HOF. The innovative force.

HOF Innovations & Products –
Technology that creates real value in practice

Innovation at HOF is not a buzzword. It emerges where requirements are high, products are sensitive, batches are valuable and technical solutions must perform with absolute reliability.

This is where HOF’s understanding of innovative strength becomes evident: in the pursuit of the best possible technical solution for demanding customer requirements. Not technology for its own sake, but equipment, systems, and technologies that reliably deliver results in real-world applications.

To achieve this, HOF combines extensive experience in pharmaceutical and biotechnological plant engineering with a commitment to exploring new approaches whenever complex challenges demand it. The result is customer solutions precisely tailored to their specific applications—from advanced refrigeration technology and controlled freezing and thawing to robot-assisted loading and unloading systems and custom-engineered solutions.

The following examples illustrate how HOF translates this innovative strength into process equipment—practical, high-performance, and future-ready.

The HOF CryoBlizzard stands for a new form of refrigeration for freeze drying and blast freezing. Instead of using conventional refrigerants, HOF relies on ambient air - naturally available, safe to use and not affected by F-Gas regulations.

Key features of the solution:

• Air as a natural refrigerant
• Low temperatures down to approx. -110 °C
• Completely exempt from F-Gas regulations
• Modularly scalable
• Efficient, low-maintenance and future-ready

The HOF Freeze-Thaw Unit Pharma was developed for the controlled freezing and thawing of sensitive biopharmaceutical products. It supports applications where precise temperature control, product integrity, and reproducible processes are critical.

Key features of the solution:

• Controlled freezing and thawing
• Precise temperature control
• Suitable for sensitive biopharmaceutical products
• Flexible for a wide range of applications
• Advanced, reliable refrigeration technology

The HOF waterbath & debottling system was developed for automated, controlled thawing of frozen plasma bottles. The bottles are then safely opened, allowing the remaining ice core to be reliably removed together with the surrounding liquid.

Key features of the solution:

• Automated, controlled thawing of frozen plasma bottles
• Safe opening and emptying
• Precise robot technology
• Reproducible processes
• Compact, reliable special solution

HOF SIRIUS is a robot-assisted high-tech loading and unloading system for demanding pharmaceutical production environments. The system handles vials safely, precisely and gently – without glass-to-glass contact and with a high level of process control.

Key features of the solution:

• safe, gentle vial handling
• no glass-to-glass contact
• robot-assisted loading and unloading
• high process reliability and traceability
• scalable for different production layouts

The HOF VTS: Vial transfer system supports safe loading and unloading processes in pharmaceutical freeze drying systems. It was developed for applications in which vials must be precisely guided, transferred in a controlled manner and reliably integrated into the plant process.

Key features of the solution:

• Safe vial handling
• State-of-the-art sensor technology
• Hygienic design
• Short changeover times
• Reliable integration into loading and unloading processes

The HOF Pharma Blast Freezer is a flexible solution for the rapid, controlled freezing of bag and bottle systems. It is designed for demanding production environments where a variety of biopharmaceutical products must be processed reliably.

Key features of the solution:

• Fast, controlled freezing
• For bag and bottle systems
• Flexible from small batches to larger pack sizes
• Temperature range from +40 °C to -110 °C
• Hygienic design and easy operation
