Liebherr SmartMonitoring is a comprehensive solution for documenting and monitoring measurement and operating data, alarm messages and device states. The SmartCoolingHub required for this can be directly connected to this device via the available RS 485 interface. The alarm testing allows you to check whether the alarm system is functioning properly (no matter if it is internal or external). The test has no effect on the performance of the refrigerator. DIN is the acronym for Deutsches Institut für Normung (German Institute for Standardization). The specialists from this institute define the standards applicable in the industry. The DIN 58345 standard applies to pharmaceutical coolers, which can be used to store drugs at a temperature of + 2 ° C to + 8 ° C. The DIN 58345 standard reflects the latest technological developments and clearly defines the requirements that must be met by pharmaceutical refrigerators. The inside temperature shown on the digital display is rounded to the nearest degree and can be read from the outside without any problems. This eliminates the need to open the appliance. Highly efficient fans cool freshly inserted food quickly and keep the temperature constant throughout the interior. Liebherr has been acquiring experience and research and development in the field of cooling for decades, guaranteeing the highest quality equipment refrigeration. By using only the highest class compressors, condensers, evaporators and other components of the cooling system, Liebherr creates energy-saving devices with low operating costs.
