Founded in 2001, HSR AG is a manufacturer of high vacuum pumps and components used for
a wide range of modern production processes and applications.
Initially the company developed and manufactured a new generation of cryogenic pumps.
Responding to current customer requirements, the product portfolio has been expanded to
new business segments such as diffusion and UHV-pumps as well as high-vacuum plate and
angle valves.
Thanks to its continuous development, HSR is able to supply today a complete portfolio of cryogenic and diffusion pumps as well as high vacuum valves including accessories. In addition to these components, the company offers engineering capabilities for the development and delivery of customized devices and solutions for special projects in the field of vacuum technology. In close cooperation with the customer, we give highest priority to the efficient implementation of requirements and specifications as well as the development of economic and process-optimized solutions.
Based in Balzers, Liechtenstein, HSR has expanded its existing sales structure in 2009 by establishing a subsidiary, HSR Vacuum GmbH near Frankfurt, Germany. A worldwide network of partners and representatives guarantees fast and reliable service and support on customer site.
HSR AG’s cryogenic pumps are, amongst other things, known for their impeccable performance data and reliability in use. Long operating periods between necessary maintenance breaks provide for high availability as well as seamless and cost effective operation. Apart from their use in high-vacuum and ultra high-vacuum pumps, HSR’s cryogenic pumps are particularly suited for:
• Thin-film coating machinery
• Space simulation chambers
• Sputter equipment
• Fusion test systems
• Particle accelerators
• Thermal coating systems
• Metallization equipment
HSR oil diffusion pumps can be used in many applications in the fields of vacuum and high-vacuum technology, for example in metallizing systems, metallurgical facilities, vacuum furnaces, laboratory pumping stations and many more. The proven and tested diffusion pump technology of former Balzers AG has been developed further by HSR AG since they took over this business area in 2003. In keeping with our standards, our customers can always expect the highest quality and performance from our products.
