Induction Brazing HVAC Refrigerant Distributor

Key Features of Induction Brazing for HVAC Refrigerant Distributors

1. Precision Temperature Control
   • Utilizes advanced induction heating technology to achieve ±2°C temperature accuracy, ensuring optimal brazing for delicate refrigerant channels.
   • Dynamically adjusts frequency (20–100 kHz) based on distributor size and copper/brass material properties.
2. Non-Contact & Oxidation-Free Heating
   • Electromagnetic induction provides uniform heating without direct flame contact, minimizing oxide formation on tube surfaces.
   • Reduces post-brazing cleaning requirements by 80%, improving production efficiency.
3. High-Speed Processing
   • Achieves brazing temperatures (850–950°C) in 5–15 seconds, significantly faster than traditional torch brazing (30–60 seconds per joint).
   • Supports high-volume production with cycle times as low as 30 seconds per distributor.
4. Customized Coil Design
   • Tailored induction coils fit complex geometries (e.g., multi-branch distributors, angled nozzles) for precise heat targeting.
   • Segmented coils enable simultaneous heating of multiple joints, ensuring consistent braze quality across all connections.
5. Energy Efficiency
   • Power conversion efficiency ≥92%, consuming 40–50% less energy than gas-fired brazing systems.
   • Compliance with ISO 14001 environmental standards due to low carbon emissions.
6. Process Repeatability
   • PLC-controlled automation with pre-set recipes ensures identical brazing parameters for every part, reducing human error.
   • Real-time monitoring of current, voltage, and temperature via HMI interface guarantees traceable quality records.
7. Material Compatibility
   • Ideal for brazing copper-to-brass, brass-to-brass, and copper-to-steel joints in refrigerant distributors.
   • Works with silver-based filler metals (e.g., BAg-4, BAg-7) to form leak-tight seals compliant with ASHRAE 34 standards.
8. Safety & Compliance
   • Equipped with overheat protection and emergency shutdown systems, meeting OSHA and CE safety regulations.
   • Low electromagnetic field (EMF) emissions (<3 mG) ensure operator safety during long-term use.
9. Reduced Thermal Stress
   • Selective heating minimizes heat exposure to non-brazed areas, preventing distortion of thin-walled tubes (wall thickness ≤0.8 mm).
   • Consistent thermal profiles reduce the risk of micro-cracks in critical refrigerant pathways.
