Liebherr Perfection/Performance compact undercounter freezers
Compact undercounter laboratory freezers
Liebherr undercounter laboratory freezers are an ideal solution for laboratory environments where both space-saving design and reliable sample storage are essential. Their compact size allows easy integration beneath workstations while ensuring stable, uniform temperatures for sensitive samples.
The Perfection series supports critical applications with more advanced controls and enhanced safety features, while the Performance series provides a reliable, cost-effective solution for everyday laboratory use. Even in this size category, Liebherr quality ensures long-term operational reliability.
Liebherr Perfection series models comply with the requirements of DIN 13277.
One of the key advantages that sets Liebherr appliances apart on the market is the comprehensive 5-year warranty. This provides more than just extended warranty coverage; it offers genuine peace of mind: the manufacturer is confident in the reliable long-term operation of the equipment, enabling users to plan for predictable, stable operation.
The comprehensive 5-year warranty is particularly important for those who:
• operate a laboratory continuously
• cannot afford unexpected downtime or temperature fluctuations
• are looking for a reliable, auditable long-term solution
Liebherr undercounter models are also available in benchtop versions, which are not listed separately on this page.
Potential-free alarm relay
The appliances feature a potential-free alarm relay, enabling connection to a building management system (BMS) or external alarm system. In the event of an alarm, the relevant control centre is notified immediately, enabling a rapid response in critical situations.
