From design to validation

Designing, producing and installing High Purity Systems is specialist work. Smink Group has been active in this area for 30 years and delivers high-quality products, in both prefabricated form and assembled on site. We have a fully equipped workshop and a cleanroom. All our employees are professionally qualified and have the diplomas and certificates required for their work. They are experts in their disciplines and know your industry.

In-house workshop for prefabricated assemblies

Fast, flexible and above all efficient prefabrication is key to minimising the installation time on site. We build prefab piping systems, skid-mounted equipment and modules to a just-in-time schedule in our in-house workshop. Anything is possible, ranging from welding work to complete projects, including a Factory Acceptance Test (FAT). Our workshop is extremely well-equipped and even includes a pickling and passivation section and an ultrasonic bath. Products can be electro polished (EP) to a surface roughness (RA) of just 0.4 micron. We also design and produce a wide range of skids for WFI, HPW, PW and CIP/SIP systems in our workshop.

Validation programme

Each process is associated with a suitable validation programme. This ensures that the equipment we supply is completely safe, clean and operational. Various techniques are used for this.


Our 500 square metre cleanroom is available for orders placed by customers active in the semiconductor, solar, LED and photovoltaic (PVD) sectors. Our cleanroom is ISO 6 classified, but we make products here under ISO 7 conditions. The purity of the systems can be measured in terms of total organic carbon (TOC) and the number of particles present. In our ISO 6 cleanroom, we can supply products up to GRADE 2 Cleanliness. All products are subjected to a helium leak test or a nitrogen pressure drop test (stretch test).

On-site assembly

We are also extremely experienced in working on site. For example, we skilfully install pipework, and handle project and construction management. Our specialised people ensure that the complete system (including pumps, shut-off valves, control valves and other fittings and components) is correctly mounted and installed.

Custom-made products

We can supply custom-made frames and sheet metalwork for any product across a broad spectrum of industries. We ensure seamless integration with existing systems. We carry out checks, tests and perform trial runs prior to connection in the production zones. Installation Qualification (IQ) and Operational Qualification (OQ) take place under optimal conditions up to the Factory Acceptance Test (FAT). The result for the customer is a proven and documented operational system.


Smink Group is certified in accordance with the ISO 9001 quality standard and the SCC** safety standard. All technical employees have an SCC diploma and the appropriate welding certificates.
