Since heat is the temperature difference between the supply air cupola-style cupola foundation of our company in 1988 on the development, through our many years of manufacturing experience in debugging and user feedback, optimized to improve the design, adjusted design, equipment operation and more stable, reliable, improve the foundry overall efficiency, adapt to the requirements of domestic casting furnace. Since hot air cupola for itself is the only air heat exchange for technical and economic indicators of high, excellent performance, smelting low loss, low emission, low pollution, easy operation, long life, low investment and quick high-quality equipment, it is currently producing high-quality, high-grade German export thin-walled castings and preferred high-grade iron furnace.

Features:
1, the heat exchanger using patented technology, the lower flange using stamping flange, effectively extending the life of the heat exchanger. The factory of the heat exchanger multi-speed load test to ensure that pre-qualified rate of 100%.
2, the use of external air, to avoid unforeseen circumstances iron slag poured into the bellows.
3, cupola coke than the average 10% - 20%.
