Liebherr Scientific Freezer SFFvh 5501

The Liebherr Scientific Freezer SFFvh 5501 is a professional, upright laboratory freezer in the Perfection series, engineered for the secure storage of temperature-sensitive materials, such as biological samples, reagents, and pharmaceuticals, in laboratories and research facilities. Offering a 472-liter gross capacity and a temperature range of -9°C to -35°C, this freezer ensures reliable preservation with a maximum temperature fluctuation of ±4.4°C. Featuring fan-assisted cooling with NoFrost technology, LED front lighting, an advanced touch-screen controller, and a hygienic polystyrol liner, the SFFvh 5501 delivers exceptional temperature stability, visibility, and maintenance-free operation. With integrated SmartMonitoring, robust safety features, and compliance with DIN 13277 and ISO Class 6 cleanroom standards, it is an ultra-efficient solution for demanding scientific applications, backed by Liebherr’s 3-year warranty.

Key Features

• Superior Temperature Stability: Maintains a maximum fluctuation of ±4.4°C, tested to EN 60068-3 standards by measuring temperature at nine points in the interior, ensuring optimal protection for sensitive materials.

• NoFrost Fan-Assisted Cooling: Eliminates frost build-up with fan-assisted cooling and needs-based defrosting cycles, capturing moisture to provide ice-free storage, reducing maintenance, and maintaining stable temperatures.

• LED Front Lighting: Energy-efficient LED lighting illuminates drawers for clear visibility, even in low-light environments, allowing quick access and minimizing temperature fluctuations by reducing door-open time.

• Energy Efficiency: Consumes 540 kWh/year (1.478 kWh/24h) using eco-friendly R600a refrigerant and high-efficiency components, reducing operating costs and environmental impact.

• Hygienic Design: Seamless, one-piece polystyrol inner liner is robust, odorless, and fully recyclable, with large corner radii for easy cleaning, meeting ISO EN 14664-1 Class 6 cleanroom standards.

• Advanced Monitoring: 2.4″ touch & swipe color display with integrated data logger, min./max. temperature log, and HACCP-compliant documentation; integrated WiFi/LAN interface for SmartMonitoring, enabling cloud-based temperature monitoring and alarms.

• Safety and Security: Features a mechanical lock with two keys, visual/audible alarms for temperature deviations, power failure (12-hour battery backup), and sensor defects, volt-free alarm contact, +2°C SafetyDevice to prevent over-freezing, password protection, and an antimicrobial handle reducing bacteria by up to 99.99%.

• Flexible Configuration: Reversible door hinges (factory-set to right) without additional parts, 4 adjustable plastic-coated wire shelves (60kg load each), 6 flexible drawers (25kg each), 2 baskets, and a Ø10mm feedthrough for external sensors for enhanced installation flexibility.

• User-Friendly Controls: Flush-integrated control panel with a dirt-resistant touch & swipe interface, self-explanatory menu, demo mode for training, and support for 19 languages; hidden service menu for custom configurations like alarm settings and defrost adjustments.

• Low Maintenance: Operates without filters, with automatic defrost via NoFrost technology and replaceable plug-in door seals for tool-free replacement; self-closing door (<90°) enhances convenience; requires only regular cleaning and calibration; operates quietly at 55 dB(A).

Applications

• Pharmaceutical and Biotech Laboratories: Stores temperature-sensitive pharmaceuticals and reagents with precise temperature control, ensuring compliance with regulatory standards.

• Medical and Biological Research: Preserves specimens, cell cultures, and vaccines with uniform temperature stability for reliable research outcomes.
