Liebherr explosion-proof (ATEX) laboratory freezers

Liebherr explosion-proof (ATEX) laboratory freezers

 

Liebherr explosion-proof (ATEX) laboratory freezers can safely store flammable solvents, hazardous chemicals and temperature-sensitive samples in a frozen state.

The freezers provide stable, uniform temperature control, which is essential for preserving the quality of samples and reagents over the long term.

They are ideal for chemical, pharmaceutical and research laboratories where enhanced safety and regulatory requirements are essential.

Liebherr ATEX laboratory freezers offer a reliable, long-term solution for safe and controlled laboratory freezing.

Explosion-proof design – ATEX-certified

The interior chamber of the appliances is explosion-proof (Ex), with the following ATEX marking:

II 3/- G Ex h IIC T6 Gc/-

• The chamber interior is suitable for Zone 2 explosive gas atmospheres

• The freezer contains no spark-generating components

• The interior is safe even in the presence of gases such as hydrogen or acetylene

One of the key advantages that sets Liebherr appliances apart on the market is the comprehensive 5-year warranty. This means more than an extended warranty; it also provides genuine assurance: 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, allowing connection to a building management system (BMS) or an external alarm system. In the event of an alarm, the relevant control centre is notified immediately, enabling rapid intervention in critical situations.
