Laboratory Freezer with Explosion-proof Interior And Re-circulating Air Cooling

Tested and certified independently by TÜV-SÜD: LABEX®-Laboratory Freezers with re-circulating air cooling are intrinsically safe according to the ATEX 95 directive. Each component in the interior compartmend (ventilators, sensors) is particularly shielded to avoid sparks even when malfunction occur.  Your advantage: Maximum explosion proofness and maxiumum temperature consistency.


Intrinsic Safety - Our Unique Selling Postion.

All models with LABEX®-Intrinsic Safety are specifically designed for the storage of explosive materials at optimal temperature consistency. The models are independently tested and certified by the TÜV SÜD Managment Service GmbH regarding:

  • Intrinsically safe supply of the interior: The ATEX 95 directive demands that components (ventilators, sensors etc.) do not generate sparks even when malfunctions occur. Therefor, our LABEX© freezers feature specific saftey barriers that inhibit sparking even for gases with low ignition temperatures. They comply with the highest demanding Temperature class "T6" (surface temperature 85°C).
  • Special conduction concept for electric currents that may arise due to static charge (e.g., operator, use of drawers etc.).



We cover you in two ways: A maximum of explosion proofness and a maxiumum of temperature consistency thanks to our LABEX® technology and the adapted KIRSCH-re-circulating air cooling (optimized air guide panels). The unique combinatin of explosion proofness, automatic fast defrosting, controlled decompression and re-circulating air cooling lead to the safest and best storage conditions for your goods.

Certified  complience with the EU directive 94/9/EC (ATEX 95)

  • intrinsically safe supply of all electronic components (depends on the model)
