We are offering induction heater. Model ehs series induction heaters are designed for mounting of bearings or any other ring shape part like pinion, bearing races, lybringth, gears, couplings, etc by expanding through induction heating and shrunk fit on the axles.many bearings are pre-lubricated and protected by shields or rubber seals. Others have brass or copper cages. Some have unusually small clearance. All types can be heated by easy~heat (s) induction heaters. Made from impact resistant strong, scratch resistant body of fibre glass coated with special heat resistant pu harel coating. The horizontal yoke and bearing to be heated are placed across vertical supports are ground machined to keep energy losses very low. The entire magnetic conductors made from crgo laminations. Ehs series models incorporate the latest microprocessor controller with memory backup and its unique feature is the recipe programming. The user can store different recipe programs for operating parameters like heating time & temperature for the frequently shrunk fitting jobs like bearings, races, pinions, couplings etc. The heater can operate in two different modes ie, temperature mode or time mode ,this control give digital readout of the bearing temperature in temperature mode or time mode shows heating time in countdown manner. Both temperature and timer readouts simultaneously displayed. Ehs series models incorporates an auto ramping cycle to avoid current surges due to sudden switching of full power and built in demagnetizing unit, to solve the problems of attracting microscopic iron particles caused by residual magnetism. This cycle is automatically performed at the end of each heating cycle. Also an audio alarm after heating and demagnetizing cycle is completely over with auto cutoff facility. The induction heater equipped with height adjustable type bearing resting devices which is capable to control the heating of bearings uniformly.

The Induction heater consists of a transformer with primary connected to the 230 V AC supply and in the secondary there are no windings but a BEARING, PULLEY, COUPLING , GEAR ETC.

Induction Heater Model PIH 2004 V (25 - 40 KVA) specialy designed for mounting of bearings gears pinions and other components in horizontal position and suitable for job bore dia 150 mm to 600 mm and outer dia. 1000 mm width 600 mm weight max. 1600 kg

Induction heater design have utilized the eddy current induction principle like a transformers - its core and windings can be seen as the primary side, but the work piece acts as a short-circuited secondary winding, which heats up rapidly due to its great electrical resistance. This phenomenon allows the induction heater to control the heating by continuously monitoring the work piece temperature and adjusting its own heating power during the process. Hence results in even heating of only the inner bearing ring but the heater itself remains cool and safe to handle

Minitronix, a partnership company established in 1975 became Minitronix Machines Pvt. Ltd. in 2009. We specialise in manufacturing Mains & Medium Frequency Induction Heating Machines for shrink fitting applications. We design and implement each machine to suit customer’s exact requirement which includes automation required for these machines. We have supplied 100 plus custom made machines in last 12 years.

nline induction wire preheater is used to heat the wire prior to extrusion coating processing etc. ideally suitable for Cable and Wire Industry. It improves the adhesive coating of Insulating material on conductor as the temperature of the conductor remains same throughput the run and the heat flow is even through out the wire to assure that no cold patches occur at the any line speed hence avoid the wastage of costly raw material gives high quality and product and higher product speed. It works on electrical inductive resistance heating principle assure no current flow to other wire line equipment. The heat on the wire is applied evenly at all the operating should regardless of wire diameter. A sold state thyristorised control with line speed Encoder feedback provides correct secondary voltage as per desired setting. It also eliminates wire burn out during stoppage. Line Voltmeter Power ON Heating on indication is provided with Auto Manual selection and heating potentiometer for easy operation and quicker setting. Current limit circuit protects the Preheated Coil from overloading. The entire unit is self-contented Powder coated with glass window cabinet and doesn't require any foundation footing

For frequent dismounting of cylindrical roller bearings The adjustable induction heaters EAZ 80/130 and EAZ 130/170 are used for frequent dismounting of cylindrical bearing inner rings. Where inner rings are removed infrequently, aluminium heating rings, TMBR series, are also available. For larger cylindrical inner rings normally found in steel mill applications, SKF can supply special EAZ induction heaters. Features and benefits Covers most cylindrical bearings 65 to 130 mm (2.5 to 5.1 in.) bore diameter Wide range of power supplies Avoids shaft and bearing inner ring damage Fast and reliable bearing removal Up to n6 interference fit  

We are offering a wide range of Induction Bearing Heaters to our clients. These heaters are based on the principle of heating an electrically conductive material without directly being in contact with it. While heating any material by these heaters the fear of contamination is almost lost. Due to its unique heating abilities, these heaters are used in some specific types of heating purposes in the industry.

Many rolling bearings and other rotationally symmetric steel parts are tightly fitted onto the shaft. Larger parts in particular, can be fitted more easily if they are pre-heated (rolling bearings up to a maximum of 120 °C). Energy efficient, clean and environmentally friendly (no oil, and therefore no disposal cost),Demagnetised and stress-relieved work pieces,Highly adaptable as several different ledges can be used with the apparatus.
