Batch furnaces
Bogie hearth furnace
Up to 1400 °CA bogie hearth furnace is a chamber furnace with a movable hearth. The load sits on a trolley (the bogie) that rolls out for loading and rolls back in, so very heavy or awkward parts can be handled…

Chamber (box) furnace
Up to 1600 °CChamber furnaces are the general-purpose workhorse of heat treatment. Material is loaded into the chamber, heated through its cycle and unloaded, which suits low to medium volumes and custom-sized parts.

Pit type furnace
600 to 1200 °CPit furnaces stand vertically with the opening at or just above floor level, and are made for work from very small to very large. They are available with or without a retort, in custom dimensions, electric or gas-fired.

High-temperature pit furnace
Up to 1200 °CThis is a sealed retort design: a vertical cylinder with a positive seal on top that keeps both heat and atmosphere inside during the cycle. The charge sits in a retort, which is heated from outside by electric elements or gas.
