Liebherr’s energy-efficient refrigerators and freezers

ActiveGreen

For Liebherr, ActiveGreen starts early on in the design stages of

professional refrigerators and freezers. Liebherr uses high-quality

components for reliable operation and top energy efficiency even if

appliances are exposed to the toughest demands posed by

professional use. By combining precision controllers with highly

efficient refrigeration components, Liebherr’s professional appliances

offer exceptional energy savings. Liebherr is the first company to

change over its entire range of professional refrigerators and freezers

Know-how that matters!

With almost 60 years’ experience, Liebherr-Hausgeräte specialises

in the development and production of the very finest refrigeration

appliances, which offer the highest quality and superb design.

Innovative ideas pushing the envelope when it comes to convenience

and energy saving are regularly incorporated into Liebherr’s

appliances. Back in 1993 Liebherr was the first manufacturer to

change over to CFC-/HFC-free refrigerants for its entire range of

free-standing domestic appliances.

Liebherr’s manufacturing processes are also geared to the

efficient use of resources. Take, for example, the heat naturally

generated during appliance manufacture: it is recycled as heat

energy. Liebherr uses environmentally compatible powder coatings

for all its sheet metal. They contain no solvents and no waste water

which might have a negative impact on the environment results.

The plastic parts are marked for optimal recycling.

to the environmentally friendly R 290 and R 600a refrigerants. They

are HFC-free and have no detrimental effects whatsoever on the

ozone layer and the associated greenhouse effect. In addition to this,

the use of new, highly efficient compressors allows a significant

reduction in the energy consumption of the appliances. All Liebherr

production sites are certified to the international quality standard

ISO 9001 and the international environmental management standard

ISO 14001.

for commercial use

Premium product quality

Product quality and the resulting long useful life are primary

considerations when assessing the environmental life cycle of a

commercial appliance. Liebherr uses high-quality and well-balanced

components thus ensuring a long useful life expectancy. The

refrigeration quality of the appliances plays an important role in

keeping products fresher for longer – an aspect of particular

importance in the professional sector. Rapid cooling, temperature

stability, correct humidity and quick defrosting are key aspects.

Hygiene is another major factor and is fundamental to the design

of all Liebherr professional appliances. For instance, wherever

technically possible, the cabinets are designed and constructed to

avoid joints and seams. As a prime example, the extensive use of

moulded inner liners makes cleaning simpler and more hygienically

effective.

Award-winning energy efficiency

Energy efficiency always has been, and remains, of central

importance to Liebherr. It is one of the major influences on the

design of the commercial appliances. To illustrate the point, Liebherr

received three of the five 2006 ProCool awards for energy-efficient

and environmentally friendly refrigerators and freezers for commercial

use. The energy consumption of the award-winning appliances was

as much as 70 % below the market average. Liebherr’s extremely

Environmentally friendly in two respects

Liebherr is the first manufacturer to have changed over to

environmentally friendly HFC-free refrigerants for its entire range of

professional refrigerators and freezers for commercial use. Exclusive

use is made of the ecologically harmless R 290 and R 600a

refrigerants. Due to the changeover to these environmentally friendly

refrigerants, refrigeration components of even greater efficiency can

be employed, making the entire range even lower in energy

consumption.

energy-efficient commercial appliances also enjoy top energy

consumption rankings in various international countries and states,

such as the Netherlands or California. Precision electronic control

systems, optimised refrigeration components, maximum insulation,

and highly efficient compressors ensure that energy efficiency is

constantly improved.

Innovative expertise and drive in the laboratory sector

T

he demands made on refrigerators and freezers are particularly

high in all the sectors of professional use. Whether the issue is the refrigeration performance, specifying the materials, designing the refrigeration components or evolving the design concepts – all the decisions are directed to ensuring the long-term, trouble-free use of our appliances.

