Introduction

The simatherm IH 025 induction heater is designed for heating roller bearings and other ferritic, circular workpieces. The heat causes the workpiece to expand, which eliminates the need to use force during installation. A 90 °C (194 °F) temperature difference between the bearing and shaft is sufficient to enable easy installation. At an  ambient temperature of 20 °C (68 °F), the bearing must therefore be heated to 110 °C (230 °F).
1.1 Intended use
The IH 025 induction heater has been designed to heat roller bearings. Examples of acceptable workpieces include bushings, shrink rings, pulleys, rings, etc. The simatherm IH 025 portable induction heater is primarily intended for on-site repairs and roller bearing replacements by service and maintenance staff.
1.2 Principle of operation
The IH 025 generates a magnetic field in the medium frequency range (approx. 25 kHz), similar to an inductive hot plate. The magnetic field induces a voltage targeted on the inner ring of the workpiece. This creates eddy currents, which efficiently heat the workpiece. As the heat in the workpiece is generated by the current flow, all other parts of the induction heater remain cold. The heating process is based on the principle of eddy currents, so the workpieces to be heated should be composed of ferritic (= magnetic) metals. In cases of doubt, simply check the workpiece using the magnet of the temperature probe. This heating method patented by simatec enables fast, easy and energy-efficient heating of workpieces.

1.3 Distinguishing features
The distinguishing feature of the IH 025 VOLCANO induction heater is the fact that the workpiece can only be placed on the cone-shaped workpiece support for heating. The energy transfer is contact-free, and is generated via the medium- frequency coil situated below. The cone-shaped workpiece support creates an optimal magnetic field distribution in the rings of the roller bearing, thereby ensuring that heat is distributed homogenously. This design improves efficiency, resulting in lower power consumption and faster heating, which significantly reduces the costs of heating the bearings. This special technology allows the device to be very light weight and portable.
In addition, the device is fitted with predictive temperature control (PTC). For every heating process, the temperature increase curve of the workpiece/ oller bearing is measured constantly, thereby optimising the heating performance. This ensures that the target temperature is achieved quickly without overheating the roller bearing.

Description

The operation of the heater is controlled by the internal electronics in two modes. The operator can either select the desired temperature in TEMP MODE or set the length of time for heating in TIME MODE. The power level can be adjusted in steps of 10% for slow heating of sensitive workpieces (for example, bearings with C1 or C2 clearance).
2.1 Components
The simatherm IH 025 VOLCANO induction heater is comprised of a portable housing with integrated operating electronics and cone-shaped workpiece support. A temperature probe can be attached for measuring and monitoring the temperature of the workpiece. The mains cable is enclosed separately, as are protective gloves for safe handling of hot workpieces. All of the equipment can be stored in a practical carrying case.

Preparation for use

• Place the device horizontally on a stable, non-metallic surface.
• Ensure that the device’s ventilation slots are free at all times and that it can suck in cold air on the ground.
• Connect the mains plug to a suitable power supply.
• The roller bearing to be heated is placed horizontally in the centre of the IH 025 VOLCANO induction heater’s step-shaped support cone.
• If you are going to operate the device in TEMP MODE, connect the temperature probe with the helix cable to the left side of the device. Make sure the polarity of the plug is correct.
• Use the holding magnets in the measuring head of the temperature probe as a quick and easy way of checking whether the workpiece is made of ferritic metal (= magnetic) and therefore can be heated optimally using the simatherm IH 025 induction heater.
• The magnetic measuring head of the temperature probe is placed on the inner ring of the roller bearing or the innermost point of the ring. The temperature probe is only used in TEMP MODE. When heating a workpiece in TIME MODE, the probe is not required and does not need to be connected.

