The Stack melt zone may be operated independently for melting large scrap utilizing normally lost flue gases to assist in the efficient and economic melting of returns. The furnace may also be used in the conventional reverberatory mode utilizing the wet bath zone for preheating and melting of sow and ingot bundles on the pre-heat hearth and proportional firing to maintain precise process temperature control in reverb for consistent high quality castings. For maximum capability both zones may be operated simultaneously. The furnace may also be furnished with the stack portion and a separately controlled hold zone only. The stack melter's space-efficient design is excellent for areas with space limitations and frequent alloy changes. It comes in standard melting ranges from 1000 lbs./hour up to 5,000 lbs./hr, with an estimated fuel consumption production as low as 1,000 BTU/lb.

Now available in modular form allowing retrofit of stack to existing furnace.
