Key Features
-
ATEX-Certified Spark-Free Interior: Complies with EN/IEC 60079-0, EN/IEC 60079-7, and EU Directive 2014/34/EU (ATEX), with an interior rated II 3 G Ex ec IIC T6 (Zone 22), ensuring safe storage of flammable substances in closed containers.
-
Precise Temperature Stability: Guarantees minimal temperature fluctuation of ±5°C, protecting sensitive materials, with a +2°C SafetyDevice to stabilize temperature and activate alarms if it falls below +2°C due to malfunction.
-
SmartFrost Technology: Reduces frost build-up on interior walls and stored products, minimizing defrosting frequency, with smooth, easy-to-clean walls and an evaporator embedded in foam insulation for energy efficiency and even cooling.
-
Energy Efficiency: Consumes 384 kWh/year using eco-friendly R290 refrigerant and efficient compressors, delivering low operating costs and a low global warming potential.
-
Hygienic Design: Seamless, one-piece polystyrene inner liner is robust, odorless, and fully recyclable, with large corner radii for quick and easy cleaning, meeting ISO EN 14644-1 Class 5 cleanroom standards.
-
Advanced Monitoring: Features a touch-screen controller with built-in data logger, min./max. temperature log, and power failure info, plus optional SmartMonitoring via retrofittable WiFi/LAN interface for cloud-based temperature documentation and alarms.
-
Safety and Security: Includes a mechanical lock with two keys, visual/audible alarms, volt-free alarm contact, and an antimicrobial handle with opening mechanism for hygiene and unauthorized access prevention.
-
Flexible Configuration: Reversible door hinges (factory-set to right), adjustable shelves (5 glass shelves, 40kg load each) or optional drawers (6), and a feedthrough for external sensors enhance installation and usability.
-
User-Friendly Controls: Flush-integrated control panel with self-explanatory menu and three touch buttons allows status readout without opening the door, with a hidden service menu for custom settings like alarm sound and defrost adjustments.
-
Low Maintenance: Operates without filters or replaceable components, with replaceable plug-in door seals for easy maintenance, and a self-closing door (<90°) for convenience.
