Microwave heating tube

Product Applications

Household microwave ovens, built-in ovens, commercial food thawing machines.

Key Parameters & Specifications​

​Power range: 100W–30 kW (adjustable, appropriate for domestic microwaves ranging from 30 kW to industrial ones).
Operating frequency is 2.45GHz (standard ISM band) or 915MHz (industrial/high-power uses).
Input voltage—110V/220V–480V AC ( single-phase or three-phase, internationally compatible).
Output power stability: ±5% (precision control for regular heating).
Magnetron uses tungsten for the cathode, copper for the anode, and high-purity alumina ceramic for the housing.
Waveguide: Corrosion-resistant, aluminium alloy or stainless steel optimised for 2.45GHz/915MHz.
​Efficiency: ≥92% (electric microwave radiation’s energy conversion).
Operating temperature: -40°C to 250°C ( Continuous duty with cooling devices).
​Lifespan (Dependent on cooling efficiency and usage intensity): 5,000–20,000 hours

Core Components & Technology​

​Magnetron:
Generates microwave energy via electron resonance in a strong magnetic field.
Features a ​ceramic insulator​ to withstand high voltages (up to 20kV).

​Cooling System:
Air-cooled or liquid-cooled (Forced-air fans or coolant circulation for heat dissipation).

​Waveguide:
Directs microwaves into the cavity, minimizing energy loss (<3% reflection loss).

​Safety Features:
Overheat protection, door interlock switches, and leakage detection (<5mW/cm² per FDA/IEC standards).

Advantages Over Traditional Heating Methods​

​Rapid Heating:
Heats materials uniformly in seconds (e.g., drying food in 1/10th the time of convection ovens).

​Energy Efficiency:
No need for preheating; targets water/molecule vibration directly, reducing 30% energy waste.

​Process Control:
Programmable power modulation for batch or continuous processing (e.g., pharmaceutical drying).

​Versatility:
Compatible with metals (induction limits apply) and non-conductive materials (ceramics, plastics).

​Space-Saving Design:
Compact form factor for integration into industrial lines or countertop appliances.
