Stringent demands in the laboratory sector

Liebherr laboratory appliances store highly sensitive and explosive substances safely and reliably. Innovative refrigeration technologies and a host of smart functions guarantee optimum storage conditions, with excellent temperature consistency. Our appliances are designed to keep costs down, and to keep the amount of work involved in their operation and maintenance as low as possible - without compromising maximum safety.

Storage of sensitive substances

Clinics and laboratories conduct research on highly sensitive substances, such as serums and antibodies. As a result, sensitive substances, liquids and cultures require storage. Precise measuring methods and reliable output data are crucial to the quality and usefulness of the research experiments, process controls and tests. Obviously, in this work, exceptionally high requirements exist with regard to temperature reliability, safety, hygiene, and the storage conditions that appliances offer.

Maximum temperature reliability

Constant temperatures are crucial for the safe storage of sensitive and explosive substances - even minor deviations can impair their storage life and usefulness. In Liebherr laboratory appliances, innovative refrigeration technologies and precise control systems ensure constant interior temperatures, and keep energy consumption comparatively low. Numerous alarm functions offer safeguards in the event of a fault.

Our laboratory appliances comply with the relevant industry standards and statutory safety regulations.

Security assurance during everyday work

Liebherr laboratory appliances are characterised by optimum temperature reliability thanks to innovative technologies and control systems. However, optimum storage conditions alone are not enough to guarantee safe storage. People use these appliances during everyday lab work, so they have to function within the framework of normal working processes and routines. Operating errors and unforeseeable circumstances naturally occasionally arise, and therefore, Liebherr considers preventative and reactive measures when developing these appliances.

Liebherr laboratory appliances offer innovative refrigeration technologies and benefit from useful security features and safeguards that give assurance in everyday working life.

Why Liebherr laboratory appliances are safe

Our laboratory appliances are designed in accordance with standard EN 60068-3 to offer maximum temperature stability and temperature consistency. Constant interior temperatures are maintained by the forced-air cooling system and by optimum airflow within the interior.

During everyday laboratory life, frequently opening appliance doors, or leaving them open for too long, will lead to temperature fluctuations that have to be compensated for – or ideally, avoided in the first place. Liebherr appliances come with self-closing doors and, in the event of significant temperature deviation, the appliance immediately triggers acoustic and visual alarms.

In research and laboratory environments, the highest hygiene standards have to be met, and this means that the appliances have to be regularly cleaned, and therefore be resistant to the stresses associated with abrasion and chemical agents. Easy-to-remove shelves and smooth, seam-free interior surfaces make Liebherr appliances easy-to-clean. Recessed seals prevent the accumulation of dirt and dust. The floor beneath appliances can be easily accessed and thoroughly cleaned thanks to smooth-running castors on the appliances' undersides.

Made from only premium-quality, tried-and-tested materials, our laboratory appliances are particularly strong and durable, and feature a scratch, impact and corrosion-resistant coating. The plastic-coated grid shelves aptly fulfil hygiene requirements and are particularly robust. We manufacture our mechanical parts such as door handles, hinges and locks to function efficiently and without problem for many years, even when frequently used.

Robust locks, installed as standard, prevent unauthorised access. Furthermore, to only provide access to certain people, some appliances can be fitted with optionally available additional lock barrels.

Liebherr offers special refrigerators and freezers for storing flammable materials. The spark-free interior meets the requirements for Class I, Division 2.

Even the highest quality, strictest safety procedures are unable to completely prevent defects occurring. Our refrigerators with Comfort electronic controls therefore come with an additional safety thermostat, which assumes control in the event of a fault and prevents the temperature from falling below +2°C.

In addition to reliable and safe operation, Liebherr also develops its appliances so that they will work efficiently, with minimal maintenance necessary, for many years.

Procurement and operating costs

The research and laboratory sectors are subject to major cost pressures. When procuring appliances that have to work continuously, ongoing operating costs and additional expenses play a critical role in making purchase decisions. Consideration is given to factors such as reliability, expected repair and servicing costs, and the anticipated service life of the appliances.

Quick and easy maintenance

Depending on the application, legislators often require that appliances in the laboratory sector be regularly maintained for liability reasons. It must be possible to conduct the necessary servicing processes and actions quickly and efficiently.

In Liebherr appliances, all components and displays used for calibration and monitoring are easy-to-access and operate.

Minimal downtime and few repairs

Liebherr appliances are particularly durable and work reliably with almost no wear. To minimise downtime, we only use premium-quality, long-life components. For instance, our compressors and condensers are designed to work highly efficiently for many years, and our fans and relays are also virtually wear-free. Furthermore, we offer a ten-year spare parts guarantee.

Low energy consumption

Our laboratory appliances are particularly energy efficient. During everyday use, optimised insulation and environmentally friendly R 290 and R 600a refrigerants contribute significantly to appliance economy. The hot-gas defrosting system increases efficiency, as the defrosting cycles are much shorter than conventional electrical defrosting systems. Demand-responsive hot-gas defrosting helps to reduce electricity costs, and ensures that temperatures in the interior are virtually uninterrupted.

Optimum networking

Liebherr laboratory appliances can be easily integrated into existing infrastructures. Networked with other appliances and connected to external systems, they help to efficiently monitor processes like calibration, data management and documentation.

Automatic documentation and alarm functions

Documentation is an unavoidable and time-consuming part of everyday laboratory life. And, for many applications, data recording is required for more than just legal reasons: continuous recording and monitoring are crucial to the validity of tests and, in the case of incidents, these records document the course of events and responsibilities.

Liebherr appliances with Profi electronic controls have integrated data storage for automatic documentation purposes. All models can be integrated into the existing on-site infrastructure, individually or via serial interfaces.

Functions and accessories for documentation

  • 24/7 monitoring
    Appliances with a Profi electronics can be connected to an external alarm system by means of a potential-free contact. This ensures that the refrigeration process is continually monitored and documented, whether or not staff are present.

  • Integration into existing systems
    The central data management system reduces the documentation-related workload. The RS 485 serial interface can be used to network up to 20 appliances. An optionally available interface converter connects the networked appliances to a computer, and the documentation software notifies the relevant personnel about any alarms by e-mail and provides all the data required.

  • Continuous documentation
    In the event of uncertainty, the continuous documentation can reveal where the blame lies if temperature fluctuations and incidents activate alarms. The integrated data memory records over 2,000 temperature readings at regular intervals to enable differentiated analysis.
