heating element for air conditioner

Applications

Consumer Appliances: Split air conditioners, window units, heat pump systems, portable heaters.
Industrial Equipment: Commercial HVAC heating modules, agricultural greenhouse heating systems, industrial ventilation warm air units.

Product parameters and specifications

Power range:
Household: 500W–2000W (suitable for split air conditioners, window air conditioners)
Commercial: 2000W–10kW (central air conditioners, heat pump auxiliary heating modules)
Working voltage: 110V/220V single-phase AC or 380V three-phase AC (global power grid compatible, error ≤±5%).

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

Working temperature:
Conventional model: continuous and stable operation of 80°C–120°C (self-limiting temperature design, anti-overheating).
High temperature model: short-term tolerance of 150°C (customized heat dissipation structure and ceramic coating are required).

Material:
Heating element: nickel-chromium alloy (NiCr, high temperature oxidation resistance) or PTC ceramic chip (self-limiting temperature characteristics).
​​Heat dissipation structure: aluminum fins (thermal conductivity ≥ 200W/m·K) or stainless steel tubes (corrosion resistant).
​​    Surface treatment: anodized layer (corrosion resistant) or enamel coating (anti-peeling).
​​Dimensions:
Tube diameter: Φ6mm–Φ25mm, length 50mm–800mm (supports U-shaped, spiral or flat customization).
Fin spacing: 5mm–20mm (adjustable wind resistance and heat dissipation efficiency).
​​Service life: 15,000–50,000 hours (based on operating temperature and heat dissipation conditions).
​​Customizable service: support power, voltage, temperature control mode adjustment, optional explosion-proof certification, IP protection level (such as IP68), integrated NTC sensor, etc.

Core advantages

​​Efficient heating and energy saving:

PTC ceramic self-limiting temperature technology automatically lowers power beyond the predetermined range to avoid overheating and combustion and cuts 30% of energy use relative to conventional resistance wire.
Suitable for the rapid heating demands of air conditioners, the nickel-chromium alloy heating element has a thermal conductivity of ≥150W/m·K and a temperature rise to 100°C within 3 minutes.

​​Safe and reliable:

IPX4 protection level: splash-proof design, suitable for humid environments such as bathrooms and kitchens.

Automatic power off when tilted: power off immediately when the tilt angle is ＞10°, in line with UL/CE safety standards.

Precise temperature control and silent operation:
±1°C temperature control accuracy, support segmented heating (low temperature start/high temperature insulation), suitable for variable frequency air conditioner energy efficiency mode.

No mechanical vibration noise, suitable for night sleep mode.

Corrosion resistance and long life:
316L stainless steel or anodized aluminum is resistant to salt spray corrosion (test ≥500 hours), and the life is 2-3 times longer than ordinary resistance wire.

Intelligent compatibility:
Support PWM power regulation and IoT access (APP remote temperature control), suitable for smart home systems (such as HomeKit/Alexa). Humidity sensors can be integrated to link the air conditioning dehumidification mode to prevent heating from causing excessive dryness in the room.
​​Environmental protection and adaptability:
Zero emissions, no odor, in compliance with the EU ErP energy efficiency directive (A+++ grade).
High humidity resistant design (RH 95%), suitable for air conditioning systems in tropical/coastal areas
