ATEX Laboratory Refrigerators
chamber in non-sparking design compliance with ATEX directive
CHL ATEX non-sparking (Ex) laboratory refrigerators are specialised units that provide safe storage of chemical samples and other substances that potentially create an explosive atmosphere. Designed for laboratories where the highest safety standards are required, these refrigerators are the ideal solution for Zone 2 according to ATEX Directive 2014/34/EU.
The CHL ATEX spark-free laboratory refrigerators feature an explosion-proof design (for the chamber), as confirmed by the specific ATEX designation. They are designed for use in potentially explosive atmospheres other than underground mines (Group II). The interior of each cooling compartment meets the requirements of Category 3G, ensuring safety in the gaseous explosive atmosphere of Zone 2.
The refrigerators chambers are made in an explosion-proof manner , complying with the ATEX Directive 2014/34/EU (on equipment) and the relevant standards. This is crucial to ensure safety in designated explosion risk zones, which the employer determines on the basis of the ATEX Directive 1999/92/EC.
LABORATORY REFRIGERATORS IN NON-SPARKING DESIGN
Spark‑free CHL ATEX (Ex) Laboratory Refrigerators: Safe Storage of Samples in Explosion‑Hazard Zones
The unit features an explosion‑proof chamber (Ex) II -/3G h IIC T6 -/Gc in accordance with the ATEX designation
Key Safety Features (per the ATEX label):
- Ex: confirms that the interior of the unit is explosion‑proof, compliant with ATEX 2014/34/EU and relevant standards
- II: chamber designed for use in all explosive atmospheres except underground mines
- -/3G: interior of the refrigerator chamber meets Category 3G requirements, meaning it is safe for a gaseous explosive atmosphere in Zone 2
- h: indicates that, as a non‑electrical device, the interior of the chamber is protected by constructional safety “c” per EN ISO 80079‑36
- IIC: denotes that the chamber can be used in the presence of highly explosive gases such as hydrogen or acetylene
- T6: specifies the temperature class, meaning the chamber’s internal temperature remains safe for substances with an auto‑ignition temperature of at least 85 °C
- -/Gc: provides the equipment protection level (EPL Gc), ensuring safe operation of the chamber’s interior in a gaseous explosive atmosphere of Zone 2
Operating Range and Precision:
The spark‑free CHL ATEX laboratory refrigerators feature a forced‑air cooling system, ensuring stable and uniform conditions throughout the chamber. They allow sample storage from 0 °C to +15 °C. Control is managed via a precise SMART controller, guaranteeing high stability and uniformity of the set temperature.
The CHL ATEX (Ex) spark‑free laboratory refrigerator is a reliable and safe solution for storing sensitive samples in environments at risk of explosive atmospheres.
