HOF FTU Pharma: Freeze-Thaw Units for The Pharmaceutical Industry and Biotechnology
Adjustable freezing speed and full control over the freezing process are among the top specifi cations for freezing systems from HOF. The total fi ll quantity is frozen evenly and independent of the bag size. Each product bag has the same freezing conditions and, at the end, the same shape. This allows bar codes to be machine-read on the fl at surface, for example of a plasma bag. Reliable temperature and time documentation is a matter of course.
Reliable process control is indispensable when freezing and thawing pharmaceutical and biotechnological products. The same applies to the adjustable freezing and thawing speed. Here, with the individual Freeze Thaw Units (FTUs), HOF meets all the requirements of professional users from the industry. The FTUs are each developed and manufactured according to customer-specifi c requirements. Products that have to be fed into bag systems can be transported into the plant either manually or by means of a semi-automatic loading aid developed by HOF.
Two types are offered in order to respond fl exibly to on-site installation possibilities. The compact design accommodates all process-relevant and electrotechnical components inside the device.
On the other hand, there is the possibility of split-construction to lower the sound pressure level directly on the device. Here, the refrigeration components outside the unit are mounted on a separate machine frame.
Product tempering takes place within the FTU via a plate system. The control panels are designed to freeze the entire load evenly and regardless of bag size.
For temperature control, silicone oil is cooled with a separate cooling system or heated with the built-in electric heater. The integrated refrigeration system’s design is specified according to customer requirements. Optionally, a R452A type hydrofluorocarbon compressor system, a natural refrigerant compressor system (ethane/propene), or a liquid nitrogen system are available.
