HYC-610 Medical Refrigerator (2–8°C)

Overview

The HYC-610 Medical Refrigerator is a CE-marked, NMPA-registered Class II medical device engineered for stable, compliant cold-chain storage of temperature-sensitive biologicals, vaccines, reagents, and clinical specimens at precisely controlled conditions between 2 °C and 8 °C. Designed in accordance with YY/T 0086–2018 (Chinese standard for medical refrigeration equipment) and aligned with ISO 13485 quality management principles, the unit employs forced-air circulation and multi-point thermal sensing to maintain uniform internal temperature distribution—critical for preserving potency, sterility, and assay integrity across regulated life science workflows. Its hermetically sealed compressor, CFC-free refrigerant blend, and high-density polyurethane insulation ensure energy-efficient operation while minimizing environmental impact and thermal drift under variable ambient loads (Climate Class T: rated for ambient temperatures up to 43 °C).

Key Features

• Microprocessor-controlled digital temperature management with ±0.5 °C uniformity (measured at 9 locations per IEC 60068-3-5) and 0.1 °C setpoint resolution.
• Forced-air cooling system with dual-speed fan modulation ensures rapid recovery (<30 min) after door openings and eliminates hot/cold spots across the 608 L chamber.
• Five-tier alarm architecture: independent detection and audible/visual alerts for high/low temperature excursions, power interruption, door-open duration >30 s, NTC sensor failure, and low backup battery voltage.
• Remote alarm interface via dry-contact relay output (NO/NC configurable), compatible with building management systems (BMS) and centralized lab monitoring platforms.
• Stainless steel (AISI 304) interior with seamless welds and rounded corners for ease of cleaning and compliance with ISO 14644-1 cleanroom-compatible maintenance protocols.
• Adjustable epoxy-coated shelving system—fully removable, repositionable, and labeled with integrated tag slots—supports heterogeneous sample containers from 2 mL vials to 500 mL bottles without load restriction compromise.
• Mechanical door lock with tamper-resistant latch meets CLIA and CAP requirements for restricted-access specimen storage; optional padlock compatibility available.

Sample Compatibility & Compliance

The HYC-610 accommodates primary and secondary packaging formats used in diagnostic, pharmaceutical, and clinical trial logistics—including vaccine carriers (e.g., WHO-prequalified cold boxes), PCR master mix kits, monoclonal antibody formulations, and EDTA-plasma tubes. Its validated temperature stability profile supports adherence to USP , EU Annex 15, and WHO Technical Report Series No. 961 (2011) for cold chain integrity. The unit includes a dedicated 6 mm diameter temperature probe port for third-party validation hardware (e.g., Vaisala, DicksonLog), enabling IQ/OQ/PQ execution under GxP environments. All firmware logic complies with FDA 21 CFR Part 11 requirements when paired with the optional GLP-compliant USB data logger (model HYL-USB-LOG), which provides time-stamped, encrypted, audit-trail-enabled temperature records.

Software & Data Management

While the HYC-610 operates via embedded microcontroller without cloud connectivity, its architecture supports full traceability through optional peripheral integration. The HYL-USB-LOG module records temperature at user-defined intervals (1–60 min), stores ≥12 months of data locally, and exports CSV files compatible with LIMS (e.g., LabVantage, Thermo Fisher SampleManager) and electronic lab notebooks (ELNs). Password-protected LED interface prevents unauthorized parameter modification—consistent with ALCOA+ data integrity principles. Firmware updates are performed offline via secure USB key, ensuring cybersecurity compliance in air-gapped laboratory networks.

Applications

• Vaccine storage in hospital pharmacies and public health centers (aligned with CDC Vaccine Storage and Handling Toolkit guidelines).
• Short-term holding of QC reference standards and calibrators in ISO/IEC 17025-accredited testing laboratories.
• Pre-analytical stabilization of whole blood, serum, and CSF samples prior to centrifugation or transport to central labs.
• Storage of enzyme-conjugated reagents, ELISA kits, and molecular probes requiring strict thermal history control.
• Backup refrigeration for biosafety level 2 (BSL-2) containment areas where redundancy is mandated by institutional biosafety committees.

FAQ

Does the HYC-610 meet international regulatory requirements for vaccine storage?
Yes—it satisfies WHO PQS criteria for performance, complies with YY/T 0086–2018, and is registered with China’s NMPA as a Class II medical device. Validation documentation supports alignment with CDC and ECDC cold chain specifications.
Can temperature data be exported for audit purposes?
Yes—when equipped with the optional HYL-USB-LOG module, the unit generates time-stamped, tamper-evident CSV logs meeting GLP and 21 CFR Part 11 record retention standards.
Is remote monitoring supported out of the box?
The base unit includes a dry-contact alarm relay for integration into existing facility alarm systems; Ethernet or Wi-Fi telemetry requires external gateway hardware and is not natively embedded.
What is the maximum allowable ambient temperature for continuous operation?
Rated for Climate Class T (Tropical), the HYC-610 maintains specified performance at ambient temperatures up to 43 °C, provided ventilation clearances (100 mm rear/side, 200 mm top) are observed.
Are calibration certificates included with shipment?
Factory calibration reports (traceable to NIM, China) are supplied; on-site IQ/OQ services and third-party metrology certification are available through authorized service partners.
