By "industrial applications" we mean a wide range of production processes that require vacuum technology. The common denominator of these applications such as steel degassing, heat treatment or vacuum drying is their use of pumps in challenging industrial type environments. They need to handle “more than just air” and must cope with this. Exactly what our industrial pumps are made for.
One of the drivers in the field of vacuum furnaces is the ever-increasing demand for high-quality metal parts from the aerospace and automotive industries. These sectors demand modern components that are capable of meeting the highest standards. These standards can usually only be achieved by heat treatment under vacuum.
Unexpected furnace downtimes cause high production costs, as the production steps are usually designed according to the just-in-time model. The various heat treatment applications present different challenges for the vacuum systems used.
Since 1850, our customers worldwide rely on our experience and expertise. Leybold offers the best vacuum technology for every heat treatment application.
Metallurgy / Steel Degassing
Secondary steelmaking involves refining of the crude steel coming from the primary metallurgy production steps. The various operations are normally carried out in ladles. In secondary metallurgy, alloying agents are added, dissolved gases in the steel are lowered, the carbon content is reduced and inclusions are removed or altered chemically to ensure that high-quality steel is produced after casting. Many process steps are performed under vacuum which is necessary to ensure highest steel quality levels.
The traditionally utilized steam-ejector vacuum systems are today more and more displaced by the clearly more energy saving and environmental friendly mechanical vacuum systems. By the development of extreme robust dry compressing screw vacuum pumps which are combined with Roots-type booster pumps, mechanical vacuum systems reached the required reliability level to enable highest steel production yields.
Lithium Ion Batteries
The move toward e-mobility requires future-proof solutions in the energy storage technology in order to meet the increasing demand for electric transportation.
The requirements and solutions regarding the service life of energy storage systems and their ranges are increasing. One of the reasons why electric cars, scooters and bicycles are becoming more and more attractive. Intensive technological research, resulting in a constant development has led to Li-ion cells being the dominant technology in e-mobility today. Global networking requires ever more flexible, faster and, above all, mobile communication.
Smartphones, laptops and other mobile devices are an integral part of everyday life in many parts of the world. Thanks to the increasingly compact, durable and efficient lithium-ion batteries, devices are getting smaller and smaller, and more affordable.
Leybold products are adapted to all relevant production steps and offer the best solution for the most diverse requirements.
New Energy Solutions and Energy Transformation
The energy transformation we strive for is a major technical challenge, but green energy generated by photovoltaic and wind power plants is not adapted to current energy needs. Surplus energy requires high-quality intermediate storage facilities in order to provide generated energy that’s in line with demand. There’s a growing demand for storage solutions such as flywheels and hydrogen cells.
Electromobility also requires efficient energy and energy storage solutions in order to increase its attractiveness through longer distances and lower production costs. For these reasons, hydrogen fuel cells are undergoing continuous development, and the fuel cell is increasingly coming into focus.
All these technologies pass through vacuum-assisted production steps which require specific vacuum solutions. Leybold products are adapted to all relevant manufacturing steps and offer the right solution for the most diverse requirements.

Vacuum supports numerous manufacturing processes where products need to be charged with gases or liquids. Examples include refrigerant circuits for air-conditioners and refrigerators, automotive brake lines, heat-pipes and gas-filled lamps.
Before the final gas or liquid can be charged, it’s important, to ensure that the volume to be filled is evacuated in order to provide a clean and dry space as well as “bubble-free” charging. Imagine moisture inside your brake line which could make your brake fluid freeze in winter or air bubbles which would make your car's brakes less efficient.
The challenges of charging applications are numerous. Surely air, but often moisture and even liquid droplets need to be pumped from the space. During the evacuation of gas bottles, the vacuum pump must also sometimes handle harsh process gases, e.g., from the semiconductor industry. Depending on the level of cleanliness required, evacuation into high-vacuum is sometimes required.
Leybold has decades of experience with all kinds of charging applications. Our products are applicable to most industries. Come see us if you need vacuum for charging.
