Application
Vacuum pumps for heat treatment and vacuum furnaces
In heat treatment in a vacuum furnace, metal parts are heated, held and cooled without air – for hardening, tempering, annealing, carburising or nitriding. The vacuum removes the oxygen from the furnace atmosphere: according to Leybold, the air-free furnace atmosphere prevents oxidation; Pfeiffer Vacuum names an oxygen-free atmosphere and uniform heating. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 359 models from 5 manufacturers.

In short
Heat treatment and vacuum furnaces: the key facts
- Furnace atmosphereAccording to Leybold, the air-free furnace atmosphere prevents oxidation; Busch names a low-oxygen furnace atmosphere, for example in case hardening, Edwards an oxygen-free environment.
- TemperaturesFor the hot zone, Busch names usually 1,200 °C, and above 2,000 °C for special processes. Depending on the process, Pfeiffer Vacuum names from 150–650 °C for tempering up to 600–1,300 °C for vacuum heat treatment.
- Pressure rangesPfeiffer Vacuum names 10 to 10⁻³ hPa for tempering, about 10⁻³ hPa for hardening, 1 to 10⁻² hPa for low-pressure carburising and about 10⁻² to 10⁻³ hPa for plasma nitriding.
- Series by processLeybold assigns its own series to the processes: DRYVAC and SOGEVAC for nitriding and hardening, DRYVAC with RUVAC WH/WSU and SCREWLINE for carburising, SOGEVAC and TRIVAC with RUVAC for tempering.
Operating principle
How it works: Heat treatment and vacuum furnaces
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- EvacuationAfter loading, the furnace is pumped down before the heating starts. According to Leybold, the furnace atmosphere thus remains air-free and the batch does not oxidise.
- HeatingThe batch is brought to process temperature and held there – for the hot zone, Busch names usually 1,200 °C. In carburising or nitriding, process gas is supplied at this stage; for low-pressure carburising Pfeiffer Vacuum names 1 to 10⁻² hPa at 900–1,050 °C.
- CoolingIn vacuum hardening, according to Leybold, rapid quenching follows; in tempering or annealing, the batch cools in a controlled way. The furnace is then vented and unloaded.
Vacuum and sizing
Heat treatment and vacuum furnaces: how much vacuum is needed
What the manufacturers say about pressure, pumping speed and sizing.
Which vacuum
Pfeiffer Vacuum names a pressure range for each process: tempering 10 to 10⁻³ hPa, normalising 10⁻¹ to 10⁻² hPa, low-pressure carburising 1 to 10⁻² hPa, plasma nitriding about 10⁻² to 10⁻³ hPa, hardening about 10⁻³ hPa, vacuum heat treatment 10⁻² to 10⁻⁵ hPa.
Gas load and condensate
For vacuum and plasma nitriding, Leybold points out a high gas load around the clock and names SOGEVAC and DRYVAC for this. In vacuum carburising, carbon-containing by-products condense easily; here Leybold names DRYVAC with RUVAC WH/WSU and SCREWLINE.
Temperatures
For the hot zone, Busch names usually 1,200 °C, and above 2,000 °C for special processes. Pfeiffer Vacuum names 150–650 °C for tempering, 800–1,000 °C for hardening, 900–1,050 °C for low-pressure carburising and 600–1,300 °C for vacuum heat treatment.
Which pumps
Leybold names SOGEVAC, TRIVAC, RUVAC, DRYVAC and SCREWLINE as well as the VARODRY family; Edwards rotary vane and dry screw vacuum pumps as well as EH, Stokes, GV and E2S; Atlas Copco DWS and GLS, for industrial furnaces GVD; Busch R5, MINK, COBRA and PANDA/PUMA; Pfeiffer Vacuum ACP, DuoVane, HiLobe, HiScroll and UnoLine Plus.

Heat treatment and vacuum furnaces: where the manufacturers name it
The manufacturers list these uses on their own pages.
Metallurgy and heat treatment
Busch, Edwards, Leybold and Pfeiffer Vacuum list heat treatment under metallurgy: hardening, tempering, annealing, carburising and nitriding in the vacuum furnace – according to Leybold, in an air-free atmosphere that prevents oxidation.
Automotive and transport
For automotive and transport, Busch names the low-oxygen furnace atmosphere, for example in case hardening, with R5, MINK, COBRA and PANDA/PUMA; Pfeiffer Vacuum also lists heat treatment in this industry.
Semiconductors, electronics and displays
Pfeiffer Vacuum also lists heat treatment under semiconductors, electronics and displays, without describing it in more detail there.
