Product Overview
The NH7S Induction Heater is an advanced electromagnetic heating solution engineered for professional automotive repair and industrial maintenance environments. Utilizing high-frequency magnetic induction technology, the system generates localized heat directly within ferrous metal components, enabling rapid expansion and efficient removal of seized, corroded, or thread-locked fasteners.
Compared to conventional open-flame heating methods, the NH7S significantly enhances operational safety, thermal precision, and workflow efficiency, making it an essential tool for modern workshops and service facilities.
Core Technology
The NH7S operates based on electromagnetic induction, where an alternating current passes through a coil to create a high-frequency magnetic field. This induces eddy currents within the target metal, generating internal heat without affecting surrounding materials.
- Direct internal heating improves energy efficiency
- Minimal heat dispersion protects adjacent components
- Controlled heating zone ensures precision operation

Key Advantages
- High Power Output (1100W): Enables rapid heating within seconds, significantly reducing operation time
- Flame-Free Heating: Eliminates fire hazards, ideal for use near fuel lines, wiring, and sensitive assemblies
- Precision Heating Control: Targets only the required component, minimizing collateral thermal damage
- Improved Productivity: Reduces disassembly time for rusted or seized fasteners
- Operator Safety: No open flame, reduced risk of burns and environmental hazards
