Valves, measurement and control systems for semiconductor production

General information

GEMÜ Group Through continuous innovative design and a focus on quality and proximity to our customers, GEMÜ is one of today's leading worldwide manufacturers of valves, measurement and control systems. We have achieved this status by investing extensively in application-focused research and development. After more than 55 years of healthy growth, Gert Müller, son of founder Fritz Müller, now directs our independent family-owned enterprise alongside his cousin Stephan Müller. Subsidiaries and long-term partners

Reorganized - for even greater proximity to our customers. With our wide product range, we offer solutions for the most varied customer groups. To operate in a way that is more customer-oriented, strategic business units have been created: Pharma, Food & Biotech The Pharma, Food & Biotech business unit is the biggest business unit oftlos GhMUGraup. With itslargc base of user knowledge and its efficient products, it is used for all the processes of the pharmaceutical, biotechnology and cosmetics industries as well as the food and beverage industries. Irrdushfy Due to the variety of...

Global manufacture We develop and manufacture virtually all products at six different locations. At sites in Germany, Switzerland, the USA, China, Brazil and France, we draw on our many years of experience in the manufacture of valves, measurement and control systems to offer you products and solutions worldwide which conform to GEMÜ standards of quality. So that we can also continue to impress you with high quality and expert advice in the future, we are continually investing in modernizing our production centres.

Cleanroom plant For critical fluid handling, there are stringent requirements for the purity and resistance of the components used. At the GEMÜ cleanroom plant in Emmen, Switzerland, our ultra pure valves, measurement and control systems and single-use products and medical products are injection-moulded, cleaned, assembled, tested and packaged under cleanroom conditions. The factory uses the very latest manufacturing technologies and achieves cleanroom quality in accordance with ISO class 8 (in operation) as well as GMP class C. This level of quality applies to the entire manufacturing...

Technical consultation and service range The correct installation and predictive maintenance of valves, measurement and control components are important prerequisites for efficient operation and optimum operating cycles for a plant. This is why we also support you in this regard and offer various additional services.

All-round service Our well-trained advisors and service engineers support designers, equipment manufacturers and operators, in addition to service providers, in planning, configuring, commissioning and maintaining pipework components. They have in-depth knowledge of the market and can find the optimum technical and cost-effective product version for the relevant application from our comprehensive range. Repair and maintenance work can be carried out at the service centres or directly on site. If you wish, our qualified fitters can also assume responsibility for component inventory, data...

Semiconductor business segment GEMÜ has excellent references for the use of valves in areas of application that have high purity requirements.

Wafer manufacture Silicon (sand, quartz), which is a typical semiconductor (conductivity lies between that of conductors and nonconductors), is generally used to manufacture wafers. First, the silicon is melted and purified several times, chemically and metallurgically. Process requirements • High resistance to abrasive and corrosive media • Long service life • Precise control of cutting and grinding slurries used Out of this purified silicon melt, a silicon cylinder (ingot) is extracted from a seed crystal. Discs (wafers) of less than 1 mm are then sawn off from this. After that, the edges...

Chemical manufacture Numerous chemicals, slurries and solvents are required for semiconductor production. The varied processes in the chemical industry have stringent requirements for the valve technology employed here. Specific valve and component solutions are therefore much in demand when dealing with critical working media, high temperatures and high pressures. Process requirements • High purity materials and uncompromising resistance • Long service life • Low-impact media handling at high Kv val