Frequently asked questions
Heat treatment and vacuum furnaces: frequently asked questions
How does heat treatment in a vacuum furnace work?
After loading, the furnace is evacuated, then the batch is heated, held and cooled. According to Leybold, the air-free furnace atmosphere prevents oxidation; Pfeiffer Vacuum names an oxygen-free atmosphere and uniform heating. Busch describes the process as changing the material properties in a vacuum furnace at high temperature – usually 1,200 °C in the hot zone.
How much vacuum does a vacuum furnace need?
That depends on the process. Pfeiffer Vacuum names 10 to 10⁻³ hPa for tempering, 10⁻¹ to 10⁻² hPa for normalising, 1 to 10⁻² hPa for low-pressure carburising, about 10⁻² to 10⁻³ hPa for plasma nitriding, about 10⁻³ hPa for hardening and 10⁻² to 10⁻⁵ hPa for vacuum heat treatment.
Which vacuum pump for heat treatment?
Leybold names SOGEVAC, TRIVAC, RUVAC, DRYVAC and SCREWLINE as well as the VARODRY family. Edwards names rotary vane and dry screw vacuum pumps as well as EH, Stokes, GV and E2S, and for vacuum furnaces nXRi and E2S. Atlas Copco names DWS and GLS, for industrial furnaces GVD and for plasma processes DWS VSD+. Busch names R5, MINK, COBRA and PANDA/PUMA, Pfeiffer Vacuum ACP, DuoVane, HiLobe, HiScroll and UnoLine Plus, and for annealing also A4, TORRI and COBRA BC/DS.
Oil-free or oil-lubricated for vacuum furnaces?
The manufacturers name both types. Edwards lists rotary vane and dry screw vacuum pumps, Atlas Copco the oil-lubricated GVD and GLS as well as the dry screw vacuum pumps DWS. Leybold names SOGEVAC and TRIVAC alongside the dry DRYVAC and SCREWLINE; for vacuum carburising, in which carbon-containing by-products condense easily, Leybold names DRYVAC with RUVAC WH/WSU and SCREWLINE.
Which vacuum pump for nitriding and plasma nitriding?
For vacuum and plasma nitriding, Leybold names SOGEVAC and DRYVAC and points out the high gas load around the clock; the process produces a nitride layer. For plasma nitriding Pfeiffer Vacuum names about 10⁻² to 10⁻³ hPa – the vacuum makes the plasma possible. Edwards lists EXS for nitriding and plasma nitriding, Busch COBRA and PANDA/PUMA for nitriding and Atlas Copco DWS VSD+ for plasma processes, each without further description.
Which vacuum pump for carburising?
For vacuum carburising, Leybold names DRYVAC with RUVAC WH/WSU and SCREWLINE and points out that carbon-containing by-products condense easily. For low-pressure carburising (LPC) Pfeiffer Vacuum names 1 to 10⁻² hPa at 900–1,050 °C for controlled carbon diffusion. Busch lists carburising with COBRA and PANDA/PUMA, Edwards carburising with EXS, both without further description.
What happens in vacuum hardening?
According to Leybold, the batch is heated and rapidly quenched; DRYVAC and SOGEVAC are named. For hardening Pfeiffer Vacuum names about 10⁻³ hPa at 800–1,000 °C and a clean atmosphere at high temperature. Busch names case hardening as an example of the low-oxygen furnace atmosphere.
Why does the workpiece not oxidise in the vacuum furnace?
Because there is hardly any oxygen in the furnace: the vacuum removes the air before the heating starts. Leybold describes the air-free furnace atmosphere that prevents oxidation, Edwards the oxygen-free environment; for tempering Pfeiffer Vacuum names oxide-free, reproducible heating, and for normalising less oxidation and uniform heat.
What temperatures does a vacuum furnace reach?
For the hot zone, Busch names usually 1,200 °C, and above 2,000 °C for special processes. Pfeiffer Vacuum names 150–650 °C for tempering, 800–1,000 °C for hardening, 900–1,050 °C for low-pressure carburising and 600–1,300 °C for vacuum heat treatment, for example in brazing, sintering or crystal growing.
What if by-products from the furnace put a load on the vacuum pump?
In vacuum carburising, Leybold points out that carbon-containing by-products condense easily, and names DRYVAC with RUVAC WH/WSU as well as SCREWLINE for this; in nitriding, Leybold expects a high gas load around the clock and names SOGEVAC and DRYVAC. A separator or filter upstream of the pump retains dust and condensate.
A single pump or a central vacuum system?
A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.
Does Ehrler & Beck also supply spare parts and service?
Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