The most stringent reliability and safety standards apply to appliances in the laboratory sector. Therefore Liebherr has a range of purposebuilt and factory-designed laboratory appliances in different temperature ranges for numerous applications. The MediLine appliances incorporating Proﬁ electronic controllers offer many advantages. High-grade materials, high-performance components and accurate workmanship right down to the last detail ensure the high quality of the Liebherr appliances.

The Proﬁ electronic controller

The menu-guided Proﬁ electronic controller with integrated real-time clock allows the temperature to be set to 1/10°C accuracy. The text display has German, English, French, Spanish or Italian language setting options. To satisfy laboratory hygiene requirements, the electronic controller is ﬂ ush-ﬁ tted and has an easy-clean membrane keypad.

Mains-independent power supply of the electronic controller

In case of power failure, the electronic controller continues to operate from an integrated 12 V battery. As a result, the memory continues to log the internal temperatures for another 72 hours even in the event of power failure. Furthermore, if external alarm and documentation systems are connected, the data transfer is maintained for as long as 72 hours.

Integrated alarm systems

A visual and audible temperature alarm alerts the user if temperature deviation limits are exceeded. In addition, a visual and audible alarm is activated if the door is open for longer than 1 minute. There is also an immediate visual and audible alarm in the event of power failure.

Integrated data memory

The Proﬁ electronic controller has an integrated data memory which logs the last 30 alarm events including date, time and maximum temperature as well as the internal temperature proﬁ le at 4-minute intervals. 2800 temperature logs are stored to memory, which corresponds to approximately a 7-day logging period.

3-point calibration

The laboratory appliances with Proﬁ electronic controllers provide 3-point calibration for extremely accurate temperature control. This permits compensation between the set temperature and the actual internal temperature at as many as three temperature points. Positive or negative changes to the correction value can be made in steps of 0.1K.

Laboratory refrigerators and freezers with Proﬁ electronic controller

Energy-efﬁ cient hot-gas defrost system

The hot-gas defrost system with demand and time control permits very short defrost cycles: only 8 minutes for laboratory refrigerators and 12 minutes for laboratory freezers. As a result, the internal temperature remains almost constant during the defrost cycle. In addition, there is the option of initiating the defrost manually.

External temperature and alarm documentation

The laboratory appliances with Proﬁ electronic controllers are equipped with a volt-free contact for alarm forwarding to an external remote warning system. The data stored in the internal memory can be read out via the infrared interface and transferred to a PC with documentation software. In addition, the appliances have an RS 485 serial interface enabling as many as 20 appliances to be networked with a central documentation and alarm system.

High-quality interior for versatile use

The smooth compartment liners are made entirely of 304-grade stainless steel and are therefore particularly easy to clean. The robust trayslides can be easily repositioned to suit needs and, together with the plastic-coated grid shelves, they ensure versatile use of the interior. The trayslides are U-shaped to make the grid shelves non-tilting.

Maximum temperature stability and temperature consistency

Maximum temperature stability is ensured by the high-performance forced-air cooling system with double ventilation, in conjunction with optimal routing of the air ﬂ ow. The very short defrost cycles allow the internal temperature to be kept almost constant during the defrost phase. All the laboratory appliances are tested according to the NF X 15-140 standard with regard to maximum temperature stability and optimal temperature consistency.

Access port for an external temperature sensor

In the laboratory appliances with Proﬁ electronic controllers there is provision for an independent temperature sensor allowing, for instance, a PT 100 probe or similar measuring elements to be positioned in the interior. The diameter of the access port is 7.6 mm.

Refrigeration components

The refrigeration components are securely integrated in the ceiling area, allowing ready access. The compressor compartment panel can be simply raised for cleaning or servicing purposes and can be fully detached from an opening angle of 45° to provide very good access to the refrigeration components.

Electric defrosting Hot gas defrosting

Castors

The LKPv and LGPv ranges come with castors as standard to allow easy and convenient cleaning underneath and versatile use of the appliances in different rooms. The brake of the two front castors provides a ﬁ rm hold and ensures that the appliances cannot tip even if the grid shelves are extended. The castors can be removed in order to transport the cabinets. Doing so the height of the cabinets will be reduced by 13 cm.

