High Performance Contact Shock Freezers I – 50°C For the preparation of blood plasma storage at a core temperature of -30°C or deeper Freezing capacity: 12 plasma bags at 500 ml (450 ml content) 8 plasma bags at 1000 ml (850 ml content) Freezing time: 30 – 60 minutes, depending on load & ambient temperature Freezing time to core temperature of -30°C of 12 plasma bags at 500 ml (450 ml content) ~ 40 minutes 8 plasma bags at 1000 ml (850 ml content) ~ 55 minutes Meets the requirements for free-standing installation in Clean rooms of GMP Class A / ISO 5 ( ISO EN 14644 – 1 ) Horizontal contact shock freezing technology for:

• Blood plasma
• Pharmaceutical preparations
• Biological preparations

Advantages of the horizontal contact shock freezing technology

• Fast freezing to core temperature of – 30°C
• Automated and transparent freezing process inclusive documentation
• Simple & intuitive operation
• Evenly shaped bags for
• Optimum utilization of storage capacity
• Improved readability of labels and barcodes
• Improved further mechanical processing in automated systems
• Shock freezing of several successive batches without intermediate defrosting
• State-of-the-art compressor technology with optimized cooling system
• Air-cooled condenser
• Ergonomic design
• Quick and easy loading / removal of preparations
• Separate freezing of the fixed cover plate ( upper freezing plate ) and the electrically adjustable

working surface ( lower freezing plate )

• The preset operating temperature of -50°C minimizes the risk of bag rupturing
• Horizontal contact shock freezer for fast and even freezing times at core temperature
• Automatic process of the freezing process
• Low cost of ownership through the „Stand-By“-Modus

Supply inclusive: Temperature recorder ( Screenrecorder ) 4 – Channel Over multi-channel process und program controller with brilliant 5“-color display with 27 colors With the temperature recorder function, the temperatures

• f the upper cover plate and the lower work plate can be

recorded, as well as reference measurements for the freezing process over the dummy connection. Channel 1: Temperature „upper cover plate“ Channel 2: Temperature „lower work plate“ Channel 3: Temperature „Dummy bag“ Channel 4: „Reserve“ Dummy bag connection With the dummy connection, reference measurements at core temperature – accompanying to the freezing procedure – can be recorded. DMN Module – with B & B converter Optional Accessories: Dummy bags Reference measurements or validation processes can be done with the dummy bags during the freezing process. Either with internal measurements ( 1 x Sensor / PT100 4-adrig, Class B ), or with external measurements. Sensor for dummy bag
