The perfect solution for every heating task
10/22/2009What do solar cells based on silicon wafers and glasses of chocolate spread have in common? At the production of both products induction heating plays an important role. Silicon mono-crystals, which are the base of solar cells with the highest efficiency, are produced by using the so called zone floating method - a process which would be unthinkable without induction heating. And, the sealing of the glass of chocolate spread is achieved by induction too. These two examples show how broad the range of applications for induction heating is. It ranges from conventional applications like hardening, annealing and soldering to high-tech applications such as crystal growing. But all of these application fields have one thing in common: HÜTTINGER power supplies for induction heating are the heart of the required heating processes.
At the EPM 2009 (6th International Conference on Electromagnetic Processing of Materials), which took place from October 20th to October 23rd 2009 in Dresden, Germany, HÜTTINGER informed about its extensive product range of medium and high frequency power supplies and showed visitors that HÜTTINGER power supplies are the perfect solution for every heating task.
The power supplies of the TruHeat MF Series 3000 / 5000 / 7000 are powerful and can be used for versatile applications. Available with an output power of 10 to 250 kilowatts over a frequency range of 3 to 100 kilohertz, they are suitable for conventional applications as well as for high-tech applications. Among its range of applications are epitaxy and crystal growing, hardening, melting, soldering and annealing processes. The remarkable thing about the TruHeat MF Series 3000 / 5000 / 7000: The high reliability of these power supplies assures a high productivity at constant process results. Moreover, the TruHeat MF Series 3000 has a very compact design and provides the highest power density on the market: These power supplies are power packs which can be easily integrated into existing systems or facilities due to their small dimensions.
The power supplies of the TruHeat HF Series are also very versatile: They are suitable for crystal growing, zone floating, inductive plasma and glass melting and can also be used for heat treatment and soldering of least units.
The TruHeat HF Series 1000 / 3000 / 5000 consists of high frequency power supplies with an output power of 5 and 10 kilowatts. These power supplies are characterized by a compact design accompanied by high power and a broad frequency range. Due to its high efficiency of more than 90 percent the TruHeat HF Series 1000 / 3000 / 5000 contributes to the profitability of the operator's production. This assures - thanks to short heating times and precise energy delivery - a higher productivity even at the overall result. In addition the power supplies provide all established interfaces making simple system integration possible.
The TruHeat HF Series 7000 possesses an approved tube technology and generates high power at high frequencies. The TruHeat HF Series 7000 products are available with an output power range from 10 to 500 kilowatts. Frequencies range from 100 to 800 kilohertz and from 1000 to 3000 kilohertz. For decades, power supplies of the TruHeat HF Series 7000 have been proving their reliability in the market. Therefore they allow optimum results even with critical processes which require long-term stability and low breakdown rates. Such a critical process is the so called zone floating method which permits the creation of ultra-pure single crystals. This process requires a high and constant process heat. As the functional and regulation parameters of the TruHeat HF Series 7000 are very stable, even during permanent operation over several days these induction power supplies allow precise and reproducible process results even with the zone floating method.
HÜTTINGER not only offers the right power supply for every heating task, but also provides an important service for its customers: At its in-house applications lab the HÜTTINGER induction specialists support customers in achieving their heating task. As a result of extensive consultancy and long term expertise, an appropriate solution is always found. The customer then gets a solution which fits its process perfectly. Moreover he saves valuable time which is a significant competitive edge.
