INDUCTION HEATER – EHS/EHSU:4

Models: 4 (3.5/4.0 KVA)
VIVID Induction Heater – EHS/EHSU-4 is designed to heat the Bearings and other shrink-fit components prior to mounting using latest technology intelligent microcontroller based electronic controls.

The life of Bearings and other torque transmitting steel components, which are shrunk-fit on shaft, may get cut short due to rough handling and faulty installation or mounting methods. This can be avoided by expanding them by induction heating for the purpose of mounting of the component.

EHS series is light weight and portable for better performance. It has power capacity of 3.5 / 4.0 KVA. The controls are intelligent microcontroller based programmable electronic controls. It has two operating modes, Temperature mode and Time mode. Both are controlled through feather touch key Board. Both modes can be seen at the time of operation. It can also be used to heat bearings of larger diameter using a pair of Raiser Blocks size 55 x 55 x 125 mm. The unit can also be used to heat a plate of any magnetic material by placing the plate in place of the horizontal yoke across the vertical supports.

FAQ

Frequently Asked Questions

It heats bearings and other shrink-fit components before mounting, so the inner ring expands slightly and slides onto the shaft without force. As the smallest model in the range, it's built for lighter, smaller-scale bearing work.

Temperature mode is useful when you need consistent, repeatable results regardless of bearing material or ambient conditions — it stops once the set point is reached. Time mode is handy when you already know from experience how long a given bearing takes and want a fixed cycle. Both are visible on the display, so you can switch based on the job.

Yes — beyond bearings, it can heat a flat plate of magnetic material placed across the vertical supports, which is useful if your shop occasionally needs to heat-treat or expand flat steel components too.

It's a common first unit for smaller workshops moving away from torch or oven heating, since it's portable, simpler to operate, and lower cost than the heavier models in the range.

You can extend its range using the Raiser Blocks (55 x 55 x 125 mm) for larger-diameter bearings. If you're consistently outgrowing that, the EHS/EHSU:8 is the natural next step.

Yes, it's specifically designed light-weight for this — a single technician can carry it between workstations rather than needing a fixed installation point.