Practical door

The doors remain open at 90° and are self-closing at less than 60° for convenient use. The integrated lock is exceedingly sturdy and protects the stored products against unauthorised access. The door hinges are interchangeable and the door seals are replaceable.

Infrared key with documentation software

The alarm events and temperature proﬁ le data can be read out using the infrared key available as an accessory. Corresponding documentation software is included enabling visualisation of the read-out data on a PC.

Interface converter with documentation software

A special interface converter including documentation software is available for central documentation of the temperature proﬁ le data and alarm events of multiple appliances via the RS 485 serial interface. Capability is provided for interconnecting as many as 20 laboratory appliances and centrally documenting their parameters.

NTC product temperature probe

An NTC product temperature probe for logging product temperatures is available as a retroﬁ t kit for the laboratory appliances with Proﬁ electronic controllers. The logged product temperatures can either be read by the electronic controller or transferred to an external documentation system via the existing RS 485 interface.

Functional and practical accessories

U-shaped trayslides and grid shelves

Additional U-shaped trayslides and plastic-coated grid shelves can be retroﬁ tted as required to provide extra storage options. The robust grid shelves have an extremely high loading capacity of up to 60 kg.

he low temperature -45 °C chest freezers are designed to meet

the speciﬁ c requirements of an array of research, industrial or clinical applications. Where there is a need to store products or samples at lower than usual freezing temperatures freezers are the ideal solution. Offering supreme temperature stability as well as temperature uniformity within the units, they ensure the safe, cold storage of specimens, biological samples and other substances.

The low temperature chest freezers are available in three sizes and are equipped with a precision digital controller, which guarantees maximum temperature accuracy. Having a volt-free contact and an RS 485 serial interface, Liebherr’s low temperature chest freezers can also be connected to a central alarm and documentation system, which provides additional safety for the samples within the unit.

The Comfort electronic controller

The precision Comfort electronic controller with digital temperature display enables temperatures to be set accurately. Symbols indicate the operating status of the appliance at all times. To satisfy laboratory hygiene requirements, the Comfort electronic controller has an easy-clean membrane keypad.

External temperature and alarm connections

The low temperature chest freezers with Comfort electronic controllers are equipped with a volt-free contact for alarm forwarding to an external remote warning system. In addition, the appliances have an RS 485 serial interface for central documentation of the temperature proﬁ le data and alarm events.

Integrated alarm systems

A visual and audible temperature alarm alerts the user if temperature deviation limits are exceeded. The parameters for the temperature alarm can be individually set. In addition, a visual and audible alarm is activated when the lid is open for longer than 1 minute. The door-open alarm delay can be adjusted between 1 and 5 minutes. Furthermore, the laboratory appliances with Comfort electronic controllers have a visual power failure alarm when mains power returns and a sensor defect alarm.

Integrated data memory with min/max temperatures

The Comfort electronic controller has an integrated data memory. It logs the maximum and minimum internal temperatures that occurred once the set temperature was reached, the last three temperature alarms and power failures, together with the time, date and duration of the alarm. The respective data can be recalled using the AlarmLog function and read on the display panel.

1-point calibration

The low temperature chest freezers with Comfort electronic controllers provide 1-point calibration for accurate temperature control. This permits compensation between the set temperature and the actual internal temperature. Positive or negative changes to the correction value can be made in steps of 0.1K.

StopFrost-System

The Stop-Frost system ﬁ tted to the LGT models has 2 major advantages: frosting of the freezer and its contents is signiﬁ cantly reduced. This means the time-consuming process of defrosting is necessary far less often. The vacuum is also equalised quickly after the lid has been opened and closed and the chest freezer can be re-opened effortlessly.

Lid handle

The aluminium lid handle of the LGT models is simple and tough for intensive commercial use. All models have locks as standard.
