Medical Refrigerator YC-520L by Jihepu

Overview

The Jihepu YC-520L Medical Refrigerator is a purpose-built, CE-compliant cold storage unit engineered for the secure, stable, and auditable refrigeration of temperature-sensitive pharmaceuticals, vaccines, blood components, diagnostic reagents, and biological specimens in clinical laboratories, pharmacies, hospital central supply departments, and GMP-compliant manufacturing environments. Operating within the strictly regulated 2–8°C range—aligned with WHO guidelines for vaccine storage and USP standards for pharmaceutical cold chain integrity—the unit employs forced-air circulation to achieve uniform temperature distribution (±0.5°C spatial uniformity across all shelf levels per ICH Q5C verification protocols). Its microprocessor-controlled PID temperature regulation system continuously monitors internal conditions via dual redundant NTC sensors, maintaining setpoint stability within ±0.3°C under dynamic load conditions (e.g., frequent door openings or ambient fluctuations between 16–32°C). The cabinet’s structural integrity and thermal performance are validated against ISO 23374:2021 (Medical refrigerators — Performance requirements and test methods), ensuring compliance with global regulatory expectations for medical-grade cold storage.

Key Features

• Forced-air cooling architecture with intelligent fan modulation ensures rapid pull-down (<3 hours from 25°C ambient to 4°C setpoint) and minimizes thermal gradients across the 520 L storage volume.
• Double-glazed, low-E tempered glass door with integrated anti-condensation heating circuit eliminates fogging during high-humidity operation while preserving visibility and energy efficiency.
• High-precision digital display with 0.1°C resolution and real-time logging capability supports GLP/GMP documentation requirements; thermal printer provides timestamped hard-copy records with embedded backup battery (72-hour runtime).
• Comprehensive alarm suite includes configurable high/low temperature thresholds, door-open duration monitoring (>30 sec), sensor failure detection, and mains power interruption alerts—each triggering both audible (85 dB) and visual indicators with event-stamped log entries.
• Robust mechanical design: 304 stainless steel interior liner resists corrosion and facilitates decontamination; 60 mm CFC-free polyurethane insulation achieves U-value ≤0.25 W/m²·K; heavy-duty castor wheels with locking brakes enable safe relocation within clinical workflows.
• Energy-efficient R134a refrigeration system paired with a high-torque, low-vibration compressor meets IEC 60335-2-24 safety standards and complies with EU Regulation (EU) No 517/2014 on fluorinated greenhouse gases.

Sample Compatibility & Compliance

The YC-520L accommodates standard clinical storage configurations—including stacked trays, cryoboxes (up to 10×10 format), vial racks, and IV bag holders—without compromising airflow or temperature homogeneity. Its interior layout supports ISO/IEC 17025-aligned validation practices: temperature mapping studies confirm ≥90% of volume maintains 2–8°C under worst-case loading (90% capacity, half-door open for 60 sec every 15 min over 24 h). Regulatory documentation includes full technical files compliant with China NMPA Medical Device Registration (Class II), ISO 13485:2016 certification for design and manufacturing controls, and conformity assessment reports aligned with MDR Annex II requirements for ancillary cold chain equipment. All materials contacting stored products meet USP extractables profile criteria.

Software & Data Management

While the YC-520L operates as a standalone, non-networked device per IEC 62304 Class A software safety classification, its embedded firmware supports 21 CFR Part 11–compatible audit trails: each temperature reading, alarm activation, and user-initiated action (e.g., setpoint change, alarm silence) is time-stamped, user-ID logged (via physical key access), and irreversibly recorded in non-volatile memory. Thermal printouts include QR-coded batch identifiers for traceability linkage to LIMS or electronic quality management systems (eQMS). Optional RS-485 Modbus RTU interface enables integration with facility-wide environmental monitoring systems (EMS) for centralized alarm aggregation and long-term trend analysis.

Applications

• Hospital pharmacy cold rooms for insulin, monoclonal antibodies, and mRNA vaccine intermediates
• Clinical trial material storage complying with ICH GCP Annex 13 temperature excursions limits
• Blood bank component refrigeration (RBCs, platelets) meeting AABB Standard 5.10.1
• QC/QA labs storing reference standards, calibration materials, and stability study samples per ICH Q1A(R2)
• Veterinary clinics and biobanks requiring ISO 20387:2018-compliant specimen preservation infrastructure

FAQ

Is the YC-520L certified for use in FDA-regulated facilities?

Yes—its ISO 13485:2016 Quality Management System certification, NMPA Medical Device Registration, and adherence to IEC 60601-1 collateral standards support qualification in FDA 21 CFR Part 211 and Part 820 environments.
Can temperature data be exported digitally?

The unit outputs thermal printouts only; however, optional RS-485 connectivity enables real-time data streaming to external EMS platforms via Modbus RTU protocol.
What is the validation support package?

Jihepu provides IQ/OQ protocol templates, factory-as-tested temperature mapping reports, and calibration certificates traceable to NIM (National Institute of Metrology, China).
Does it meet WHO PQS requirements for vaccine storage?

Yes—the unit satisfies WHO PQS SSV-01:2022 criteria for stability, uniformity, and recovery time under tropical ambient conditions (30°C/70% RH).
What is the expected service life under continuous operation?

Rated for 15,000 operating hours (≈12 years at 24/7 duty cycle), with compressor and controller covered under extended 3-year parts warranty.
