Certified quality, hand-made pressurised containers

A pressurised container is a versatile, sealed container or vessel that can be used in development laboratories as well as in large production facilities. The pressure inside the container is higher than the ambient pressure, thereby making pressurised processes, such as sterilisation or transfer, safe.

Pressurised containers are a necessity for research, development and production work in diverse industries. Many processes would simply be impossible without them. If you are looking for a high-quality container, you have come to the right place at Waldner. We manufacture durable, robust and safety-tested custom-made pressurised container, which will fit seamlessly into your production processes.

You will be persuaded by the many benefits of Waldner pressurised containers. Their quality is one of their main benefits. They are manufactured from extremely stable, durable and high-quality components and produced with precision workmanship. This creates a product that will perfectly fulfil its purpose over many years to come.

Waldner also produces custom-made pressurised containers to meet exacting customer requirements. Do you need a small, simple pressurised container? Or are you looking for a large container to withstand particularly high pressure? Together with you, we will design a tailor-made pressurised container that will meet all the necessary safety standards and can be equipped with a wealth of features (e.g. including an agitator) to meet your requirements.

Conforms to AD-Regulations, DGRL and ASME

Pressurised containers are governed by strict safety regulations – and rightly so. Working with substances under pressure comes with high potential risks. Safety standards of all kinds ensure that the pressurised containers are safe to use, and that damage to property and personnel is avoided. 

Naturally, Waldner designs and manufactures its pressurised containers in compliance with all the current standards and regulations, including ATEX, DGRL, AD2000, DIN EN 13445, ASME, and TR certificates. This ensures that our products are safe to use and are ideally equipped for all markets.

Pressurised containers – from the initial concept to the finished product

As a renowned manufacturer of pressurised containers, Waldner understands that only containers tailored perfectly to the process workflows can really work effectively. That is why every Waldner pressurised container is unique. At the quotation phase, we develop a customised solution to meet your requirements and create a detailed 3D-CAD design of your pressurised container at the start of the project.

Production starts when you are satisfied with the design. Standard stainless steel materials, including 316L (1.4404/1.4435) or 304 (1.4301), are used as the basic material of the containers. Waldner also relies on coatings, such as PTFE or Halar, as well as special alloys, such as Alloy and Hastelloy. We then manufacture your product from these materials using the latest welding and grinding technology.

The ultimate engineering workmanship

Waldner engineers will support your project from the planning phase right through to factory handover. They will supervise all tests and inspections, including non-destructive material tests, surface roughness measurements or CIP cleaning certificates, and will put the containers through all the relevant functional tests.

Design and equipment – your options

The custom-manufacture of the pressurised containers is not just restricted to the material. A wealth of design and equipment characteristics can also be adapted to suit your needs:

  •  -1 to 10 bar pressure resistance
  • 1 to 15,000-litre volume
  • Free-standing, horizontal or suspended design
  • Single-walled or multi-walled construction
  • A range of closure designs
  • Pressurised containers with a lid or sealed
  • A range of measuring instruments and valves
  • Waldner docking system to connect the pressurised container to an isolator
  • Filter and upper shelves that can be lowered, raised and swivelled
