70 years of experience in UHP systems for gases and liquids


We are a specialist in (ultra) high purity systems for gases and liquids in the high-tech sector. We started in 1952 as a local Dutch trade company, nowadays we are an international company with a N-tier track record at leading International OEM companies in the high-tech sector . We have developed towards a system integrator for many dedicated long term customers and partners with an international supply chain.  That's why Teesing decided to enter the European market in June 2022. 

The industry in which we operate will grow significantly in the next decade. The planned semicon fabs and the ambition of the European Union to become more independent in the semicon field are typical. This type of market development isn't new. It happened before. And Teesing Systems was there. We are sure we can follow changing demands and requirements in these exiting times.


The transport and control of ultra pure gases and liquids is our core business and has been since 1952. Our installations and products are manufactured in our ISO class 4 cleanroom - leak tight and clean. Customers are OEMs and end-users active in semiconductor, optical, nuclear and pharmaceutical industries. R&D parties, universities and the high-tech industry.

Together with our customers and suppliers, we focus on achieving the highest level of quality possible. We enable our customers to control their production by being a reliable partner in the supply chain. We work efficiently, innovatively and have the highest standards for our products. By carefully selecting our suppliers, we maintain focus on quality standards and purity requirements.


A 100% focus on our customer's success is what makes an international business successful. We have gained this knowledge with the establishment of our own offices in China (2001), the USA (2004) and Taiwan (2009).
