The Lindberg/MPH Holimesy furnace design incorporates the most revolutionary concept of insulation in both the metal containment area and the roof (or element chamber area) in a completely enclosed unit. The result is the most energy-efficient aluminum holding furnace available. Typical energy costs are reduced by 80-90% over older furnace styles. Tests have shown an average Lindberg/MPH Holimesy furnace in production used 5 KW/hr. for a cost of .25 per hour!

LOW METAL LOSS

The Lindberg/MPH Holimesy furnace is totally enclosed, which, along with uniform operating temperatures and special ceramic lining plates almost completely eliminates oxide and sludge formation in the bath. Therefore, little or no metal loss and maximum metal quality.

EASE OF MAINTENANCE

Since the metal losses are so low and oxide buildup on the heating chamber walls is almost non-existent, it is only necessary to clean the main chambers once a week. This task generally takes about 10 minutes. Heating elements are long lasting but in the event of the need to replace one, it is a relatively simple low-cost operation.

IMPROVED WORKING CONDITIONS

In most aluminum operations, the furnace shell temperature does not exceed 90° F. The only molten metal surface area exposed to the atmosphere is the ladling well, keeping radiated heat to a minimum. Operating conditions are much cooler than with other types of furnaces.

NON-WETTING REFRACTORY

Special ceramic plates, non-wettable to aluminum, are employed in the metal contact areas. These highly insulating plates, joined by a patented interlocking construction, are backed up with other highly insulating materials to form a tight, enclosed unit with minimal heat loss.
