One-Piece Exchanger
August 1, 2002
Dunkirk's new Quantum 90-200 boiler features a cast-aluminum one-piece heat exchanger, which eliminates leaks that can occur due to section interface with sectional heat exchangers. The cast-aluminum also transfers heat three times faster than conventional cast-iron and provides gains in heat-up speed, operating efficiency and thermal storage. In addition the Q90-200 provides a remarkable 90 percent AFUE efficiency.
