Thermo Scientific Revco™ REB3004V/REB404V/REB1204V Blood Bank Refrigerator

Overview

The Thermo Scientific Revco™ Blood Bank Refrigerator is a purpose-engineered, microprocessor-controlled storage system designed exclusively for the safe, compliant, and thermally stable preservation of whole blood, red blood cells, platelets (when stored at permitted ambient conditions), and other temperature-sensitive blood components. Operating within a tightly regulated 1–8 °C range—factory preset at 4 °C—the unit employs a positive-pressure forced-air circulation architecture to maintain uniform internal temperature distribution across all storage zones, even during frequent door access. Its core thermal management system integrates an industrial-grade hermetic compressor, high-efficiency R134a refrigerant, and CFC-free polyurethane insulation (≥100 mm thickness) to minimize energy consumption while resisting ambient temperature fluctuations. The cabinet’s structural integrity derives from cold-rolled steel construction with scratch-resistant painted finish, adjustable leveling feet, and dual-pane glass doors with anti-condensation seals—ensuring both operational robustness and ease of cleaning in clinical and transfusion laboratory environments.

Key Features

• Positive-pressure laminar airflow system ensures rapid temperature recovery (<6 minutes to return to setpoint after 30-second door opening) and eliminates cold spots across the entire 326 L interior volume.
• Microprocessor-based digital controller with large backlit LED display (0.1 °C resolution), icon-driven interface, and visual status indicators: steady green = normal operation; top segment flashing = high-temperature alarm; bottom segment flashing = low-temperature alarm.
• Intelligent adaptive defrost logic using dedicated evaporator probe—eliminates fixed-timer defrost cycles, reduces frost accumulation, and preserves coil efficiency without manual intervention.
• Comprehensive alarm suite with audible/visual alerts for temperature deviation (HI: >+5.5 °C; LO: <+1.5 °C), power failure, door ajar, and sensor fault—configurable via key-switch lockout (ON/OFF/ALARM ON modes).
• Industrial 1/4 HP sealed compressor with automatic condensate evaporation system and maintenance-free operation over extended duty cycles.
• Six full-extension stainless steel drawers with smooth-glide rails; interior lighting activated by door switch or independent toggle (except undercounter models); optional 7-day chart recorder included (standalone unit for undercounter variants).

Sample Compatibility & Compliance

The Revco™ Blood Bank Refrigerator meets stringent regulatory requirements for blood product storage under AABB Standard 5.12 (Blood Banking), ANRC Accreditation Criteria, and U.S. FDA 21 CFR Part 606 (Current Good Manufacturing Practice for Blood and Blood Components). Its validated thermal performance supports storage of FDA-labeled red blood cell concentrates, leukoreduced units, and cryoprecipitate (when held at controlled 1–6 °C per CLSI GP44-A6). The unit is certified to UL 61010-1, CAN/CSA C22.2 No. 61010-1, and EN 61010-1 for electrical safety, and CE-marked for EMC and Low Voltage Directive compliance. Optional firmware upgrades enable 21 CFR Part 11–compliant electronic records—including user authentication, audit trail logging, and electronic signature capability—facilitating GLP/GMP-aligned quality systems in hospital blood banks and central transfusion services.

Software & Data Management

While the base controller operates as a standalone embedded system, the Revco™ platform supports integration with Thermo Fisher’s optional Revco Connect™ software suite for remote monitoring, trend analysis, and regulatory reporting. This cloud-enabled application provides real-time temperature visualization, configurable alert thresholds, automated PDF report generation (including min/max/average values per drawer), and exportable CSV data logs traceable to NIST-traceable reference standards. All recorded events—including alarm triggers, setpoint changes, and door openings—are time-stamped with ISO 8601 formatting and protected by role-based access control. For facilities requiring full 21 CFR Part 11 compliance, the system supports digital signature workflows, electronic record retention policies (configurable up to 36 months), and immutable audit trails with tamper-evident hashing.

Applications

This refrigerator serves as a primary storage solution in hospital blood banks, regional transfusion centers, blood collection facilities, and clinical research laboratories engaged in hematological studies. It is routinely deployed for: long-term holding of ABO/Rh-typed whole blood units prior to component separation; post-processing storage of packed red blood cells (RBCs) and washed RBCs; temporary staging of platelet concentrates during transport preparation (within approved ambient windows); and archival storage of reference blood panels used in serology and compatibility testing. Its space-saving footprint (74.3 × 61 cm external width) and undercounter configuration options (REB1204V) make it suitable for modular lab layouts where floor space optimization is critical without compromising thermal stability or accessibility.

FAQ

What temperature uniformity can be expected across the chamber?
Temperature variation remains ≤±0.5 °C throughout the entire usable volume under steady-state conditions, verified per ASTM F2656-22 Annex A1 thermal mapping protocol.
Is remote monitoring supported out of the box?
Standard hardware includes dry-contact alarm outputs and RS-485 Modbus RTU interface; Ethernet/Wi-Fi connectivity requires optional Revco Connect™ gateway module.
Can the unit be validated for IQ/OQ/PQ protocols?
Yes—Thermo Fisher provides comprehensive validation documentation packages, including prequalified test scripts, DQ templates, and factory-installed calibrated NIST-traceable sensors for formal qualification.
What is the warranty coverage and service support structure?
Standard coverage includes 2-year parts-and-labor warranty; extended service plans (up to 5 years) include priority response, preventive maintenance visits, and calibration certification.
Are custom voltage configurations available?
Units are configured for 230 V / 50 Hz (EU standard) at time of manufacture; 115 V / 60 Hz versions (UL/CSA listed) and three-phase variants are available upon request with lead-time adjustment.
