Tool rooms rarely have just one type of heat treating job. One day you may be hardening tool steel, the next you’re tempering a small batch, annealing a fixture, or stress relieving a component.
A dual chamber furnace can provide the flexibility to handle different processes, temperatures, and load sizes in one system. With independently controlled chambers, two different heat treatment cycles can run at the same time without requiring separate furnace footprints.
Our latest article breaks down how dual chamber furnaces work, common tool room applications, what to look for when selecting one, and how chamber size, temperature uniformity, controls, and atmosphere can affect your results.

Understand how dual chamber furnaces support tool room heat treating, including hardening, tempering, annealing, furnace selection, controls, sizing, and maintenance.

As we continue to grow, we are investing in the equipment and in-house capabilities needed to support that growth.

Our laser table allows us to produce precision sheet-metal components for our furnace and oven builds, giving us greater control over accuracy, fit, quality and production timing.

This Lucifer logo is a simple demonstration, but the same capability supports the industrial heat-treating systems we build every day here in Pennsylvania.

There’s something pretty cool about seeing a furnace come together on the shop floor.
This 44GT-R36 Gas-Tight Atmosphere Oven is currently in production, with a 24" x 24" x 36" chamber. It’s always fun to see the pieces come together and watch another Lucifer Furnace take shape.
From our shop to yours, we’re proud to build these right here in the USA.

Look what we found!
This old dual chamber furnace is another little piece of Lucifer Furnaces history. We love coming across photos like this and getting a glimpse at some of the equipment we were building years ago.
The designs may have evolved over the years, but it’s pretty fun to see how much of our history is still sitting in these old photos.

Another little piece of Lucifer Furnaces history.
This furnace detail print dates all the way back to 1951. The drawings may look a little different from what we use today, but it’s pretty cool to see the engineering and craftsmanship that went into our furnaces more than 75 years ago.
Some things change. Building furnaces to last doesn’t.

A little more Lucifer Furnaces history.
These old photos give us a chance to look back at some of the people who helped build the company over the years.

If you recognize either of these familiar faces, let us know!

What happens when a standard oven doesn’t meet your process requirements?
Lucifer Furnaces recently built and shipped a custom controlled-atmosphere oven designed for a specific application where atmosphere control and precise temperature performance matter.

A little blast from the past!
We found a couple of old Lucifer Furnaces magazine ads and couldn’t resist sharing them. The look may have changed since the 1940’s but some things haven’t—our love of building dependable heat-treating equipment has been around for a long time.

Which one is your favorite?
