Precision work for specials Of the 36.000 products
Teesing supplies, most come from regular suppliers. But already since our inception we produce specials when the market can’t deliver what our customer needs. To keep price, delivery time and quality under control Teesing critically assesses its partners. Yet we enter into long-term relationships with our suppliers. A good example is the machining company Centri, with…
All about fluoropolymers
When the highest level of chemical resistance is required in gas and liquid systems, plastics immediately come to mind. Teesing sells many types of plastic system components, but this article is specifically about fluoropolymers. The different types sometimes have similar resistance properties, but are still not suitable for every application. The purpose of this article…
High purity filtering in ALD and CVD processes
As the semiconductor industry moves to the sub-10 nm line nodes (such as 7nm, 5nm and smaller), nano-sized particles, once considered nuisance particles will be classified as killer defect particles. Particularly in ALD and CVD processes, the need to drive for new ultra-high purity gas filtration technology has become critical. On this scale filtration capabilities should be verified. We would like to share…
PVDF and stainless steel couplings compared
Stainless steel is often the automatic choice in industries where chemical resistance and reliability are critical. But for a large number of stainless steel applications, PVDF is also an option worth considering. For example, in the food industry, chemical industry, semiconductor industry and medical industry. PVDF often offers the same or better performance – at lower…
Influence of flow controllers on ultrasonic flowmetersInfluence of flow controllers on ultrasonic flowmeters
The operating principle of an ultrasonic flowmeter is based on the use of sound waves. This means that this type of flow meter is sensitive to sonic disturbances. In any measurement environment there will always be some form of sonic noise. Up to a certain point this is not a problem. When does it become…
Tailor-made distribution block for clean room application
VDL Klima and Teesing have worked together for many years, including on components for liquid based temperature controlling systems. This involved design, assembly and delivery. This story is about how in that collaboration you sometimes take a trip: the starting point is the first idea and together you eventually arrive at a modified design.
Gasunie is responsible for the natural gas distribution network in the Netherlands. The main transport pipeline, which runs roughly around the IJsselmeer, is 1.06 m in diameter (42″) and has a nominal pressure of 67 bar. Gasunie uses ultrasonic flow meters for flow measurement. What are the considerations for choosing an ultrasonic flow meter in…Measuring natural gas at 67 bar and with 1m diameter
A nice example of co-engineering and cleanroom assembly
Testing electronics under cleanroom conditions and in a vacuum is a challenge. Especially when it concerns high voltage electronics. In this case the customer needs a vacuum chamber that is able to test electronics under high vacuum (10-7 mbar). It is an ultra high purity application with a cleanliness of Grade 2 on the inside and Grade…

A MAGMETER WITH 30% ERROR?
Inventing and making specialty firefighting vehicles is what Innovative Fire Fighting Solutions (IFFS) is strong in. They focus mainly on systems for extinguishing water and hose systems. Fire trucks all have their own requirements regarding the amount of water on board, the flow and the distance over which water must be transported. For measuring the…
