Liebherr Perfection/Performance freezers with plastic interiors
Laboratory freezers with plastic interiors
Liebherr Perfection and Performance laboratory freezers with plastic interiors provide a reliable solution for storing samples safely at stable temperatures in research, diagnostic and industrial environments. The models combine stable temperature control with an easy-to-clean, chemical-resistant interior design.
The Perfection series supports critical sample storage applications with more advanced controls, enhanced safety features and greater convenience, while the Performance series is ideal for everyday laboratory use thanks to its reliable core functionality.
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
Antimicrobial handle with opening mechanism for hygienic use
Liebherr equips all laboratory refrigerators and freezers with plastic interiors with a handle featuring an antimicrobial coating and opening mechanism. This design actively supports hygienic operation and reduces the risk of microbiological contamination.
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.
Liebherr Perfection series models comply with the requirements of DIN 13277.
