What is a Top Hat furnace? And why would I want one?
Top Hat vs Bottom Load Furnaces
We all know that with the familiar “elevator” furnaces, aka “bottom loaders”, the load platform or kiln car is raised into the furnace body. In the “top hat” design, the opposite occurs. The furnace body is lowered over the platform or kiln car.
A frequently expressed concern is that because the furnace body is in motion, the insulation – and worse, the elements – will be subject to damage from vibration. Not so! This can be prevented with good design of the lift system.
Ok, but is there any reason to prefer the “top hat” over a bottom loader? There are several: application requirements, ergonomics, and maintenance considerations.
Deltech manufactures both top hat and bottom load electric lab and production scale furnaces, and all are well designed. The choice is yours; we hope you find this information helpful in finding the furnace that will fit your need. Or contact us so that we can work with you on designing a unit with optimal features for your process.
