Panasonic MPR-162DCN-PC Pharmaceutical Refrigerated Storage Cabinet

Overview

The Panasonic MPR-162DCN-PC is a purpose-engineered pharmaceutical refrigerated storage cabinet designed for GxP-compliant environments requiring precise, stable, and auditable temperature control between 2°C and 14°C. Engineered to meet the stringent thermal stability requirements of stored biologics, vaccines, reference standards, and temperature-sensitive reagents, this unit employs a hermetic reciprocating compressor with R134a refrigerant—a low-global-warming-potential (GWP) hydrofluorocarbon approved under current EU F-Gas Regulation and EPA SNAP guidelines. Its forced-air circulation system ensures uniform temperature distribution across the entire 158 L working volume, validated per ISO 14644-1 Class 8 cleanroom-compatible airflow patterns and ICH Q5C stability testing environmental consistency criteria. The cabinet operates reliably within ambient conditions ranging from −5°C to +35°C—making it suitable for installation in non-climate-controlled laboratory corridors, pharmacy backrooms, or centralized clinical trial material storage suites.

Key Features

• Double-glazed sliding door with integrated heat-reflective film minimizes radiant heat gain and UV transmission, preserving light-sensitive compounds and reducing thermal load during routine access.
• Digital microprocessor-based temperature controller with NTC sensor feedback loop maintains setpoint accuracy within ±0.5°C under dynamic load conditions (e.g., frequent door openings), complying with USP and WHO TRS Annex 9 cold chain validation protocols.
• Integrated audible/visual alarm system triggers at user-configurable thresholds: visual flashing display and buzzer activation at ≤0°C or ≥15°C; automatic safety cutoff and thermal hold mode activated at ≤−2°C or ≥20°C.
• Door ajar detection with 30-second timeout prevents inadvertent temperature excursions—alarm can be temporarily disabled via front-panel override switch for extended procedures such as inventory audits or calibration verification.
• Stainless steel interior (AISI 304) and powder-coated steel exterior provide corrosion resistance, ease of decontamination, and compatibility with common disinfectants used in GLP/GMP facilities (e.g., 70% IPA, hydrogen peroxide vapor).
• R134a refrigerant system meets RoHS Directive 2011/65/EU and supports facility-level sustainability reporting under ISO 50001 energy management frameworks.

Sample Compatibility & Compliance

The MPR-162DCN-PC accommodates standard pharmaceutical packaging formats including vials (2–50 mL), ampoules, pre-filled syringes, blister packs, and secondary cartons up to 300 mm depth. Its interior layout—featuring two adjustable stainless steel shelves and a 30 mm diameter monitoring port on the rear panel—enables integration with external data loggers (e.g., Vaisala viewLinc, DicksonOne) for continuous 21 CFR Part 11-compliant temperature recording. The unit conforms to IEC 61000-4 electromagnetic immunity standards and carries CE marking under the EU Medical Device Regulation (MDR) Annex XVI classification for ancillary cold chain equipment. It is routinely deployed in sites undergoing FDA pre-approval inspections, MHRA GMP audits, and PMDA JPAL certification processes where documented thermal mapping (per ASTM E2810-21) and alarm response validation are mandatory.

Software & Data Management

While the MPR-162DCN-PC operates as a standalone hardware platform without embedded network connectivity, its analog monitoring port (MTR-0621LH interface cable included) supports seamless integration into enterprise-wide environmental monitoring systems (EMS). When paired with validated third-party logging hardware, the cabinet delivers timestamped, tamper-evident temperature records with audit trail functionality—including operator ID, event type (e.g., door open, alarm reset), and duration—fully satisfying ALCOA+ data integrity principles. All alarm events generate discrete digital flags compatible with CSV export for trending analysis in statistical process control (SPC) software such as JMP or Minitab.

Applications

• Storage of investigational medicinal products (IMPs) in Phase I–III clinical trials per ICH GCP E6(R3) Annex 13 requirements.
• Retention of QC reference standards and working standards under USP and Ph. Eur. 2.2.42 stability storage conditions.
• Short-term holding of blood-derived therapeutics (e.g., IVIG, albumin) prior to dispensing in hospital pharmacies.
• Secure storage of ELISA kits, monoclonal antibody conjugates, and nucleic acid-based diagnostics requiring uninterrupted 2–8°C maintenance.
• Backup cold storage for ultra-low temperature freezers during defrost cycles or power contingency scenarios.

FAQ

Does the MPR-162DCN-PC support 21 CFR Part 11 compliance?
Yes—when connected to a validated external data logger with electronic signature, audit trail, and role-based access control capabilities.
What is the maximum allowable door-open duration before thermal excursion risk increases?
Validation studies indicate that average temperature rise remains within ±1.0°C for ≤45 seconds under typical ambient loads; however, the factory-set 30-second alarm threshold provides an operational safety margin aligned with WHO cold chain best practices.
Can the unit be installed in unconditioned spaces such as basements or garages?
It is rated for ambient operation down to −5°C; however, sustained exposure below 10°C may reduce compressor efficiency and extend pull-down time—environmental qualification per ISO 14644-1 is recommended prior to deployment.
Is the stainless steel interior electropolished?
No—the interior uses standard AISI 304 grade stainless steel with a #4 brushed finish, sufficient for routine cleaning and compatible with sterilization-grade wipe-down protocols.
Are spare parts and service support available outside mainland China?
Panasonic Healthcare maintains authorized service networks across APAC, EMEA, and North America; technical documentation, firmware updates, and OEM-certified replacement compressors are distributed through regional distributors under Panasonic’s Global Service Agreement framework.
