Choose Round Day Tanks when you have no time for downtime due to a leaky crucible. These workhorses can go for years before maintenance may be required. These furnaces are very efficient glass melters thanks to small external surface area, generous insulation, heat recuperation, tight construction, unique heating chamber design and large glass surface area exposed to the heat.
Round Day Tank models are lined with press bonded AZS. We have this material since 1999, and found it to hold up very well to thermal shock and corrosion. The first furnace liner we built from this material lasted for 13 years at Tulane University in New Orleans, LA. We expect 8-10+ year lifespans and have recorded 35% reduction in heat loss compared to our earlier rectangle models. Clients report higher glass quality as well, which can be attributed to a decrease in combustion volume and the absense of corners in the tank liner. Round Day Tank Furnace Spec Sheets
