Biobase BBR-4V296 Blood Bank Refrigerator
The BBR-4V296 is a high-capacity, single-door vertical blood bank refrigerator engineered for large-scale storage of whole blood, packed red cells, plasma, and platelets under AABB, WHO, and cGMP guidelines. Its double-walled galvanized steel shell with 80 mm CFC-free high-density polyurethane insulation creates a thermal barrier that withstands >100,000 door cycles. The heated triple-pane argon-filled glass door with anti-condensate coating and full-perimeter magnetic gasket prevents frost and air leaks, while the auto-close hinge and keyed lock with digital audit trail ensure 21 CFR Part 11-compliant security in central blood banks, regional transfusion services, and hospital blood centers.
Description
Performance and Temperature Control: Delivers +4°C ±1°C across the entire 296 L chamber with ≤1.0°C spatial uniformity and ≤0.5°C temporal stability, driven by a variable-speed EC compressor and forced-air multi-duct convection. Uses R290 hydrocarbon refrigerant (GWP <3) for 40% lower energy than R134a models. The dual evaporator system with hot-gas bypass defrost completes cycles in <8 minutes without temperature excursions >0.3°C. Real-time adaptive PID control compensates for ambient 10–35°C and door openings up to 60/hour, with <2-minute recovery to setpoint.
Storage Capacity and Configuration: Provides 296 L usable volume, holding up to 252 standard 450 mL blood bags (6 shelves × 42 bags) or 360 × 200 mL pediatric units. Six height-adjustable epoxy-coated steel shelves (500 × 450 mm, 40 kg load each) feature integrated label rails and pull-out stops. Optional stainless-steel roll-out drawers (12 × 25-bag) enable FIFO rotation and inventory scanning. Interior LED strips (≥500 lux, dimmable) and transparent inner door flaps (optional) reduce cold air loss by 70% during access.
User Interface and Operational Features: 7-inch capacitive touchscreen with glove-friendly UI displays live temperature mapping, door-open heatmap, and predictive maintenance alerts. 30 user profiles with RFID/NFC login; multilingual interface (12 languages). Programmable access schedules (e.g., night lockdown) and remote override via mobile app. USB-C and Ethernet ports support cloud syncing; SNMP/Modbus for BMS. Built-in thermal chart recorder (7-day) and backup CO2/LN2 injection port for emergency cooling.
Sterilization and Maintenance: 304 stainless-steel interior with coved corners and auto-evaporative condensate tray resists 10% bleach and quaternary disinfectants. Tool-free removable air duct for quarterly deep-clean. Self-calibrating PT1000 sensors with ±0.05°C accuracy; filter-less condenser requires no PM dust cleaning. Predictive diagnostics forecast compressor life (>50,000 hrs) and alert at 80% capacity. Modular refrigeration cassette replaces in <30 min without moving unit.
Electrical and Environmental Specifications: AC 220V/50Hz (110V/60Hz auto-switch) at 280W average, with <1.8 kWh/24h consumption. UPS-ready 48V DC input (optional) sustains alarms >96 hours. Operates in 10–35°C, ≤75% RH, with <48 dB acoustic signature. IP54-rated electronics and seismic tie-down points for high-risk zones.
Dimensions and Installation Flexibility: External: 700 × 680 × 1980 mm (W × D × H); weight 145 kg. Reversible door, pass-through capable, and under-counter height option (with pedestal). Requires 15 cm rear / 5 cm side clearance. Ships pre-charged with forklift base and ramp kit for single-person install.
- Throughput and Workflow: Stores 252 donor units with <30-sec door recovery, supporting >500 daily transactions in regional blood centers.
- Detection and Monitoring: Quad-redundant PT1000 sensors + IR door sensor; logs 1 million+ events with 1-sec resolution (temp, door, power, alarms).
- Detection Principle: Multi-duct forced convection + hot-gas defrost + variable-speed EC fan/compressor for microclimate precision.
- Additional Features: Integrated barcode scanner mount; Wi-Fi temperature beacon for bag-level tracking; CO2 backup solenoid with auto-switch.
- Data Storage:10-year onboard memory; encrypted export (CSV/PDF/XML); FHIR/HL7 interface for EHR integration.
- Sample Handling Modes: Configurable for whole blood, RBCs, FFP, cryoprecipitate, platelets (with agitation rack option); supports RFID-tagged bags and automated expiry alerts.
