Cleanroom semiconductor manufacturing



We, the ECOS GmbH, are a company that had its origin in the VOEST-ALPINE Group, specialized in the construction and assembly of cleanrooms. ECOS plans and produces cleanrooms for  customers in the pharmaceutical industry, laboratories, pharmacies, microelectronics, the automotive industry, etc.
Our headquarter is located at Kirchberg am Wagram, Lower Austria, near the S5, Vienna - Krems.

Cleanroom construction Vienna - In General

We offer the planning and assembly of a cleanroom from a single source. Cleanroom planning and production is done at our company location and construction is done by our experienced  assembly operators.
Cleanroom surfaces can be done in stainless steel V2A or with a powder coating in various RAL colours.

Partners / Subcontractors / Suppliers

We insist on the highest possible quality from our partners that deliver our automatic door drives, rapid roller doors, sliding doors with our without fire safety capabilities, lighting etc.
We exclusively work with partners that we have worked with for years and with whom we had superb experiences.
Auxiliary cleanroom components like filtration technology, cleanroom furniture, cleanroom flooring (raised floor systems) or cleanroom clothing are not part of our product range but can be  supplied and delivered. We also introduce contact to on of our excellent suppliers if necessary.

Cleanroom classifications

Our cleanrooms / cleanroom ceilings / cleanroom doors and cleanroom glazings are used at positive or negative air pressure in different cleanroom classifications according to ISO 14644-1 (ISO 5 to ISO 9) or GMP Annex 1 (cleanroom class A to cleanroom class D) respectively.

Cleanroom filtration Systems / Air Filtration Boxes / Cleanroom Lighting /Cleanroom Equipment

All cleanroom components like cleanroom filtration systems, air filtration boxes or cleanroom lighting can easily be flush-mounted onto our cleanroom wall and cleanroom ceiling systems, all in the collaboration with the planners.
All cleanroom equipment and process plants are taken into account at the planning stage.
Components that are used with our cleanroom door system are connected to monitoring equipment.

Leckage test / Blower Door Test

At our company location near Vienna we built a model room which we use to test different types of cleanroom doors at various differences in pressure (10 - 100 Pascal) for tightness. We are happy to offer those results to support your efforts to design the ventilation system in the planning stage.

Resistance to disinfectants

All edges are powder-coated after stamping the components to prevent bare or blank spots.Therefore our system is resistant to all cleaning agents and disinfectants that are regularly used in cleaning and disinfecting cleanrooms.
If your company plans to use certain types of cleaning agents or disinfectants we are happy to perform resistance tests on our powder-coating. The technical university of Graz already conducted resistance tests of our cleanroom wall and cleanroom ceiling systems, as well as the cleanroom silicone used in those components, concerning hydrogen peroxide (H2O2).
A list of commercial cleaning agents and disinfectants that are useable in our cleanroom systems is readily available.

Cleanroom silicone

To produce airtight seals at the seams we exclusively use cleanroom silicone. These cleanroom silicons are certified by the hygiene institute.

Qualification and Validation

We will deliver all necessary documentation in advance as necessary.

Our Product Portfolio for Cleanroom Construction for Semiconductor Construction:


Planned to customer specifications (cleanroom class A); available with or without fire safety capabilities (E100/E190).


Highly flexible partition walls; with or without installation duct system.

Cleanroom Ceilings

In different grid dimensions available and either walkable/non-walkable.

Available in different models. Nearly no restrictions regarding locking systems or automatization; with or without fire protection capabilities according to standards E100 or E130.

Our Other Cleanroom Planning Services

Planning / Engineering / Project Management

Support of customers and their architects and technical planners at the planning stage.


Consulting concerning cleanroom planning and assembly or for special solutions and implementation details.

CAD-Drawing (2D and 3D)

Modeling and shpaing is done using 3d models, which can be exchanged in all formats for collision testing.


We use the most advanced laser-, and die-cutting systems. This cleanroom construction and assembly times short.
