Liebherr HMFvh 4011 Pharmaceutical Refrigerator (420 L, +5 °C)

Overview

The Liebherr HMFvh 4011 is a high-integrity pharmaceutical refrigerator engineered for compliant, stable, and traceable cold storage of temperature-sensitive biological materials, reference standards, clinical trial samples, and regulated drug substances in GxP environments. Designed and manufactured in Austria by Liebherr-Hausgeräte Obergermatingen GmbH, this unit operates at a precisely maintained +5 °C setpoint—optimized for short- to medium-term storage of vaccines, reagents, antibodies, cell culture media, and other lab-grade biologics requiring refrigerated but non-frozen conditions. Its architecture adheres strictly to DIN 13277, the German standard specifying safety, performance, and functional requirements for laboratory refrigeration equipment. The forced-air cooling system ensures uniform temperature distribution across the entire 297 L net storage volume, while thermal stability—quantified per EN 60068-3—is maintained within ±2.4 °C fluctuation and ±3.0 °C gradient under defined ambient conditions (+25 °C). This level of thermal consistency meets the operational thresholds required for ISO/IEC 17025-accredited laboratories and supports alignment with USP <1089>, EU GDP Annex 9, and FDA guidance on storage condition monitoring.

Key Features

• Electronic temperature control with 2.4-inch color touchscreen interface supporting intuitive parameter adjustment, real-time monitoring, and event history review
• Integrated SafetyDevice function: automatically activates freeze protection if internal temperature drops below +2 °C, preventing sample crystallization or denaturation
• Dual-stage alarm system: visual and audible alerts for power failure (with 12-hour battery-backed continuity), temperature deviation, door ajar, and sensor fault
• Electronic lock with user-configurable PIN code; optional remote control (digital input) enables secure access management without physical key sharing
• Forced-air circulation with optimized airflow path design minimizes vertical and horizontal temperature gradients across all six storage levels
• Energy-optimized architecture: R600a refrigerant, high-efficiency compressor, low-power LED lighting (vertical strip mounted on left wall), and vacuum-insulated door seals reduce annual consumption to 1389 kWh
• Robust mechanical construction: steel outer cabinet (white finish), tempered glass door, commercial-grade molded polystyrene interior lining, and reinforced adjustable wire shelves (plastic-coated, 45 kg load rating)

Sample Compatibility & Compliance

The HMFvh 4011 accommodates standard laboratory containers—including 50 mL conical tubes, 15 mL centrifuge tubes, cryovials (in secondary packaging), multiwell plates, and sealed vials—across its 460 × 423 mm usable shelf area. All internal surfaces are chemically resistant and smooth for decontamination. The unit satisfies DIN 13277 Class II requirements for laboratory refrigerators, including mechanical durability, electrical safety (IEC 61010-1), and electromagnetic compatibility (EN 61326-1). Its integrated data logging and network connectivity support compliance with 21 CFR Part 11 when deployed with validated SmartMonitoring software—enabling audit-trail generation, electronic signatures, and role-based access control. Temperature mapping validation reports can be generated using the built-in USB logger or exported via LAN/WiFi for inclusion in IQ/OQ/PQ documentation packages.

Software & Data Management

Equipped with Liebherr’s SmartModule platform, the HMFvh 4011 supports seamless integration into centralized environmental monitoring systems (EMS). Through its embedded WiFi/LAN interface, users can remotely monitor real-time temperature, alarm status, door events, and power supply integrity via web browser or mobile application. Data is timestamped and stored locally on internal memory (retaining ≥30 days of 1-minute interval readings), with optional export to CSV or PDF formats via USB port. When connected to Liebherr SmartMonitoring server infrastructure, the device supports automated report scheduling, configurable threshold alerts (email/SMS), and long-term trend analysis aligned with GLP/GMP record retention policies. All firmware updates are digitally signed and installed over secure HTTPS connections to maintain system integrity.

Applications

• Storage of temperature-critical pharmaceutical intermediates and final dosage forms in QC/QA laboratories
• Short-term holding of clinical trial biospecimens (serum, plasma, PBMCs) prior to processing or shipment
• Refrigerated staging of calibration standards and reference materials used in analytical method validation
• Secure containment of diagnostic reagents, enzyme conjugates, and monoclonal antibody stocks in IVD development labs
• Backup cold storage for critical inventory during freezer maintenance or cascade failures in ultra-low temperature (ULT) infrastructure
• Compliant sample archiving in biobanks operating under ISO 20387 requirements for biological resource centers

FAQ

Does the HMFvh 4011 meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—when operated with validated Liebherr SmartMonitoring software and configured with audit trail, electronic signature, and role-based access controls, the system supports Part 11 compliance for electronic records and signatures.

Can the unit be installed in a controlled room environment with ambient temperatures up to +35 °C?
Yes—the device is rated for continuous operation within an ambient range of +10 °C to +35 °C and maintains specified thermal stability under those conditions per EN 60068-3 test protocols.

Is temperature mapping validation supported out-of-the-box?
The unit includes calibrated NTC sensors and built-in logging capability; however, formal IQ/OQ temperature mapping requires external calibrated probes and third-party validation software per ISO 14644 or EU GDP Annex 15 guidelines.

What is the warranty coverage and service support structure outside the EU?
Liebherr provides a standard 24-month parts-and-labor warranty; extended service contracts and global technical support are available through authorized Liebherr Life Science Partners, including certified field service engineers trained in GxP-compliant maintenance procedures.
