S-Heat is the foundation of the LJ Induction’s heating system. Each S-Heat induction heater included a power machine, capacitors, and a matching unit if necessary. All S-Heat induction coils are customized and designed to deliver heat to workpieces, which can best suit your specific heating applications and works.

A heat exchanger which generates an electric current or the power it provides may cause an electric shock by forcing heat in from the air or the atmosphere. A radiated alternating magnetic field envelopes an electrically conducting material. We manufacture induction heating equipment in the range of 1hz – 1Hz power supply and metal furnaces. These induction-powered systems have been engineered to provide an optimal solution for several different applications ranging in size from forging to welding, shrink fitting to melting, and hardening to annealing.

Range:40kHz

The thyristor rectifiers and bridge inverters used in S-Heat’s high-frequency induction systems feature parallel compensation. Single-phase and three-phase diode rectifiers and rugged IGBT transistors of the serial-compensated systems are designed to be virtually short-circuit-proof.

As the most popular induction heating machine in LJ Induction, high-frequency system machines have been used in almost every heating application. Talk to us, maybe this machine can help your heating job!

Range:1-20kHz

S-Heat’s medium frequency systems are parallel and serial-compensated. In the first case, the rectifiers are thyristors and diodes in the latter. With both versions, IGBT transistors are virtually short-circuited proof. Low-power serial-compensated systems support a wide spectrum of coils with hand-held transformers (connected via flexible power cables).

The medium frequency induction heating machines are widely used in forging and melting, and heat treatment.

Range:100kHz to 1.1mHz

In addition to parallel- and serial-compensated converters, S-Heat offers high-frequency systems. Fast IGBT technology is used in parallel-compensated high-frequency systems, allowing them to run up to 100 kHz to 1.1 MHz. High-frequency S-Heat systems are equipped with IGBT transistors and diode rectifiers.

The ultrahigh-frequency induction heating machines can be used in welding, surface heat treatment, and annealing. Because of its very high frequency, it can heat to very high temperatures in a very short time to the smallest surface depth, for example, surface heating under 1.5mm.

Dual frequency :

In order to switch between two various frequency ranges using the same generator, a power supply with dual-frequency capabilities (DF) is required. One of these types is ideal for companies that wish to buy only one generator but have multiple applications that require different frequency ranges. Depending on the process, it may be necessary to operate at a range of 8-40 kHz and 140-350 kHz .

When we heat-treating some complex shapes, dual-frequency is necessary to get the best hardening result.

Best for every heating task

Wide range:

Parallel and serial compensated converters are available for virtually any induction heating application. 5 to 2000 kW and 0.3 to 350 kHz are the power ratings and frequencies.

Maximum productivity:

During the heating process, automatic control maintains optimal output power. In addition to manual regulation, continuous regulation can also be carried out via standard external controls. Equipment uptime and output are increased due to easy operation, small footprints, and proven reliability.

Unrivaled efficiency:

With a constant power factor of 0.95 regardless of power level and an efficiency factor of 85-87%, this diode rectifier is a good choice.

Operational flexibility:

With S-Heat’s variety of systems and technical features, you can select the perfect solution for your needs. There are Thyristor, IGBT, and PowerMOS inverters and a variety of rectifiers and matching and control systems, such as automatic load matching.

Improved quality:

A modern induction heating system, S-Heat provides precise, no-contact, controllable heat, reproducible temperatures, and ramp-up and dwell times to improve quality. Scrap reduction and rework also reduce costs as a result of better quality.
