Liebherr laboratory freezer with convection cooling SFFvh 4001 Perfection
DIN 13277-compliant
Laboratory and pharmacy refrigerators from Liebherr fulfil all the necessary properties and performance criteria to fully comply with DIN 13277. DIN 13277 describes the requirements and test specifications for refrigerators and freezers used in laboratories and for storing medicines.
Ultra-efficient
Constantly rising electricity prices require energy-efficient refrigerators and freezers. Liebherr fully utilises the savings potential of all components: from the compressor and seal to the lighting and electronics. The ultra-efficient appliances in the Perfection series are the best example of the positive effect this has on your total cost of ownership.
NoFrost technology
With professional laboratory appliances from Liebherr, defrosting is no longer necessary. Any moisture is trapped by the recirculating air cooling system, and demand-controlled defrosting phases remove even the last traces of moisture from the interior - for convenient, safe and ice-free storage.
Integrated WiFi/LAN interface
Connect and go: the appliance can be easily networked with external systems, such as SmartMonitoring from Liebherr, via the integrated WiFi and LAN interface. The digital monitoring solution controls and documents the storage temperature - effortlessly, securely and conveniently via the interface.
Mechanical lock
All professional Liebherr appliances are equipped with a mechanical lock with two keys for storing temperature-sensitive products. This means you can be sure that no unauthorised hands can gain access to your stored goods.
SmartMonitoring: your added security
The digital monitoring solution from Liebherr reliably checks and documents the storage temperature and alerts you immediately in the event of deviations. For maximum safe refrigeration and freezing and optimum protection of your valuable contents.
Environmentally friendly refrigerant
Liebherr appliances are optimised for the best possible energy efficiency and low operating costs. Only the natural and environmentally friendly refrigerants R 600a and R 290 are used. In combination with highly efficient compressors, these are extremely powerful - and with their low global warming potential, they are also future-proof.
Designed for a 15-year service life
Sustainable not only means economical, but also durable. High-quality materials in solid workmanship, paired with at least ten years of manufacturer spare parts availability, make a Liebherr appliance a robust, reliable and extremely long-lasting top performer in demanding everyday working life
Easy to clean interior
The plastic inner container is made of polystyrene, a fully recyclable, robust and odourless plastic. Manufactured seamlessly from a single piece, it has no hidden dirt traps and can be cleaned quickly and easily in large radii. The perfect combination of sustainability and hygiene.
Alarm relay
In the event of an alarm, the relevant control centre is informed immediately, usually via a connection to the building management system. You can specify in advance which alarms are to be forwarded, how long the forwarding remains active and whether a reminder should be sent after the alarm has been acknowledged. This allows you to react immediately in critical situations.
Efficient refrigeration system
Decades of experience in the field of refrigeration technology combined with continuous research enable Liebherr to guarantee the outstanding quality of the refrigeration system. The use of high-quality compressors, condensers, evaporators and other refrigeration components ensures both a significant reduction in energy consumption and a reduction in the operating costs of Liebherr appliances.
Alarm test function
This test run can be used to check the functionality of the internal and any externally connected alarm system. The cooling of the appliance is not interrupted during this test run.
Ten years of manufacturer spare parts availability
Sustainable not only means environmentally friendly and economical, but also durable. To ensure that you can enjoy your Liebherr appliance for a long time, Liebherr guarantees the availability of spare parts for at least ten years. Everything is done in advance to ensure that you do not need any spare parts in the first place.
Height-adjustable feet
With height-adjustable feet as accessories, the appliance height can be adapted to your needs and habits. For example, you can raise your professional appliance to make it easier to clean underneath.
Alarm history
In order to be able to assess the quality of the stored substances, a clear history of any anomalies that have occurred is required. The alarm history records important data from the last ten alarms, such as date, duration or maximum temperature. This means you can leave the check to the facts rather than your memory.
Alarm test
Only an alarm that is triggered is a good alarm. The alarm test can be used to check the functionality of the internal and any externally connected alarm device. The cooling of the appliance is not interrupted during the test run. And you can simulate an emergency at your leisure and rehearse it with your staff.
Antimicrobial handle with opening mechanism
Makes it easy for colleagues and difficult for pathogens: the smooth-running handle can be opened effortlessly thanks to its mechanism. It is also treated with special antimicrobial substances and reduces up to 99.99 % of bacteria (in accordance with ISO 22196:2011). Regular and time-consuming disinfection is no longer necessary. This maximises the safety of daily access to many different hands.
Calibration function
Due to operational requirements and application-specific conditions, deviations from the set temperature to a storage temperature determined with calibrated thermometers are possible in the interior. These deviations can be equalised using the calibration function. For the secure feeling of cooling at precise temperatures.
Interchangeable door hinges
Liebherr appliances are factory-fitted with a right-hand door hinge. The door hinge can be changed to the left without any great effort - and above all without any additional parts. This gives you maximum flexibility in your choice of installation location.
Replaceable door seal
Save time and money: Liebherr's plug-in door seals are easy to replace. If a seal is damaged, you can replace it yourself without any tools.
Suitable for clean rooms
Liebherr refrigerators and freezers in the new Scientific line have been tested for use in cleanrooms in accordance with DIN EN ISO 14644. An additional risk assessment for cleanroom suitability by the customer is therefore no longer necessary. This saves time and money.
