HOF – the specialist

Welcome to HOF

HOF Sonderanlagenbau GmbH is the leading specialist for manufacturing high-quality, future-proof freeze drying systems, loading and unloading systems and freezing and thawing equipment. Customers come primarily from the pharmaceutical and biotechnology industries. Since its foundation in 1988, the company has consistently expanded its market share. Today, HOF has over 270 employees who provide reliable and flexible services to the national and international customers of HOF.

These services are based on 24-hour availability and an excellent team which has access the company’s own large spare parts stock with over 60,000 articles. This effectively minimises downtimes at customer sites.

Consulting

A team of experienced employees provides individual advice from the outset and accompanies all processes until the system is successfully in use. You can rely on employees who are continuously and specially trained by HOF for this task. They all have well-founded training as engineers, scientists, technicians, service engineers or skilled workers.

Innovation

Future-proof, strong and practical – these are the crucial parameters for HOF systems. HOF is known for creative products which are developed precisely to the customers’ requirements using the latest technologies. With our individual solutions and pioneering design, we successfully support our customers in reaching their objectives.

Technology

At HOF, the product is not determined by the technology, but it is rather the product properties that determine the technology. We rely on state-of-the-art technologies in our systems to achieve the best results for our customers as reliably and effectively as possible. You can rely on that!

Manufacturing

Our leading position is a constant commitment to excellent performance, continuously high quality and foresight for the development of pioneering technologies. All HOF systems are fully manufactured and tested by our employees at our production site. This allows us to ensure maximum quality.

Quality

For all HOF systems, the target is only achieved when the result fully meets your requirements – not to 99 per cent, but to 100 per cent. Following the company philosophy “quality for demanding customers on schedule”, quality is the highest standard for HOF. This applies to all areas, from concept design to customer service – you can rely on us.

Competence

The knowledge, skills and experience of our employees are the foundation for our work. Thorough, comprehensive training and constant transfer of knowledge are an important investment in the future. This contributes to safeguarding our extensive know-how and identifying with our own products while also providing you with the knowledge of making the right choice for your production.

24-hour service – 7 days a week

Comprehensive service is very important to us. That is why we do not let anyone else work on our products: We transport, install and commission your system and we qualify it. This minimises interfaces and excludes problems. HOF systems are an important component in the pharmaceutical production process. Our employees are available 24 hours a day and immediately ready to go in emergencies. Your HOF team from service and production knows every detail of your system and can help without delay.

And spare parts? No problem!

Our own warehouse with over 60,000 items ensures that the essential spare parts for all systems are always available, keeping downtimes as short as possible.

Contact our emergency service at +49 6462 9169-0 for immediate support.

HOF group of companies – specialists in demand as industry partners

The HOF group of companies has been owned by the German entrepreneur Hans-Georg Hof for decades. The company was founded by Hans-Georg Hof and Herrmann Schäfer in 1988 under the name “Schäfer & Hof Vakuum- und Kältetechnik Sonderanlagenbau GmbH”. Both already were proven specialists in their field at the time and had the required know-how and many innovative ideas. This provided the cornerstone for the high technological competence of the group of companies. The ownership situation changed in 1993 and the company was then successfully managed by Hans-Georg Hof alone under the name “HOF Vakuum- und Kältetechnik Sonderanlagenbau GmbH”.

Technological know-how as the key to success

In the following years, the company developed into the technical market leader of freeze drying systems that it is today. The continuous growth is also reflected in the high number of employees: HOF has around 270 employees today. The production area was expanded to a size of around 13,500 m² through additions and purchases.

The HOF group includes the companies HOF Sonderanlagenbau GmbH for freeze drying systems in the pharmaceutical and biotechnology industries as well as HOF Prüfsysteme GmbH – founded in 2004 – for leak testing systems in the automotive, refrigeration, electronics and space industries. The combination of comprehensive technical knowledge and high technological competence characterises the entire group of companies, turning it into a technical market leader in its field.

Relying on knowledge and experience

With almost 30 years of experience, HOF Sonderanlagenbau GmbH has been the leading specialist for manufacturing individual freeze drying systems, loading and unloading systems, and freezing and thawing equipment for the pharmaceutical and biotechnology industries.

At the company headquarters in Lohra near Marburg in Germany, highly motivated and qualified employees work in our own production facility with around 13,500 m² of floor space. Our flexible service team looks after the HOF systems and their users, maintaining close contact with customers in Germany and abroad.

Ensuring future success

Quality and reliability are the crucial parameters for the success of a product in the field of pharmaceuticals and biotechnology. This is guaranteed by the use of special-purpose systems from HOF – not in the least because the system technology of the company is developed to meet future requirements.

Power of innovation at the core of the company

HOF knows only one answer to the ever changing new requirements from customers: innovations! The company is characterised by its striving for new, better solutions, always from the customers’ perspective. The power of innovation at HOF is crucial to the success of its customers.

In 2016, 2017 and 2018, HOF was awarded the TOP 100 Seal of the Most Innovative Companies in Germany.

Highest quality in all steps

... has characterised the company specialising in individual solutions since its foundation: from concept design and fully developed planning to the conscientious manufacturing of systems that are customised and reliable. HOF systems are always a very good investment in the future.

Service without limitations

We offer service that comprises transport as well as installation, commissioning, qualification and maintenance of your systems. This also includes a 24-hour emergency service. The company’s own spare parts warehouse with over 60,000 available articles keeps downtimes as short as possible.
