Key Features
-
ATEX 95 Spark-Free Interior: Certified to EN/IEC 60068-3, EN/IEC 61010-1, EN/IEC 61010-2-011, and EU Directive 2014/34/EU (ATEX), with an interior rated for Zone 22 (II 3 G Ex ec IIC T6), ensuring safe storage of flammable substances in closed containers that could form explosive atmospheres.
-
Precise Temperature Stability: Maintains a maximum temperature fluctuation of ±3°C, tested to EN 60068-3 standards by measuring temperature at nine points in the interior, ensuring optimal protection for sensitive materials.
-
Fan-Assisted Cooling: Forced-air cooling system with high-efficiency fans cools freshly stored items rapidly and maintains uniform temperature distribution, eliminating hot and cold spots; automatic defrost enhances efficiency and reduces maintenance.
-
Energy Efficiency: Consumes 421 kWh/year (1.153 kWh/24h) using eco-friendly R600a refrigerant and high-efficiency compressors, minimizing operating costs and environmental impact with low global warming potential.
-
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 4 cleanroom and GMP Class A standards for minimal particulate contamination.
-
Advanced Monitoring: 2.4″ touch-screen controller with built-in data logger, min./max. temperature log, and HACCP-compliant documentation; optional SmartMonitoring via retrofittable WiFi/LAN interface for cloud-based temperature monitoring and alarms.
-
Safety and Security: Features a mechanical lock with two keys, visual/audible alarms for temperature deviations, power failure, and sensor defects, volt-free alarm contact for external systems, +2°C SafetyDevice to prevent freezing, and an alarm test function for system reliability.
-
Flexible Configuration: Reversible door hinges (factory-set to right) without additional parts, 5 adjustable glass shelves (40kg load each), and a Ø10mm feedthrough for external sensors for installation flexibility.
-
User-Friendly Controls: Flush-integrated control panel with a dirt-resistant membrane keyboard, self-explanatory menu with three touch buttons, demo mode for training, and support for 19 languages; displays serial and service numbers for easy access.
-
Low Maintenance: Operates without filters, with automatic defrost 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 49 dB(A).
