TWIM 15 230V SKF Portable Induction Heater 230V Version

The SKF portable induction heater TWIM 15 is designed for applications in maintenance jobs to heat up bearings that are mounted with an interference fit onto a shaft. Heating the bearing causes it to expand, which eliminates the need to use force during installation. Generally, using the TWIM 15 to generate a 90 degree celsius temperature difference between the bearing and shaft is sufficient to enable installation. In addition, the TWIM 15 can be used to heat other ring shaped, metallic components, providing flexibility of use.

Utilizing electrical power, the TWIM 15 features glass fiber, high temperature-resistant plastic construction that allows a low temperature difference between the inner and outer rings of the bearing. This helps to reduce internal tensions that are generated due to excessive thermal expansion of the inner ring compared to the outer ring.

The unit has a user friendly LED control panel that requires no special training and is simple to understand. The panel is used to regulate temperature and also indicates that the TWIM 15 is operational.

TWIM 15 advantages:
Innovative heating of bearings
Portable, compact and lightweight
No support yokes required
Automatic temperature monitoring
Detects bearing size and heats appropriately
Different power levels
User friendly LED control panel
Quiet operation

The TWIM 15 portable induction heater package includes:
Portable induction heater TWIM 15
Magnetic K type 400 mm temperature probe TWIM 15-3
Temperature resistant gloves TMBA G11
Instructions for use

Versatile
Because of the induction plate’s flat shape, a support yoke is not needed. This increases the type of components that can be heated on the plate and also reduces the number of required accessories.

Portable
Due to the medium frequency technology used and choice of materials, the heater is lightweight. Also, the built in handle makes it convenient to transport, and it can be stored easily.

Innovative heating
Utilizing smart construction and operating software, the heater creates a low temperature difference between the inner and outer ring of the bearing. This reduces the internal tensions generated due to excessive thermal expansion of the inner ring compared to the outer ring

Power regulation
Featuring different power settings, the TWIM 15 can heat sensitive components at a slower pace. Also, a non bearing power configuration is possible where most of the power is focused on the bore of the component.

Quiet
Using medium frequency technology to heat components does not generate noise. A LED indicates when the TWIM 15 is heating, even if you cannot hear it. In parallel, a cooling fan might be heard to help the heaters electronics to stay cool.

1) SKF does not recommend heating bearings capped with seals or shields above 80 °C (175 °F). However, if higher temperatures are necessary, please contact SKF. The heater is designed for maintenance operations where some cooling in between jobs is allowed.
2) Depending on the geometry of the bearing, maximum heating temperature and power availability.
