Stability, safety, and efficiency: the LKv 3910 serving healthcare professionals
The Liebherr MediLine LKv 3910 is a refrigeration unit specifically designed for professional environments where temperature consistency, operational reliability, and the security of stored products are top priorities. Designed for laboratory use, this model combines compactness and performance. Its net capacity of 344 liters is optimized by a functional internal layout, featuring five height-adjustable, plastic-coated shelves, each capable of supporting up to 45 kg. These shelves allow for flexible and secure organization of stored contents.
The temperature range, adjustable from +3°C to +16°C, is maintained by a dynamic cooling system paired with precise electronic control. Monitoring is carried out via a clear digital display, allowing fine-tuned adjustments to within a tenth of a degree. This precision is further enhanced by a single-point calibration function, enabling compensation for discrepancies between the set and actual internal temperatures.
The LKv 3910 is equipped with a full set of safety systems essential in sensitive environments. A visual and audible alarm is triggered in the event of temperature deviation, power failure, or if the door is left open. When power is restored, a dedicated alert notifies the user. These systems are reinforced by a volt-free contact for connection to an external alarm system and an RS 485 interface for centralized documentation.
The construction of the LKv 3910 relies on robust materials. The inner chamber is made of white thermoformed ABS, facilitating easy cleaning and ensuring excellent resistance to chemical substances. The external housing is made of white painted steel, while the solid door—also steel—is reversible and equipped with a security lock. An automatic door-closing mechanism is integrated, limiting accidental thermal loss.
With a noise level of just 48 dB(A), this model operates quietly and fits seamlessly into laboratories and medical facilities. Its annual energy consumption of only 309 kWh makes it an energy-efficient appliance, well-suited for continuous use in demanding settings.
The refrigerator is tested according to ISO 60068-3 standards, ensuring maximum temperature stability and uniformity, even during automatic defrost cycles.
