Applications
Crystal Growth
- Industry leading reliability provides peace of mind during long crystal growth runs that can take several weeks
- Exceptional control resolution and stability facilitates precise temperature control with temperatures exceeding 2200° Celsius
- Mesta systems have been used with many materials including; Silicon Carbide, Aluminum Nitride, Gallium Nitride, Aluminum Garnet
Fiber Optics
- Mesta’s On-Demand auto tunings allows user to optimize furnace efficiency for each operating cycle
- Remote communications allow for logging of data for each specific heat run to help maximize production yields
Epitaxy (MOCVD & CVD)
- Air-cooling allows for low maintenance and high efficiency in high volume production facilities
- Mesta systems are widely used in the production of semiconductor materials
Advantages of Parallel Resonant Topology
Mesta parallel resonance topology aids in precise control and system efficiency, especially when compared with series resonance systems.
Fixed frequency PWM power control greatly enhances control stability and resolution.
Parallel resonance topology decreases the conductive losses between the inverter output and the load, which also allows for remote location of the Mesta power supply if needed.
