A simatherm demonstration at Häny AG in Switzerland
 

When a long-standing customer reaches out after more than 20 years of reliable service from one of our simatherm induction heaters, it tells two stories at once. It speaks to the durability of our products, and it signals that the time has come to take the next step.

That is exactly what happened when we visited Häny AG, the renowned Swiss pump and systems specialist headquartered in Jona, canton of Sankt Gallen. Founded in 1875, Häny has built a strong reputation across municipal water supply, wastewater disposal, industrial process pumping, and grouting systems for underground construction. Their operations demand precision, and the components they work with reflect that — ranging from standard rolling bearings to large, coated workpieces that require careful thermal treatment during assembly.

Why induction heating matters for coated components


Many of the parts Häny works with feature protective coatings. Traditional heating methods such as hot oil baths, open flames, or ovens pose a real risk of damaging these coatings, leading to compromised part integrity and shortened service life. Induction heating eliminates that risk. Because an alternating electromagnetic field induces current directly in the workpiece, only the part itself heats up — evenly, precisely, and without exposing sensitive surfaces to external heat sources. The device remains cool throughout. For coated components, this is not just the preferred method. It is the only responsible one.

Starting with the simatherm IH 125

We began our demonstration with the simatherm IH 125, our newest generation induction heater for medium to large-sized workpieces up to 150 kg. With a maximum output of 7.7 kVA, app-based digital control via simatec World of Maintenance, automatic demagnetization, and two-probe technology for stress-free heating of precision bearings, the IH 125 represents the current state of the art. At only 35 kg, it is also the lightest device in its performance class.

The IH 125 performed well during initial testing. However, as we worked through the full range of components that Häny needs to heat on a regular basis, it became clear that their requirements extended beyond what the IH 125 is designed to cover.

The right answer: simatherm IH 210 XL

After evaluating the workpiece dimensions and weights involved, we identified the simatherm IH 210 XL as the ideal solution. The IH 210 handles rolling bearings and other ring-shaped metal parts weighing up to 300 kg, with bore diameters from 60 to 640 mm. Its sliding yoke makes loading and unloading heavy workpieces straightforward, and the five-stage power adjustment ensures that even smaller bearings can be heated safely with reduced energy consumption. The XL version provides a larger working area, giving Häny the flexibility to accommodate the full variety of components they encounter in their day-to-day operations. A 210 kg bearing, for example, reaches the target temperature of 110 °C from ambient in approximately 20 minutes.

What ultimately made the IH 210 XL the clear choice was its ability to cover the entire spectrum — from moderately sized bearings all the way to the largest parts in Häny’s workflow — in a single, compact device weighing just 75 kg including yokes.

Safe handling with the simatool BHT

Heating a heavy workpiece is only half the job. Moving it safely onto a shaft without risking injury or damage is equally critical. That is why we also demonstrated the simatool BHT (Bearing Handling Tool) during our visit. The BHT wraps a steel band around the outer race of the bearing, with two handles and carrying belts that allow safe transport using a lifting crane. The bore remains completely open, so the heated bearing can be placed directly onto the shaft. Anti-twist devices fastened against the inner race prevent uncontrolled rotation during installation, and the tool supports both horizontal and vertical mounting. Available in three sizes for outer diameters from 200 to 700 mm, the BHT is TÜV SÜD certified and purpose-built to work in combination with simatherm induction heaters.

For a company like Häny, where large and heavy pump components are part of daily operations, the combination of induction heating and professional handling equipment is not a luxury — it is a necessity.

A partnership built to last


The fact that Häny’s previous simatherm device served them faithfully for over two decades says a great deal about the value of investing in quality maintenance tools. With the IH 210 XL and the simatool BHT, they are now equipped for the next chapter — with greater capacity, modern technology, and the safety standards their work demands.
