AUCMA YC-180 Pharmaceutical Refrigerator (2–8°C)

Overview

The AUCMA YC-180 Pharmaceutical Refrigerator is an ISO-compliant, microprocessor-controlled cold storage unit engineered for precise, stable, and traceable temperature maintenance between 2°C and 8°C. Designed in accordance with WHO Technical Report Series No. 961 (2011) and aligned with ICH Guidelines Q5C and Q7 for biopharmaceutical storage, this refrigerator serves as a primary storage solution for temperature-sensitive pharmaceuticals—including vaccines, monoclonal antibodies, diagnostic reagents, clinical trial materials, and GMP-grade reference standards. Its forced-air convection architecture ensures uniform thermal distribution across the entire 180 L working volume, minimizing spatial temperature gradients (< ±0.8°C at steady state per ASTM F2657-22 test protocol). The unit meets Class II performance criteria under EN 61000-6-3 (EMC) and EN 60335-2-24 (safety), and its control system supports audit-ready operation in regulated environments requiring GLP, GDP, or FDA 21 CFR Part 11 compliance when integrated with validated data logging software.

Key Features

• Microprocessor-based digital temperature controller with 0.1°C resolution and real-time display—calibration traceable to NIST-traceable references.
• Forced-air cooling system utilizing an imported high-efficiency rotary compressor and brushless EBM EC fan motor, enabling rapid pull-down (≤3.5 h from 25°C ambient to 5°C setpoint) and recovery (<15 min after 60-sec door opening).
• Multi-layer alarm architecture: audible (85 dB) and visual (LED flash) alerts for high/low temperature deviation (>±2°C), door ajar (>30 sec), power interruption, sensor failure, and internal backup battery voltage drop.
• Remote alarm interface via dry-contact relay output compatible with BMS, SCADA, or centralized laboratory monitoring platforms (e.g., DeltaV, Siemens Desigo, or custom SNMP-enabled systems).
• Double-glazed, low-emissivity coated glass door with anti-fog heating element—reducing condensation without compromising insulation integrity (U-value ≤ 0.8 W/m²·K).
• Three independently adjustable stainless-steel wire shelves plus one removable wire basket; all load-rated to 15 kg per shelf with non-slip coating.
• Wide-input voltage design (187–242 V AC) with built-in surge suppression and automatic restart delay (≥3 min) to protect compressor during grid fluctuations.

Sample Compatibility & Compliance

The YC-180 accommodates standard ISO 554 (1976) conditioned ambient loads up to 180 L total volume, supporting common secondary packaging formats including vial racks (2R–50R), PCR tube boxes, cryoboxes (up to 10×10 configuration), and multi-compartment specimen trays. Internal airflow mapping confirms ≥0.2 m/s velocity at all shelf levels, ensuring adequate convective heat exchange for heterogeneous sample loads. The unit complies with EU GDP Annex 9 requirements for medicinal product storage and satisfies USP standards for environmental monitoring of refrigerated storage areas. Optional factory-installed temperature mapping validation kits (per ISO 14644-3) and IQ/OQ documentation packages are available for GxP-regulated installations.

Software & Data Management

While the YC-180 operates as a standalone device, its analog/digital alarm outputs and RS485 Modbus RTU port enable seamless integration with third-party data acquisition systems. When paired with compliant continuous monitoring solutions (e.g., DicksonOne, Sensitech TempTale®, or ELPRO Libero®), the unit supports full electronic record retention, user-access controls, event-driven notifications (SMS/email), and 21 CFR Part 11–compliant audit trails—including operator ID, timestamped parameter changes, alarm acknowledgments, and calibration history. Local data logging via optional USB datalogger (sold separately) captures 30-day temperature history at 10-minute intervals with CSV export capability.

Applications

• Hospital pharmacy cold chain management for vaccine inventory (e.g., mRNA, viral vector, and adjuvanted formulations).
• QC/QA laboratories storing reference standards, calibration materials, and stability study samples per ICH Q1A(R2).
• Clinical research sites maintaining biospecimens (serum, plasma, CSF) prior to freezing or shipment.
• Contract development and manufacturing organizations (CDMOs) operating GDP-aligned warehouse staging zones.
• Public health laboratories conducting national immunization program logistics under WHO PQS specifications.

FAQ

Does the YC-180 meet WHO PQS requirements for vaccine storage?
Yes—the unit’s temperature uniformity, stability, and alarm response time align with WHO PQS Technical Specifications for Refrigerated Cold Boxes and Vaccine Refrigerators (2022 Edition), particularly Sections 5.2 and 5.4.
Is external temperature monitoring required for GxP use?
Per FDA Guidance for Industry: Process Validation (2011), independent continuous monitoring is mandatory for any critical storage environment; the YC-180’s relay and Modbus interfaces facilitate such integration.
Can the unit be validated for IQ/OQ/PQ protocols?
Yes—AUCMA provides factory-issued test certificates (temperature mapping reports, electrical safety, and alarm verification), and full qualification support documentation is available upon request.
What is the mean time between failures (MTBF) for the compressor system?
Based on accelerated life testing per IEC 60068-2-64, the integrated compressor-fan assembly demonstrates an MTBF > 50,000 hours under nominal 2–8°C operation.
Are spare parts and service support available internationally?
AUCMA maintains authorized service partners across APAC, EMEA, and LATAM regions; critical spares (control board, sensor assemblies, door gaskets) are stocked with ≤72-h lead time for most markets.
