Revenue model

1. Custom freeze-drying and process equipment manufacturing: HOF manufactures individually designed and engineered-to-order freeze-drying systems, freeze-thaw units, loading/unloading systems, and related process equipment for pharmaceutical and biotechnological applications. Revenue is generated through one-time capital equipment sales with substantial custom engineering content. Each system is tailored to specific customer production requirements, requiring significant pre-sale consultation and custom engineering.
2. Professional services (qualification, commissioning, process development): Comprehensive project services covering the entire equipment lifecycle including qualification and validation documentation (IQ, OQ), process development support, on-site commissioning and SAT, design and concept studies in 2D/3D, and annual calibration. These services are bundled with equipment sales and represent a recurring service component.
3. Aftermarket services (maintenance, spare parts, training): Annual maintenance contracts, spare parts supply from in-house warehouse of over 60,000 items, remote support (TeamViewer quick support), and customized training programs. The company emphasizes that its own employees handle all service work even after equipment leaves the factory, maintaining a continuous customer relationship and recurring service revenue.

Partnerships

Two partnerships are on record, tiered core.

• SartoriuscoreStrategic or Co-development PartnerHOF and Sartorius have established a cooperation agreement in which Sartorius offers optimized Freeze-Thaw Units (FTU) for applications with Celsius FFTp bags, manufactured by HOF. This allows Sartorius to provide its customers with a fully integrated freezing and thawing solution for its single-use bag systems. HOF provides the FTU hardware and software while Sartorius incorporates it into its fluid management and frozen storage/shipping portfolio for biopharma customers.
• Mirai IntexcoreStrategic or Co-development PartnerMirai Intex (mirai-intex.com) served as the key project partner for the co-development of HOF CryoBlizzard, the innovative cold-air refrigeration technology. Mirai Intex contributed expertise in Brayton cycle air refrigeration systems, including the turbo compressor-expander technology with air bearings. The partnership has resulted in a commercially viable GWP 0 refrigeration system for pharmaceutical freeze-drying applications.
