Hisense HC-5L360 Laboratory Refrigerator (2–8°C)

Overview

The Hisense HC-5L360 Laboratory Refrigerator is a purpose-engineered 2–8°C cold storage unit designed for reliable, compliant short- to medium-term preservation of temperature-sensitive biological and pharmaceutical materials. Built on a robust refrigeration architecture featuring a high-efficiency, CFC-free refrigerant cycle and an internationally sourced hermetic compressor, the HC-5L360 maintains stable thermal conditions within ±0.5°C setpoint deviation under standard ambient loads (25°C, 60% RH). Its forced-air circulation system—integrated with finned evaporator technology—ensures uniform temperature distribution across the full 360 L working volume, minimizing vertical and horizontal gradients to meet ISO 14644-1 Class 8 cleanroom-compatible operation requirements. The unit complies with core design principles referenced in WHO Technical Report Series No. 961 (Annex 9), USP , and EU GDP Annex 9 for medicinal product storage, making it suitable for use in clinical laboratories, hospital pharmacy departments, vaccine distribution hubs, and QC/QA facilities operating under GLP or GMP frameworks.

Key Features

• Microprocessor-based temperature control system with real-time LED display of internal temperature and relative humidity (±3% RH stability)
• Dual-layer tempered glass door with LOW-E coating—prevents condensation formation at 25°C/80% RH ambient conditions
• Seven independent alarm modes: high/low temperature, door-open, sensor fault, mains power loss, low backup battery, and optional remote notification via dry-contact relay or RS485 interface
• 48-hour sustained alarm capability during power interruption, powered by internal rechargeable backup battery
• HIPS polymer interior lining—chemically resistant to common laboratory disinfectants (e.g., 70% ethanol, 0.5% sodium hypochlorite) and impact-durable per ASTM D790
• Five fully adjustable, label-ready wire shelving tiers—each rated for 25 kg static load and independently positionable without tools
• Omnidirectional locking casters enabling safe relocation within regulated lab spaces while maintaining ISO 554-compliant floor contact integrity
• Standard 12 mm diameter test port located on rear panel—facilitates integration with third-party temperature mapping probes or continuous monitoring systems (e.g., Vaisala, Sensitech)
• Wide-input voltage tolerance (187–242 V AC) ensures operational continuity in regions with unstable grid infrastructure

Sample Compatibility & Compliance

The HC-5L360 supports storage of pharmacopeial-grade reference standards, lyophilized reagents, monoclonal antibodies, diagnostic kits, and live-attenuated vaccines requiring uninterrupted 2–8°C exposure. Its chamber geometry and airflow profile have been validated to maintain ICH Q5C stability zone compliance over 72-hour door-open challenge tests (per WHO TRS 961 Annex 9 methodology). All electrical components conform to IEC 61010-1:2010 safety standards for laboratory equipment. While the base unit does not include factory-installed data logging, its analog voltage output (0–5 V DC proportional to chamber temperature) and digital alarm relay outputs are compatible with externally validated environmental monitoring systems (EMS) that satisfy FDA 21 CFR Part 11 electronic record requirements—including audit trail generation, user access controls, and electronic signature support.

Software & Data Management

The HC-5L360 operates as a standalone hardware platform with embedded firmware controlling thermal regulation and alarm logic. It does not include proprietary cloud software or built-in data logging memory. However, its analog temperature output signal and discrete alarm relay contacts enable seamless integration into enterprise-wide EMS platforms such as DicksonOne, Monnit, or TempTale® Ultra. When connected to a validated external data logger with configurable sampling intervals (e.g., 2-minute intervals), the system supports automated CSV export, email/SMS alerting, and PDF report generation compliant with ALCOA+ data integrity principles. Optional RS485 Modbus RTU interface (available upon request) allows centralized polling of temperature, humidity, and alarm status across multi-unit installations—supporting scalable deployment in hospital central pharmacy or contract manufacturing organization (CMO) cold chain operations.

Applications

• Hospital pharmacy cold chain management for insulin, heparin, and biologic injectables
• Vaccine storage in public health clinics and immunization centers aligned with CDC Vaccine Storage and Handling Toolkit guidelines
• QC sample holding for pharmaceutical stability studies (ICH Q1A–Q1E)
• Short-term storage of ELISA kits, PCR master mixes, and cell culture media prior to assay execution
• Biobank specimen staging prior to cryogenic transfer or nucleic acid extraction workflows
• Regulated storage of reference standards used in HPLC and GC calibration protocols
• On-site cold storage for mobile clinical trial units and decentralized research sites

FAQ

Does the HC-5L360 comply with FDA 21 CFR Part 11?
The unit itself is not Part 11–certified, but its analog/digital interfaces support integration with validated third-party EMS platforms that provide full Part 11 compliance—including electronic signatures, audit trails, and role-based access control.
Can temperature mapping be performed inside the chamber?
Yes—the standard 12 mm test port permits insertion of calibrated thermocouples or wireless loggers for IQ/OQ/PQ validation per ISO 14644-3 and ISPE Good Practice Guide for Cold Chain Equipment Qualification.
Is the interior lighting dimmable or controllable remotely?
LED interior lighting is manually switched on/off via front-panel button; no remote or scheduled control functionality is provided.
What is the maximum allowable ambient operating temperature?
Rated performance is guaranteed at ambient conditions up to 32°C and 60% RH per IEC 60068-2-1/2 environmental testing standards.
Are spare shelves and door gaskets available as service parts?
Yes—HIPS shelves (part #HC-SH360-5), magnetic door gaskets (part #HC-GSKT-360), and replacement LOW-E glass panels (part #HC-GLASS-360) are stocked and supplied under Hisense’s global service agreement program.
