4 Things to Look for in Manufacturing a Large Vacuum Chamber

Posted on: December 30, 2021
Anderson Dahlen’s Vacuum business segment is a leading producer of custom-made vacuum chambers. Since 1989, our team has provided unique vacuum design and build research projects to top National Labs and Universities, as well as repeat manufacturing of chambers for world-class equipment manufacturers. When working with large vacuum chambers, knowing some critical factors for success is essential. Here are Anderson Dahlen’s top four requirements to produce a high-quality, custom vacuum chamber:

1 – Quality Engineering and Design

It’s essential to have engineering and production resources to assist clients in taking their initial concepts to fully engineered designs and then to finished, tested, and ready-to-use products. For example, at Anderson Dahlen, our custom chambers can include components like domed lids, hinged doors, baseplates, frames, and hardware or flanges – depending on what the client needs. Giving clients the ability to create a custom vacuum chamber developed by professional engineers and designers allows us to meet their every need.

2 – Integrated Cooling Options

Vacuum systems sometimes include processes that generate a lot of thermal output. High thermal output vacuums require chambers with integrated cooling options like double-wall chambers, hydro-formed channels, and welded “C” channels:
  • Double Wall Chambers are used for applications that have very high heat loads. The separating chamber walls with baffles promote circulation, which provides the best method of removing heat from a system.
  • Hydro-Formed Channels provide almost double the surface area of conventional C channels. The radius bends instead of the corners, improving flow and eliminating stagnant regions. Cooling channels are produced by welding a trace to a chamber and then using water pressure to form open flow paths. Full penetration welds at channel edges reduce the risk of cracks or corrosion, extending the working life of the chamber.
  • Welded “C” Channels are best used for lower heat load systems. “C” channels are welded to a surface to provide cooling paths. Channels that are milled into the wall thickness improve thermal transfer.

3 – Meets Safety Standards

An essential component of building a vacuum chamber is to ensure it’s safe and up to the Pressure Equipment Directive (PED) and the American Society of Mechanical Engineering (ASME) ‘s standards for pressure and cryogenic requirements. By following the PED and ASME standards, engineers can ensure their work is sustainable, efficient, and safe for both clients and the environment. At Anderson Dahlen, safety is ingrained into our culture – we want to ensure that not only are our products safe to use, but our team is safe while manufacturing them.

4 – Critically Cleaned, Tested, and Inspected

When building a custom vacuum chamber, ensuring the finished product is clean and high quality is crucial. At Anderson Dahlen, all custom-made vacuum chambers go through the following inspections and tests:
  • 100% helium leak tested
  • Critical weld joints are reviewed by Certified Welding Inspectors (CWI)
  • A final dimensional inspection that utilizes our Coordinator Measuring Machine (CMM)
Quality and safety need to be top of mind when creating any product.
