Product Overview
The SOLARY NH7 is a magnetic induction heater for rusted nuts and other suitable automotive fasteners. Its 1100W specification and eight-coil package offer repair shops a defined setup for localized heating before attempting removal. A plastic carrying case stores the heater and coils together. For equipment importers, the key ordering choices are supply voltage and coil configuration.
Five Key Benefits
- Heat the selected nut: Induction heating concentrates the heating task at a suitable metal fastener before removal.
- Round and flexible coils: The kit covers Ø25, Ø30 and Ø45 mm round coils plus 600 mm flexible coils.
- Pairs for each size: Two pieces per listed coil type make the kit contents straightforward to check at receiving.
- Defined electrical requirements: 1100W power and 10A/5A rated current help buyers assess the required supply version.
- Packing for workshop storage: The plastic carrying case keeps the main unit and coil assortment together for storage and transport.
Applications
Rusted fasteners in automotive steering and suspension service, nut and bolt heating on suitable mechanical assemblies, and repair-bench tasks where coil access is available. Localized heating can assist removal but does not guarantee that every seized fastener will release.
