Dual chamber furnaces are economical and consume less space compared to other types of heating furnaces. A dual chamber furnace has two heating chambers: high heat chamber for hardening and low heat chamber for tempering, drawing or annealing. Combination of two chambers allow immediate tempering or drawing after quenching without waiting for the hardening furnace to cool to the required lower temperature.

Depending on your preferred power source, you can choose a gas dual chamber furnace, electric dual chamber furnace or oil fired dual chamber furnace.

Some important parameters you must consider before purchasing a dual chamber furnace are:

1. Type of heat treating process
2. Temperature ranges required for your dual chamber furnace
3. Material and dimensions of the components
4. Requirement of the specific gas environment
5. Power consumption of the dual chamber furnace
