Biobase BBR-4V136 Blood Bank Refrigerator
The BBR-4V136 is a state-of-the-art, single-door vertical blood bank refrigerator optimized for secure, low-volume storage of whole blood, plasma, and erythrocytes in demanding clinical environments. Constructed with a powder-coated galvanized steel exterior and high-impact ABS interior, it features a robust insulation layer of 70 mm thick CFC-free polyurethane foam to minimize thermal bridging and maintain ultra-stable conditions. Advanced safety protocols include a triple-pane vacuum-insulated glass door with magnetic seals to prevent frost buildup, an auto-defrost cycle with adaptive humidity control, and a fail-safe backup battery for alarms during power events, ensuring uninterrupted protection for up to 72 hours of shelf life extension per AABB standards in blood banks, transfusion centers, and small hospital labs.
Description
Performance and Temperature Control: Maintains a precise operating range of 2–6°C with 0.1°C display accuracy and ≤1.5°C uniformity across the chamber, powered by a high-efficiency forced-air circulation system using an eco-friendly R134a refrigerant. The microprocessor controller achieves ≤2°C stability even under frequent door openings, with real-time compensation for ambient fluctuations up to 32°C. Digital PID algorithms optimize compressor cycling for energy efficiency, reducing power draw by 25% compared to legacy models, while the evaporator’s anti-frost coating ensures consistent cooling without ice accumulation, supporting reliable preservation of temperature-sensitive biologics like cryoprecipitate or factor concentrates.
Storage Capacity and Configuration: Offers 136 L of net storage volume, accommodating up to 120 standard 450 mL blood bags arranged on five adjustable stainless-steel shelves (each 25 kg load capacity) for optimal FIFO inventory management. The interior height of 580 mm and width of 475 mm allow flexible shelving adjustments in 50 mm increments, with optional wire baskets or blood bag carriers for customized organization. LED illumination (10W, ≥300 lux) activates automatically upon door opening, providing clear visibility without heat generation, while the 1.2 m² door gasket ensures airtight closure to safeguard against contamination.
User Interface and Operational Features: Equipped with a user-friendly 4.3-inch color LCD touchscreen displaying temperature trends, high/low setpoints, and door-open duration, with multilingual support (English, Spanish, Chinese) and password-protected admin modes for GLP compliance. Programmable alarms include audible/visual notifications for deviations >±2°C, power failure, or sensor faults, integrated with optional remote monitoring via RS485/USB ports. The soft-touch controls allow one-button defrost initiation and data logging at 1-minute intervals, streamlining daily audits in busy transfusion workflows.
Sterilization and Maintenance: The seamless ABS plastic interior with coved corners facilitates wipe-down with 70% isopropyl alcohol or quaternary disinfectants, while the evaporator drip pan auto-evaporates condensate to prevent bacterial growth. Self-diagnostic routines run at startup, flagging issues like compressor overload or probe drift, with a maintenance interval indicator for annual filter checks. The hermetically sealed compressor requires no lubrication, and the unit’s modular design enables tool-free shelf removal for deep cleaning, backed by a 3-year warranty on core components for long-term dependability.
Electrical and Environmental Specifications: Operates on a standard AC 220V/50Hz (110V/60Hz optional) supply at 150W, featuring a low-voltage start-up (180V tolerance) and surge suppression for reliable performance in variable grid conditions. Designed for ambient environments of 10–32°C and ≤70% RH, it includes a heated door frame to eliminate external condensation and a noise level <45 dB for quiet lab integration. Energy consumption averages 1.2 kWh/24h, qualifying for green lab certifications.
Dimensions and Installation Flexibility: Compact external footprint of 525 × 490 × 1440 mm (W × D × H) weighs 65 kg, with adjustable leveling feet for uneven floors and optional casters for mobility in compact blood stations. The reversible door swing (left/right) and slim 50 mm profile enable side-by-side installation, while the top-mounted ventilation grille requires only 10 cm rear clearance. Pre-wired with a 2 m cord and NEMA 5-15 plug, it installs in under 15 minutes without specialized tools.
- Throughput and Workflow: Supports storage for 80–120 donor units with rapid 30-second door recovery time, enabling efficient 24/7 access in small-scale blood processing for up to 200 daily transactions.
- Detection and Monitoring: Triple-redundant PT1000 sensors (cabinet air, evaporator, door) with 0.01°C resolution; logs 10,000+ events including excursions and recoveries for regulatory traceability.
- Detection Principle: Forced convection cooling with variable-speed fans for uniform stratification, combined with adaptive defrost to sustain microclimate stability.
- Additional Features: Built-in thermal printer for daily temperature charts; SNMP-compatible Ethernet for cloud alerts; supports barcode label holders on shelves. Multi-alarm relay outputs for integration with facility BMS.
- Data Storage: 5-year internal memory for historical graphs and audit trails, exportable in CSV/PDF via USB; tamper-evident event logging.
- Sample Handling Modes: Optimized for whole blood bags, plasma packs, and reagents; compatible with inventory management racks for automated stock rotation and expiration tracking.
