CORE SYSTEMS
Four industrial-furnace platforms
100% Hydrogen Bell-Type Annealing System
For annealing processes that require a controlled hydrogen atmosphere and managed thermal cycle.
View system
Bogie-Hearth Heat-Treatment Furnace
Batch heat treatment of large or heavy loads introduced on a movable bogie.
Pusher-Type Furnace
Loads advance through process zones at a defined pitch; a published application is heating and homogenising aluminium ingots.
Roller-Hearth Furnace
Products travel continuously through defined heating zones and, where required, cooling sections.
