Technology behind Green Furnace
- Voltage boosted (up to 5250V) and stretching improved for fastest power pickup and quick melting
- Lowest electrical loss of 18.5% achieved by restriction of copper current density and layout manipulations
- Low peak power requirement and fastest melt time i.e. 400T production
from 20T furnace, 160T production from 10T furnace on ingot - Sustained power factor without the need for capacitor switching (as seen in series design)
- Most robust R&D ecosystem resulting in a multitude of new launches, models and up coming technologies

Upcoming technologies
- Variable Power Inverter (impact: 10 to 15 kWh/t)
- Zero Voltage Drop Design (impact: 8kWh/t)
- Generation 4 Blast Resistant easy maintenance Crucible
- Online self rectifying furnace eliminating need for commissioning engineer. Remote servicing only.
Digital Module
- Monitoring of temperature and pressure in critical points aids preventive maintenance
- Early warning system provides ample time for maintenance before breakdown
- Real time monitoring of HT & LT parameters
- LT & HT graphs and trends allow for post production analysis and addressing
of operational issues to improve productivity & energy consumption
Special add on features
Nano Cable
Compact layout reduces copper losses and improves system efficiency. Reduced size of water cooled cables further reduces copper losses. Reduced size of water cooled cable also lowers
voltage drop between panel and coil and leads to faster power pickup and quicker meltin
Pollution control hood
Our next generation pollution control hood ensures complete cover during melting, as well as de slagging and tapping. Ladle fumes are also extracted. Two way tiltable hood ensures smooth charging and allows little room for fumes to escape due to lower pressure loss and less false air. Low emissions and low energy consumption together makes our furnaces truly Green
Low Power Efficiency System (LPE)
Power Factor of above 92% from 0% to 70% of power range(including sintering heat) and above 98% from 70% to 100% power range. Results in fast melting and lower energy consumption during low power operations including sintering, holding, etc
Megatherm is differentiated from other manufacturers by its product innovation and continuous R&D. Over the years Megatherm has paved the way for most major design changes and additions to induction technologies which was later adopted by the industry. Some examples include multi zoned coils, use of PLC in IMF, low frequency technology for energy consumption, OFWF converter transformer, parallel inverter and many more. Our research is focused on energy consumption & productivity and our systems are incorporated with the best contemporary technologies that ensure optimum utility and comprehensive productivity. We promise to keep you two steps ahead and future proof.
