EX-protected refrigerators

Information from the Elektronic-Workshop

We are repeatedly asked to convert household refrigerators to explosion protection ones. Unfortunately, with most devices, this can only be done with a significant intervention in the electronics, which voids the manufacturer's guarantee. The following interior facilities present great difficulties:

  • Lightbulbs
  • Temperature controls
  • Open temperature sensors
  • Drains

Therefore it is necessary to pay attention that none of these installations are situated in a refrigerator which is interesting to be bought.


The portfolio of the company Liebherr includes a large selection of special EX protection devices. These are only available as individual freezers or refrigerators and are slightly more expensive than devices in the consumer sector. Their great advantage is that they are equipped precisely for the intended use in our institutes.
