Import Bh Series High Frequency Induction Heater — Buy in wholesale FOB from Supplier in China

The Bh Series High Frequency Induction Heater is a solid-state heating system designed for metal brazing, hardening, forging and annealing applications. It employs European MOSFET and IGBT power modules combined with resonance inverter technology to convert mains electricity into high-frequency alternating current for induction heating. The design claims 100 percent duty cycle capability, allowing continuous operation over 24-hour periods, and incorporates digital phase-locked loop control for automatic frequency tracking during the heating cycle. An external infrared thermometer interface enables remote and automatic temperature control without continuous operator presence.

The control system offers three independently adjustable time stages, heating, maintain temperature and cooling, with separate power adjustment for the maintain temperature stage. This staged approach allows rapid initial heating followed by reduced power during thermal soaking, which is particularly relevant for brazing operations where solder flow and joint wetting depend on precise temperature holding. Protection functions include over-current, over-voltage, water shortage and phase-loss detection, with fault states displayed on the operator interface. The output voltage is described as safe for operator contact, though this should be qualified against specific certification standards.

This induction heater targets mass production environments where repeatability and throughput are critical, such as automotive component brazing, tool hardening shops and metal forging facilities. The ability to programme heating curves makes it suitable for workpieces with varying thermal mass or geometry. Buyers should confirm power frequency range, rated kilowatt output, cooling water flow requirements and whether the quoted European semiconductor origin refers to device fabrication or module assembly. Voltage, phase configuration and CE or CCC compliance status should be verified directly with Guangzhou Dragon Welding Co., Limited before purchase.

Guangzhou Dragon Welding Co., Limited is located at Kaili Industrial Zone, No.389, Guangzhu Road, Dagang Street, Nansha District, Guangzhou, Guangdong Province. The company sits within the Pearl River Delta manufacturing corridor, one of China's densest concentrations of industrial equipment producers. It is listed at Harbor trust tier. Response metrics are not available, so initial contact may require follow-up persistence. The address indicates a permanent industrial facility rather than a trading office, though the extent of in-house versus outsourced manufacturing is not stated.

The supplier presents itself as a manufacturer of welding and heating equipment with emphasis on semiconductor component sourcing from European suppliers. No information is provided about year of establishment, factory floor area, number of employees, annual turnover, or client references. Certification claims such as CE, ISO 9001 or CCC are absent from the source material. Buyers should request a factory audit report, quality management system documentation, and reference installations before committing to volume orders, particularly for equipment where water cooling and high-voltage safety interlocks are critical.
