CHL ATEX (Ex) Laboratory Refrigerators: Safe Storage of Samples that May Create an Explosive Atmosphere
CHL ATEX devices feature explosion-proof (Ex) chambers II 3/- G Ex h IIC T6 Gc/- in accordance with ATEX directive markings.

Key Safety Features (according to the ATEX label):
- II: device intended for all explosion-hazardous areas except underground mines (Group II)
- 3/-: category applies only to the interior of the refrigerator chamber, meeting category 3 requirements for zone 2 explosive atmospheres.
“/-” means that the device’s exterior is not intended for operation in explosive hazard zones. - G: type of explosive atmosphere – gas
- Ex: explosion-proof design, in accordance with ATEX Directive (2014/34/EU) and relevant standards
- h: non-electrical device, the interior of the refrigerator chamber is protected by constructional safety “c” in accordance with EN ISO 80079-36
- IIC: gas explosion group, device approved for operation in the presence of highly explosive gases such as hydrogen or acetylene
- T6: device temperature class – the interior of the cooling chamber is safe for substances with an auto-ignition temperature of at least 85 °C
- Gc/-: Protection level of the device chamber (EPL Gc) according to the Ignition Hazard Assessment. Ensures safe operation of the chamber interior in a zone 2 gas explosive atmosphere. The symbol “/-” means that the exterior of the device has no assigned EPL and is not intended for use in Ex zones.
Operating Range and Precision:
CHL ATEX laboratory refrigerators with explosion-proof chambers feature a cooling system with forced air circulation, ensuring stable and uniform conditions inside the chamber. They allow sample storage within a temperature range of 0 °C to +15 °C. The device is controlled by a precise SMART controller, guaranteeing high stability and uniformity of the set temperature.
The CHL ATEX (Ex) laboratory refrigerator with an explosion-proof chamber is a reliable and safe solution for storing samples that may create an explosive atmosphere.
