Do you have a unique heating application? Look to TM Induction Heating for a fast, flexible , accurate means to apply heat. In the application pictured below, TM was asked to meet a critical heating rate for an expected production line. Utilizing our water cooled EasyHeat 35KW Induction Heating System with a custom made coil, we met the target with excess capacity for future time reductions. The system operates 3 shift per day and has been in service for 3+ years requiring only minor maintenance.
If you are using large ovens, torches, baths or other methods, please let us present you with the latest in heating technology.
Large Commercial Industrial Induction Heater
Roller Stock Bearing removal.
Before machining the wheels of rolling stock, the bearing rings (NU and NUP) and the labyrinth rings have to be dismantled. This is important for the customer as the rings must be dismantled without damage for reuse.
Solution TM: By sliding an induction coil over the inner ring or labyrinth ring and connecting it to a mid-frequency generator, we are able to heat only the inner ring while the shaft stays cool. After heating it is easy to slide the ring and coil from the shaft.
Advantage: Inner ring can be used again, no damage or overheating.
Induction coil is relative light and easy to handle.
A continuously “Temperature Controlled” heating and dismounting process, no chance of overheating the ring or shaft

Assemble Gear Rim Shipyard
Customer Request: A large shipyard in the Netherlands asked us to find a solution for the safe, fast, tension free heating of a gear rim (ø4000mm) prior to mounting on a winch.
Solution TM: TM offered our low frequency induction heater; Easytherm 250-coil. This is an approved heater used in several environments where massive parts are assembled, like the Wind power industry, mining industry etc.
Advantage: The TM Easytherm 250-coil is a standard solution, suitable for different parts with a minimum bore of 500 to a 1000mm. The purchase price is relative low against other heating methods. Small heater dimensions allow easy placement in the workshop. Power consumption is low. It took 15 minutes to heat this part to 80°C with minimal power consumption.

Induction Heating System with double sensor technique
Increased heating quality of metallic work pieces with a central opening and round closed form.
This article describes a newly developed method for induction heating devices. The developed by TM Induction Heating, increases the quality of heating metallic workpieces that form a closed round shape with a central opening (bearing, gears, etc.). Throughout the entire warming process, temperature of the inner, as well as outer regions, are continuously monitored and control power is adapted to insure an optimum temperature differential, negating work piece damage due to residual stress.
Classic induction heaters control the heating process by only monitoring temperature of the inner region (bearing inner ring). Temperature of the outer ring is neglected. This runs the risk that the two rings will not expand evenly (see figure 1). If the inner ring heats too rapidly in relation to the outer ring, large mechanical stresses between rings and roller elements will occur. Damage related to cracks, fractures, or pitting may go unnoticed, reducing the life of the product. One possible method to control this is, is heating in a controlled ramp mode. Experience and careful attention are required to make sure the process differential is within allowable specifications. Differences in work pieces make this method difficult and inappropriate in most situations.
In view of increasing quality demands on the world market, TM Induction Heating has developed Dual Sensor Control to solve this problem. Not only the inner region, but also the outter region temperatures are monitored with a corresponding power adjustment to maintain the optimal expansion ratio. The new SURETHERM heaters provide the operator with a digital readout and graph representation of the heating process through the entire cycle. (see chart 2) This has proven to lead to increased operating life and allows for documented process quality control, ensuring the optimal ratio of heating time and power consumption.
The new SURETHERM models will arrive in the US market this summer. Be sure to contact your local representative or call us at 720-266-4403 for more information.
