1.3 Distinguishing features

• High efficiency
With its advanced power electronic and induction coils design, the TIH L and its
resulting low power consumption of 20kVA, can heat up bearing weighing up to 1
200 kg (2 600 lbs) typically requiring 40kVA input power. Representing 50 % energy
savings.
• Versatile heater design: two bearing/workpiece heating positions
TIH L heaters are designed for applications where the bearing is to be heated vertically
to be mounted on an horizontal shaft and applications where the bearing or workpiece
is to be heated horizontally to be mounted on a vertical shaft. See the illustrations at
the beginning of this manual.
The workpiece can therefore be located either over the (sliding) yoke or over the
outermost inductive coil. Bearing should preferably be heated over the (sliding) yoke
while heavy workpiece can be heated over the inductive coil (see chapter 5.8).
• Remote control panel
To improve the ease of use and to help reduce the risk of contact with the hot bearing
during operation, the TIH L heater is supplied with a remote control panel which can
be detached from the heater.
• Sliding yoke
To facilitate the handling of the yoke while placing the bearing around it or around
the induction coil, the TIH L is fitted with a sliding arrangement for the yoke. See the
illustrations at the beginning of this manual.
• Bearing supports
To support large workpiece when positioned horizontally around the induction coil, the
TIH L induction heater is provided with two bearing supports. See the illustrations at
the beginning of this manual.

2. Description

The operation of the heater is controlled by the internal electronics in either of two
modes. The operator can either select the desired temperature of the bearing in TEMP
MODE or set the length of time that the bearing will be heated in TIME MODE. The power
level can be adjusted to 100 % or 50 % for slower heating of sensitive workpieces (for
example, bearings with C1 or C2 clearance).

2.1 Components

The TIH L induction heater contains a U-shaped iron core with two induction coils
surrounding the respectively vertical supports. Bearing supports are delivered to be
mounted on the heater. A detachable remote control panel is included. The remote control
electronics and the internal electronics, control the operation of the heater. A sliding yoke
allows the workpiece to be placed onto the heater. A temperature probe is included with
the heater. Heat-resistant gloves are also included.
