passed GB 4706.1 (home appliance safety standard) and UL certification.
Anti-dry-burn design: automatic power off when the temperature exceeds the set threshold to prevent the kettle from drying out and being damaged.
Efficient and energy-saving:
NiCr/FeCrAl material heats up quickly (10°C/second), with a thermal efficiency of ≥95%, 30% faster than traditional aluminum heating.
The surface of the ceramic heater (MCH) conducts heat evenly, without local overheating, extending the life of the kettle.
Thin and lightweight:
The ceramic heater is only 1.5–2mm thick, suitable for ultra-thin health pots/coffee machines, and weighs 50% less.
Easy to clean and adapt:
The flat-plate design (such as MCH) fits perfectly with the bottom of the pot, leaving no dead corners and making it easy to clean.
Quiet operation:
No mechanical vibration, suitable for open kitchens or nighttime use.
