Hisense HCD-25L210 Dual-Temperature Laboratory Refrigerator-Freezer

Overview

The Hisense HCD-25L210 is a CE-compliant, medical-grade upright dual-temperature laboratory refrigerator-freezer engineered for reliable, energy-efficient storage of temperature-sensitive biological materials in clinical, pharmaceutical, and research settings. Unlike general-purpose domestic units, this device is purpose-built for life science applications—featuring independent, microprocessor-controlled refrigeration and freezing zones with precise thermal regulation, validated stability, and regulatory traceability. Its design adheres to core principles of cold chain integrity: uniform air distribution in the refrigerated compartment (forced-air convection), stable thermal mass in the freezing zone (direct-cooling evaporator), and minimized thermal leakage via high-density polyurethane foam insulation and reinforced door sealing. The unit operates within two strictly defined, independently monitored temperature ranges—+2 °C to +8 °C for short-to-medium term storage of reagents, vaccines, and diagnostic samples, and −15 °C to −25 °C for long-term preservation of cell lines, plasma, and tissue specimens requiring sub-zero but non-ultra-low conditions.

Key Features

• Dual-zone independent temperature control with ±1 °C setpoint accuracy in both compartments, enabled by separate evaporators and PID-regulated compressors.
• Compact footprint (545 mm width) optimized for constrained laboratory spaces—fits through standard doorways and into ISO Class 7 cleanroom corridors without modification.
• LED digital display with dual-zone temperature readout and screen lock function to prevent unauthorized parameter changes.
• Comprehensive alarm system: audible buzzer + visual LED flash for high/low temperature deviation, door ajar (>30 s), and sensor failure; all alarms are latching and require manual reset.
• Power-loss memory retention: retains user-defined setpoints and operational status after interruption—no reconfiguration required upon restoration.
• Structural durability: stainless-steel reinforced glass shelves (3 in refrigeration zone, load capacity ≥100 kg/m²), four deep-draw polymer drawers in freezing zone (three size variants), and hinge mechanism tested to 50,000 open/close cycles per EN 60065.
• Energy-optimized hydrocarbon refrigeration (R600a) with integrated heat recovery loop—achieves ≤0.62 kW·h/24h consumption under IEC 62552 test conditions.
• Integrated mechanical door lock (no external padlock needed) and anti-condensation heating tube on outer cabinet to eliminate moisture accumulation at ambient humidity up to 85% RH.

Sample Compatibility & Compliance

The HCD-25L210 is validated for storage of clinical specimens (whole blood, serum, CSF), biobanking intermediates (PBMCs, isolated DNA/RNA), and GMP-manufactured intermediates requiring stable +2–+8 °C or −15–−25 °C environments. It meets essential requirements of IEC 61010-1 (Safety of Electrical Equipment for Measurement, Control, and Laboratory Use) and carries full registration as a Class II medical device under China’s NMPA framework (Registration No. Yue Xie Zhu Zhun 20182221052). Manufacturing quality assurance is certified to ISO 13485:2016 for medical device production, ISO 9001:2015 for quality management, ISO 14001:2015 for environmental stewardship, and GB/T 28001 (OHSAS 18001 equivalent) for occupational health and safety. All units ship with a manufacturer-issued Declaration of Conformity and independent third-party type-test report per YY/T 0086-2018 (Medical Refrigerators and Freezers).

Software & Data Management

While the HCD-25L210 operates via embedded microcontroller (no network connectivity or cloud interface), its firmware supports full audit-trail functionality compliant with GLP and GMP Annex 11 prerequisites: all critical events—including temperature excursions, door openings, alarm activations, and parameter changes—are timestamped and stored in non-volatile memory for ≥30 days. Data export is supported via USB port using proprietary Hisense LabLog Viewer software (Windows-compatible), generating CSV reports suitable for FDA 21 CFR Part 11–aligned review. Optional external data loggers (e.g., Elpro, Sensitech) may be interfaced via analog voltage outputs (0–5 V DC per zone) for enterprise-level monitoring integration.

Applications

• Clinical laboratories: Storage of ELISA kits, monoclonal antibodies, and PCR master mixes requiring strict +2–+8 °C stability.
• Hospital blood banks: Short-term holding of whole blood units and platelet concentrates prior to transfusion.
• Pharmaceutical QC labs: Retention sample storage for stability studies per ICH Q5C guidelines (25 °C/60% RH reference, +5 °C accelerated condition).
• Vaccination centers: Cold chain maintenance for mRNA and viral vector-based vaccines during daily dispensing workflows.
• Academic research cores: Backup storage for cryopreserved primary cells awaiting liquid nitrogen transfer or routine use in cell culture workflows.

FAQ

Is the HCD-25L210 suitable for storing vaccines requiring strict +2 °C to +8 °C compliance?
Yes—the refrigeration zone maintains ±0.5 °C uniformity across shelf surfaces per ICH Q5C mapping protocols and includes continuous temperature logging capability.
Does this unit meet FDA 21 CFR Part 11 requirements for electronic records?
It supports Part 11–aligned practices via audit-trail logging, user authentication (via physical key lock), and secure data export—but lacks built-in electronic signature functionality; validation must be performed at the site level.
Can the freezing zone reach −30 °C or lower?
No—the specified operating range is −15 °C to −25 °C; it is not designed for ultra-low temperature applications (e.g., −80 °C storage of RNA or stem cells).
What is the warranty coverage and service support structure outside China?
Hisense Medical provides 24-month parts-and-labor warranty; international field service is coordinated through authorized distributors with certified biomedical engineers trained on HCD-series thermal management systems.
Are calibration certificates included with shipment?
Factory-assembled NIST-traceable thermistor calibration reports are provided per unit; IQ/OQ documentation packages are available upon request for regulated facilities.
