Laboratory freezer SFTfg 1501 Performance

undercounterexplosion-proofair-cooled

Overview
ATEX-compliant undercounter freezer for laboratories designed for the safe storage of closed containers with combustible or potentially explosive substances. Provides reliable temperature stability, reduced interior frost build-up (SmartFrost) and multiple safety and monitoring interfaces for professional lab environments.

Key highlights

• ATEX classification: interior certified <Ex> II 3 G Ex ec IIC T6 (Zone 22) for storage of combustible substances in closed containers.
• SmartFrost technology: significantly reduces frost formation inside the cabinet; evaporator embedded in foam for even cooling and improved energy efficiency.
• Temperature stability ±5 °C (operational reference): minimal fluctuations to protect thermosensitive contents.
• Retrofit WLAN/LAN interface and SmartModule compatibility: enables SmartMonitoring for remote monitoring and documentation.
• Designed for long service life: high-quality materials, solid workmanship and extended spare-part availability.
• Easy-to-clean interior: seamless polystyrene inner container with large radii for quick cleaning and hygiene.
• Alarm relay and alarm functions: optical and acoustic alarm outputs and potential-free contact for building management systems.
• Mechanical lock: secure storage with mechanical lock and two keys.

Additional features

• Antibacterial lever handle: lever handle with antimicrobial properties to reduce bacterial load.
• Intuitive control: door-integrated control panel with symbols and voice guidance; operable via buttons or Touch & Swipe, including with gloves.
• Interchangeable door hinge: delivered with right-hand hinge; convertible to left-hand by the user without additional parts.
• Replaceable door seal: plug-in door seals that can be replaced without tools.
• Evaporator cover: prevents contact of stored items with cold surfaces and improves temperature stability.
• Min./max. temperature recording and SmartMonitoring-enabled: temperature history and compatibility with connectivity solutions.
• Power-failure info: reports maximum temperature reached during power interruptions upon power restoration.
