Stainless steel pressure vessels

for the pharmaceuticals industry, biotechnology, and the food industry

Edelstahl NORD is your specialist for pressure-resistant preparation tanks and process vessels for the production, processing and storage of fluid media in the pharmaceutical industry and the food industry. Our customers also value our employees many years of experience with planning and producing fermenters and bioreactors of the highest quality.

Our design engineers develop application-specific recommended solutions for you, whether you need a single vessel, a unit including an agitator, measuring devices or a control system.

At the start of your project we ensure a hygienic design and adherence to the nationally and internationally applicable standards, e.g. GMP, FDA or the Pressure Equipment Directive.

Your decision for a pressure vessel from Edelstahl NORD is also a decision for a simple process validation inside your company, product progress and a long-term process reliability.

The offer, which is tailored to your process, is created personally by the employee who consulted with you at the start of your project.


The strength calculation of the pressure vessels is completed by our employees.


Our designers have a special appreciation for gap and dead space-free design for process containers, fermenters, and bio-reactors.


We only process stainless steel at our modern machine park. Our production area covers 5,000 m².


Approval of design and Third Party Inspection can be accomplished by Notified Body of your choice.


Upon request we complete extensive testing together with you at our premises, e.g the riboflavine test, agitator test, pressure hold test, etc.


Upon customer’s request we can organise the transport of your vessel. In order to avoid any damages during transport, our employees ensure suitable packaging for your process vessels, suitable even for sea freight.


Edelstahl NORD employees will help you with commissioning and training for your employees upon request.
