Dual chamber vacuum furnaces vs Single chamber vacuum furnaces – An energy perspective

On April 17-19 2024, TAV VACUUM FURNACES participated as a speaker at the 4th MCHTSE, Mediterranean Conference on Heat Treatment and Surface Engineering.

Our speech focused on the energy aspects of vacuum heat treatment, a subject towards which all of us within the industry need to pay attention for reducing the carbon emissions aiming at a zero net emissions future.

We have already analyzed the essential role that vacuum furnaces will play in this transition, with a focus on the optimization of energy consumption in our previous article; with this new presentation instead, we wanted to emphasize how selecting the right vacuum furnace configuration for specific processes may impact the energy required to perform such process. For doing so, we compared two different furnace designs, i.e. single chamber VS dual chamber vacuum furnaces, detailing all of the components energy consumption for a specific process.

As a sneak peek into our presentation, we will summarize below how the main features of the two vacuum furnaces design are affecting their energy performance.

Let’s start by introducing the protagonist of our comparison: a single chamber, graphite insulated vacuum furnace, model TAV H4, and a dual chamber furnace TAV DC4, both having useful volume 400-400-600mm / / 16”x16”x24” (WxHxD).
