Liebherr Mediline high performance lab refrigerators feature advanced electronic controls, top mounted compressors and alarm monitoring. Maximum temperature stability in the interior is ensured by the dynamic cooling system with double ventilation. Sturdy and versatile, the shelves are easily height-adjustable so that products can be stored optimally on the plastic-coated grid shelves. The interior is made of high-quality stainless steel, which is easy to clean thanks to the large corner radii, for additional hygienic requirements. A very short defrost cycles allow the internal temperature to be kept almost constant during the cycle. All laboratory appliances are designed according to the EN 60068-3 standard with regard to maximum temperature stability and consistency. A visual and audible alarm alerts the user of temperature deviations and also alerts if the door is open for longer than one minute or in the event of a power failure. An integrated data-memory logs the last three temperature alarms and power failures, recording time, date and duration of the alarm. These units are also equipped with a volt-free contact for alarm forwarding to an external remote warning system. Laboratory appliances with an electronic controls include a 1-point calibration function for accurate temperature control. This allows for compensation between the set temperature and the actual internal temperature. Positive or negative changes to the correction value can be made in steps of 0.1 K.
