Laboratory freezers with spark-free interior. Laboratories place high demands on the storage of sensitive substances. This laboratory fridge is the ideal choice: it guarantees powerful refrigeration at constant temperatures – and the best energy efficiency.

• Minimal temperature fluctuation of no more than ±5°C.
• Conforms to EN/IEC 60079-0 or EN-IEC 60079-7 and complies with EU Directive 2014/34/EU (""ATEX Directive""). Classification of the interior to Ex> II 3 G Ex ec IIC T6 (declared as Zone 22) makes them suitable for flammable substances in closed containers that could form explosive atmospheres.
• SmartFrost reduces frost build-up in the interior and on stored products. Defrosting is required less often – and when it is necessary, it is made much easier by the smooth, easy-to-clean interior walls. The evaporator in the foam insulation ensures high levels of energy efficiency as well as even cooling.
• With the retrofittable WiFi and LAN interface, appliances can be effortlessly connected to external systems, such as SmartMonitoring.
• Equipped with a mechanical lock with two keys for the storage of temperature-sensitive products.
• The plastic inside container is made of polystyrene: a fully recyclable, robust, and odourless plastic. Manufactured seamlessly from one piece, it has no hidden dirt traps and the large corner radii can be cleaned quickly and easily. The perfect combination of sustainability and hygiene.
• In the event of an alarm, the responsible control centre is informed immediately, usually through connection to the building control system. You can define in advance which alarms are to be forwarded, as well as set how long the forwarding remains active and whether a reminder should be sent after the alarm acknowledgement. This allows you to react immediately in critical situations.
• The alarm test can be used to check the functionality of the internal and possibly an externally connected alarm device. The cooling of the appliance is not interrupted during the test run.
• The easy-turn handle mechanism makes opening the door effortless. It contains special antimicrobial substances that reduce bacteria by up to 99.99% (according to ISO 22196:2011). Regular and time-consuming disinfection is not necessary. This means the appliance is extremely safe even if many people have access to it.
• Due to operational requirements and application-specific conditions, it is possible to deviate the temperature of the interior from the set temperature to a storage temperature determined with calibrated thermometers. These deviations can be adjusted by the calibration function. For the secure feeling of cooling at precise temperatures.
• Interchangeable door hinge
• Tested for use in cleanrooms in accordance with DIN EN ISO 14644.
• Serial and service number as well as the model designation on the display, where it can be easily read.
• Hidden service menu allows individual configuration of the appliance, such as alarm sound on/off, adjustment of target value ranges or changes to automatic defrosting.
• Convenience at your fingertips: Check the appliance status from the control panel integrated flush in the door without needing to open the door. The menu guidance is self-explanatory and can be operated via symbols and voice control in up to 12 different languages. The display can also be controlled by three touch buttons or with Touch & Swipe, even when wearing gloves.
