Liebherr professional appliance for demanding applications.
The Liebherr MediLine 3910 is specially designed as a professional cooling unit for commercial use in laboratories with a small to medium footprint. Despite its size, the efficient cooling system has atemperature operating range of +3 °C to +16 °C. This temperature range is subject to the DIN 58345 standard, which is currently the highest possible state of the art standard that reflects the precisely defined requirements regarding medication cooling systems.
In the event that the maximum temperature of 8 °C is exceeded or the permissible minimum temperature of 2 °C is not reached, an optical-acoustic alarm is triggered immediately. The device also has a power failure alarm and numerous other extras, which we have summarized for you here.
About the test procedure according to EN 60069-3
In order to maintain temperature accuracy on a permanent basis, all Liebherr cooling systems are tested according to the EN 60069-3 test procedure. This involves measuring the temperature stability at nine different points inside the units. The digital temperature display on the outside of the appliance also shows you the internal temperature and any changes, accurate to the degree.
The model's built-in professional electronics and its dynamic cooling system ensure a particularly high level ofsafety and temperature consistency. Among other things, highly efficient fans ensure rapid cooling of newly stored goods.
The noise level of the unit is 48 dB(A) in normal operation. This enables trouble-free operation under quiet conditions.
High-quality design & functionality
The high-quality workmanship of the cooling system contributes to the fact that all components and their coordination with each other ensure the longest possible service life and ease of operation in the professional sector. This benefits both you as a customer and the environment.
In particular, theseamless plastic interior containershelp to prevent hard-to-remove contaminants from accumulating in the corners and edges. Six shelves and bins are available, five of which are adjustable. The material of the shelves consists of grates, which are plastic-coated and can each be loaded with up to forty-five kg.
The installed compressors, condensers, evaporators of the latest generation help to significantly reduce operating costs. The energy consumption of the Liebherr MediLine in 24 h in kWh is 0.846.
In addition, a lock with two keys ensures that people without authorization to open do not gain access. The MediLine models are factory-equipped with a door hinge on the right side. However, it is possible to change this without any problems in order to select an installation area that is optimalfor you and allows unrestricted operation.
External connection options
Since professional refrigerators like this model are always responsible for proper storage of preparations, there arevarious connection options on the back of this item, such as an external temperature sensor or a potential-free alarm output. There is also anRS 485 interface connection for central monitoring as well as a potential-free contact that can be used to connect a visual or audible alarm device.
Storage of important data
This unit stores minimum and maximum indoor temperaturesas well as the last three temperature alarms that were triggered, including the time, date and duration of the triggered alarm. Should the power supply fail, these are also documented up to three times by the time, date and duration of the failure.
Alarm test function
To test the functionality of the alarm, the model has a reliable alarm test function. This tests both the internal and external alarm devices. The cooling of the device during this test phase is not interrupted. So you can be sure that your samples, medications or other stored goods will continue to be kept in the best conditions. A visual and audible alarm informs you of any faults in the unit and any unforeseen changes in temperature.
Liebherr SmartMonitoring compatible
This unit is prepared for the popular Liebherr SmartMonitoring system and monitors all relevant environmental parameters. The required interface converter is available as a retrofit kit for the LKv 3910 model. Using thebus interface, you can connect and network up to 20 devices. SmartMonitoring from Liebherr thus helps you to concentrate fully on your work.
If a fault occurs in the cooling system, an alarm is triggered immediately. In order tofully comply with yourquality guidelines, the serial bus interface for the system also takes care of its documentation - so you can quickly call up the data and transmit it to inspectors and authorities if necessary.SmartMonitoring can also be used as a remote monitoring system if you are not on the premises. Optionally, you can be notified of error messages via SMS or e-mail.
The scope of the documentation includes the monitoring of all measurement and operating data of the unit as well as alarm messages and the general device status of the cooling unit. All you need for connection is aSmartCoolingHub, which is connected to the already pre-equipped RS 485 interface. This is available as an accessory if it is not already installed for you at the factory. We will be happy to support you with this.
The dashboard for monitoring your data
The dashboard, which is part of SmartMonitoring, always shows you the current data of your instrument. Samples, substances and chemicals in the cooling system can react negatively to even minor temperature fluctuations and consequently become unusable.
To prevent such problems from arising in the first place, you do not need to rely solely on the model's fault-free operation. The intuitive dashboard provides you with all the necessary data around the clock to protect the contents from damage or spoilage.
Use of environmentally friendly refrigerants
The refrigerants that are in this item are environmentally friendly. This means that they produce only a very small greenhouse effect and have no ozone depletion potential. The refrigerants used areR600a and R 290 .
Technical data at a glance
We would like to give you a brief overview of the most important technical data: the compact model comes with a 360 liter capacity as well as external dimensions of (H/W/D) 184 cm x 60.1 cm x 61.8 cm with a net weight of 66 kg. This makes it easy to transport the unit from A to B in the laboratory, so you can find the most suitable place. The energy consumption in 24 h in kWh is 0.846.
In addition, the model has six shelves for more order in the interior, five of which are adjustable. The grates of the shelves are plastic-coated and can bear loads of up to 60 kg. So you can store both small and large quantities of samples or other stored goods. The material of the inner containers is plastic.
