thick film heating system

Product Applications:

Commercial baking equipment, industrial tunnel ovens, medical sterilizers, laboratory tube furnaces, chemical reactors, ceramic sintering equipment, food processing hot air systems, constant temperature control devices, semiconductor baking equipment, and new energy battery thermal management.

Core parameters​​

​​Power density​​: 0.5–5 W/cm² (local high power area can be customized, such as PTC self-limiting temperature module).
​​Working voltage​​: DC 12V–400V (supports wide voltage adaptation, such as 12V car/220V home).
​​Working temperature​​: continuous 200°C–600°C (short-term peak 800°C, heat dissipation design required).
​​Heating speed​​: 3–10 seconds to reach the set temperature (no thermal inertia, response speed is 50% faster than traditional heating).
​​Material and structure​​:

Substrate​​: alumina ceramic (high temperature resistance > 800°C) or stainless steel (better thermal conductivity).
​​Heating layer​​: ruthenium/tungsten resistor slurry (thickness 10–100μm, sintered into micron-level circuit).
​​Protective layer​​: glass glaze or polymer coating (moisture-proof and corrosion-resistant).
​​Service life: 10,000–50,000 hours (no mechanical loss, life far exceeds PTC ceramic heater).
​​Customizable:
Supports special-shaped cutting, flexible substrate (radius of curvature ≥ 2 times thickness).
Integrated NTC temperature sensor, PWM power modulation interface or IoT module (Wi-Fi/Bluetooth).

​​Product advantages

​​Extreme heating: 3 seconds to 90°C (coffee machine, portable heater scene).
​​High power density: 5 W/cm² high power output, adapted to industrial catalytic heating needs.
​​Precise temperature control: PID algorithm supports ±0.5°C accuracy (laboratory thermostat, medical equipment).
​​Resistant to extreme environments: Ceramic substrates are resistant to acid and alkali corrosion (chemical reactors, oil pipeline heating).
​​Lightweight design: Substrate thickness 0.3–1.5mm, reducing equipment weight (automotive electronics, portable home appliances).
​​Safe and reliable: self-limiting temperature technology + overheat protection (anti-dry burning, explosion-proof certification).
​​Long life: no mechanical wear, life is 3-5 times longer than traditional heaters.