Clear device information
Should be there immediately when you need it: all the information about the appliance. That's why every Liebherr has its serial and service number as well as the model designation on the display for easy reading. Annoying searches or even clearing the interior to read the information are a thing of the past.
Demo mode
For training purposes or exhibitions, the appliance's functions can be simulated in demo mode without having to put the appliance into operation. This saves time and money as the cooling function is not required.
Implementation for external sensors
To additionally monitor the storage temperature using a separate sensor, cabling is required from the outside to the inside. The cable entry offers a clean and professional solution here. The integrated opening enables connection without drilling holes or interrupting the door seal.
Hidden customer menu
Protected, secure, simple: the hidden customer menu provides users with status information about the appliance or allows them to make detailed appliance settings, such as resetting to factory settings. As this information and settings are on a separate, code-protected menu level, unwanted changes or manipulation are prevented.
Hidden technician menu
The hidden service menu enables individual configuration of the appliance, such as alarm sound on/off, customised setpoint ranges or changes to the automatic defrost function. With the help of technical fine adjustments, the appliance can be customised to your specific needs.
Integrated data logger
To ensure complete traceability independently of monitoring systems, the integrated data logger records the temperature profile, alarm history and service information for up to five years. The stored data can be read out directly on the device via a USB interface.
Intuitive menu navigation
Self-explanatory, convenient and clear: the control panel seamlessly integrated into the door shows detailed appliance information and your current appliance status on a large display, which is colour-coded differently depending on the topic. The menu navigation is self-explanatory and is controlled by ''Touch and Slide''.
LED front lighting
Even in dark surroundings, the LED front lighting ensures optimum illumination of the drawers. Thanks to the perfect overview, the desired substance is immediately to hand, the door is quickly closed again and the internal temperature is stable. For low consumption and lower energy costs.
Virtually maintenance-free
Saves time, nerves and costs: Professional Liebherr free-standing appliances work without filters or other components and parts that require regular replacement. Only regular cleaning and calibration according to your individual requirements are necessary.
Standard IEC 61010-2-011 Standard
Liebherr refrigerators and freezers specially developed for the storage of temperature-sensitive products are CE safety-compliant. This means that all mechanical and electrical requirements for injury-free operation are guaranteed - and you and your staff are always on the safe side.
Power failure alarm
An integrated rechargeable battery provides a visual and audible alarm in the event of a power failure and takes over the power supply to the display. As soon as power is restored, the time of failure and the maximum temperature reached are displayed.
PT1000 product sensor
In addition to the integrated control sensor, a further, separate sensor can be connected to measure a simulated product temperature. The product sensor temperature shown on the display can be calibrated independently; device alarms and min/max limits are based on this value. For greater storage safety based on real product values.
Quick guide
Nobody likes reading instructions. That's why Liebherr provides an overview of the most important information on two pages. This includes information on menu navigation, the electronic lock, cleaning and general topics such as permitted/not permitted stored goods. You can leave the reading of the original manual to the technician.
Cleaning / disinfectant recommendation
Liebherr appliances are designed for a service life of 15 years. To maintain this, cleaning agents and disinfectants that have been tested by Liebherr for safe use are recommended in the manual or separately. This way you can be sure that you are not harming your appliance while you are actually doing it good.
Reminder function
The reminder function reminds you when the next basic cleaning or calibration is due. The interval can be selected at predefined intervals and set directly on the appliance. And your mind remains free for your valuable work.
Self-closing door < 90° / automatic door closing at 90°
Convenience for routine work, safety in the event of carelessness: from an opening angle of approx. 90°, the appliance door remains open and makes loading, unloading and cleaning easier. Below approx. 90° it closes automatically so that the appliance is not accidentally left open. This keeps the temperature stable and preserves the quality of your stored substances.
Settings with password protection
All settings that affect the function or control of the appliance can be password-protected. This means that the contents are optimally protected against unwanted changes or manipulation of the storage conditions.
Side-by-side set
The accessory kit offers a neat and secure solution for placing several appliances in a row. The appliances are firmly connected to each other via a profile rail so that they cannot slip and form a seamless front. The fixation also guarantees the recommended spacing and prevents condensation between the appliances.
Sturdy castors
With retrofittable castors as accessories, professional appliances for storing temperature-sensitive products remain as mobile as possible. This means you can change the installation location at any time or simply move the appliance for easier cleaning.
Min/max temperature recording
Always keep an eye on the temperature: The min/max temperature recording saves the minimum and maximum values of the interior temperature from a defined start time and shows them clearly on the display. This means you can be sure that the storage temperatures were within the tolerated limits up to the time of reading.
Air circulation cooling
Highly efficient fans ensure rapid cooling of freshly stored goods and a uniform cooling temperature throughout the interior.
Temperature alarm
The integrated temperature alarm signals if the temperature exceeds or falls below the alarm limits. This alarm is equipped with both acoustic and visual signalling, thus ensuring maximum safety for the stored goods.
Temperature stability and consistency: EN 60068-3
All laboratory refrigerators and freezers are tested in Liebherr's modern development facilities in accordance with the EN 60068-3 test procedure for measuring temperature stability. The temperature is measured at nine different points inside the appliances.
