New Coil System Available for the AES HI 3.5 Induction Heater. More Flexibility. Lower Replacement Costs. Faster Heating Setup.
The AES HI 3.5 induction heater is already trusted throughout vehicle workshops for the fast removal of seized nuts, bolts, bearings, suspension components and other metal parts. We are pleased to introduce a new range of interchangeable coil accessories that further expand the capabilities of the system.
These new accessories provide greater flexibility when heating components of different sizes, while also reducing replacement costs when compared to replacing complete induction tips.


New Focus Round Coil with Reducer
The new Focus Round Coil with Reducer combines a larger heating area with a replaceable coil core, making it ideal for workshops carrying out frequent induction heating work.
Key Benefits
- Larger round coil heating area
- Improved access around larger components
- Replaceable coil core
- Lower repair and replacement costs
- Quick installation on existing AES HI 3.5 units
Unlike traditional fixed induction tips, the coil element can be replaced independently, helping to reduce downtime and consumable costs over the life of the equipment.

New Reducer for Round Coils
The new AES HI 3.5 Reducer allows operators to quickly fit a range of interchangeable circular coils.
The reducer installs directly into the AES HI 3.5 in the same way as a standard induction tip. Once fitted, circular coils are secured using two grub screws, allowing coils to be swapped quickly depending on the application.
This gives workshops greater flexibility when working on different bolt, nut, bearing and suspension component sizes.

- 53mm - https://www.aesuk.com/induction-heaters/spares/aes-hi-35-reducer-round-coil-53mm
With multiple coil sizes available, technicians can select the most suitable coil for the job, helping to concentrate heat where it is needed and improve heating efficiency.



Ideal for Existing AES HI 3.5 Owners
If you already own an AES HI 3.5, these new accessories provide an easy way to expand the capability of your existing equipment without investing in a completely new system.
The reducer and coil range allow you to tackle a wider variety of heating applications while reducing the long-term cost of consumable parts.
Why This Matters When Choosing an Induction Heater
When investing in workshop equipment, flexibility and long-term ownership costs are just as important as initial performance.
The AES HI 3.5 now offers:
- Standard induction tips
- Interchangeable round coil options
- Replaceable coil cores
- Lower consumable costs
- Increased application flexibility
- Fast changeover between coil sizes
This makes the AES HI 3.5 a future-proof solution for workshops looking to maximise the value of their induction heating equipment.
