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: 21 plasma bags at 500 ml (450 ml content) 14 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 21 plasma bags at 500 ml (450 ml content) ~ 40 minutes 14 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 ) and with an external Water cooling unit, the requirements for a free-standing installation in Clean rooms of GMP Class B / ISO 6 ( 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
• High-grade Stainless steel housing
• Mobility by means of heavy castors with brakes
• Compact, service- and maintenance friendly construction, easy cleaning and disinfection, as

accessible from all 4 sides

• Low surface area needed
• Delivered ready to use ( 3ph 400 V / 50 Hz, 16 A )

Arrangement possibilities 14 plasma bags at 1000 ml

Control elements Technical Data Exterior dimensions: 1600 x 1470 x 770 mm (H x Wx D) Contact plates dimensions: 970 x 620 mm (W x D) Net weight: 400 Kg Defrosting: Hot gas (manuel over „Operating mode“ switch) Defrosting time: 8 min (as preset safety factor) Material outer casing: Stainless steel (V2A – 1.4301) Compressor: Bitzer Refrigerant type: R507 Climate class: N Ambient temperature: +16°C to +32°C Relative humidity: ≤ 70% at +32°C ambient temperature Energy consumption: 6,0 kWh / freezing cycle Power: 3000 W Voltage (3ph): 3 ~ 400 V / 50Hz (16A) Safety class: I GMP Clean room classification: Class A / ISO 5 ( ISO EN 14644-1) Control & operating element: Jumo Imago 500 Temperature sensors: PT 1000, in each contact plate

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.

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 External water-cooling Air-cooled condensers and compressors as external unit In order to avoid accumulating excessive heat inside the room, we can provide you with an external installation of the cooling system. This allows that the room temperature does not rise too much and you therefore have a better Delta T between the room temperature and the operating temperature of the MBF. Barcoder reader