Operation

4.1 Function of display A The main display shows the selected heating time or heating temperature.

4.3 Temperature mode

• If the main display shows ‘t’, press MODE to select TEMP MODE. The main display shows °C or °F in TEMP MODE.
• The selected temperature is shown on the main display. The default temperature for bearings is 110 °C (230 °F). If a different temperature is desired, press UP or DOWN to adjust the temperature in steps of 1°C (2 °F).
• It may be desirable to heat bearings to temperatures above 110 °C (230 °F) for increased mounting time. To determine the maximum permitted temperature, consult the specifications of the bearing manufacturer. Always ensure the bearing does not lock due to an excessive expansion of the inner ring compared to the outer ring. See section 4.8.
• All Spherical Roller Bearings (SRBs) are subjected to a special heat treat-ment. These bearings can be operated at temperatures as high as 200 °C (392 °F). Heating these bearings above 110 °C (230 °F) will not cause any damage as long as the bearing is still able to rotate. For other bearings, a temperature of 125 °C (257 °F) must not be exceeded unless otherwise specified.
• Press POWER to select the power level. Use the guidelines in section 4.8 to determine the correct power setting.
• Press START/STOP to start the heater. The main display shows the current temperature of the workpiece.
• When the selected temperature has been reached, the heater demagnetises the workpiece, switches off, and generates an acoustic signal for 10 seconds or until START/STOP is pressed.
• Press START/STOP to stop the heater.
• Always wear protective gloves and other appropriate protective equipment when removing the hot workpiece. NB: Risk of burning. The workpiece may also be removed using suitable handling equipment.
• If the workpiece remains on the heater, the heater will start again when the temperature of the workpiece drops 10°C (18°F). Press START/STOP to stop the heater and demagnetise the workpiece.
• The device is now ready to heat another workpiece with the same settings.

4.4 Time mode

• If the main display shows °C or °F, press MODE to select TIME MODE. The main display shows ‘t’ in TIME MODE.
• Press UP or DOWN to adjust the time in steps of 0.1 minute.
• Press POWER to select the power level. Use the guidelines in section 4.8 to determine the correct power setting.
• Press START/STOP to start the heater. The main display shows the time that remains.
• When the time has elapsed, the heater demagnetises the workpiece, switches off, and generates an acoustic signal for 10 seconds.
• Press START/STOP to turn the induction heater off.
• Always wear protective gloves and other appropriate protective equipment when removing the hot workpiece. NB: Risk of burning. The workpiece may also be removed using suitable handling equipment.
• Remove the workpiece using proper handling equipment.
• The device is now ready to heat the next workpiece with the same settings.

4.5 Temperature measurement
When the heater is not operating, the temperature of the workpiece can be measured by pressing MODE and START/STOP at the same time. The LED on the START/STOP button flashes during temperature measurement. Press START/STOP to cancel temperature measurement.
4.6 Change of temperature unit
Press MODE and UP at the same time to switch between °C and °F. The temperature unit setting remains the same even after disconnection from mains power.
4.7 Demagnetisation
According to the „eddy current principle“, the work piece is automatically demagnetised at the end of the heating cycle.
4.8 Power level selection
When heating bearings with the IH 025 Volcano, it is important that bearings with small internal clearance or slight preload are heated slowly. Slow heating ensures that the bearing expands slowly, thereby preventing damage to the bearing. In addition, it is possible that the ferrite cage and seals could be heated more quickly than the inner-ring, due to their low mass. The shape, weight, size, and internal clearances all affect the amount of time required to heat a bearing. The large variety of bearing types precludes the possibility of providing a specific power level setting for each type. Instead, the following guidelines are provided:
For sensitive bearings (little internal clearance) the power must be reduced.

• Max. 20% for small bearings (positioned around the tip of the cone)
• Max. 40% for medium-sized bearings (positioned in the centre of the cone)
• Max. 60% for large bearings (positioned at the bottom of the cone)
  The set power output can be reduced by half, if required.

For bearings with a steel cage or with seals, the power must be reduced. The table below shows what power level to be selected.

If the bearings are sealed with gaskets on one side only, they must be placed on the device with the seal facing upwards. In this arrangement, the power level of 100% can be selected.

Safety features

The IH 025 device is equipped with the following safety features:

• Power switch
• Internal safety fuse for power electronics
• Automatic overheating protection for the circuit breaker
• Automatic current control for intermediate circuit and coil electricity
• Automatic detection and power reduction if no workpiece is in place for heating.
• In the TEMP MODE the heater will switch off if the temperature probe does not register a temperature increase of 1 °C every 20 seconds. To increase the interval to 50 seconds, press MODE and DOWN at the same time.

Electromagnetic field and personal safety

During the heating function, the IH 025 unit generates a maximum magnetic flux density of less than 5.7 µT at a distance of half a meter away. The device is therefore within the range that applies to the household sector for induction cooktops. Modern pacemakers are protected from such interference. Nevertheless, the manufacturers recommend that those using pacemakers remain a minimum distance of 40 cm from the induction heater. People with cardiac pacemakers should check with their doctor about possible disrupting effects.

Troubleshooting

A system fault will be indicated by an acoustic signal and one of the following fault codes on the main display:

(or 1 °C every 50 seconds)

| Check the temperature probe connec- tion. If the connection is OK, select the 50 second interval as described in

section 5 or operate the heater in TIME MODE.

E06 E| Temperature probe not con- nected (or defective)| Check the temperature probe.
