EcoMelt™ Financials

High yields and long furnace life are necessities for a float facility to reach full profit potential. Stewart Engineers achieves these objectives through:

EcoMelt furnaces can attain 20-year melting campaigns. Long campaigns between rebuilds provide the highest return on investment. Lost sales revenue during a rebuild exceeds rebuild capital expenditures.

Stewart Engineers specializes in achieving high yields by utilizing a combination of EcoMelt™, StewartFloat®, and Acuracoat® technology. Raising yields by 1% results in nearly $1M additional sales revenue per year. Our detailed operational and maintenance training will serve as the foundation to ensure superior furnace performance, boost yields, and lengthen furnace life.
