Spark resistant refrigerator for storing flammable materials

If you work, among other things, with flammable substances or chemicals in your laboratory, a laboratory refrigerator in spark resistant design is necessary. This ensures safe storage and protection of your employees. Otherwise, an open or leaking container poses the risk of an explosion being triggered by a spark. For this reason, there are precise specifications for the storage of hazardous substances and for the refrigerators used for this purpose, the interiors of which must be free of ignition sources. The regulations are partly laid down in Directive 94/9/EC issued by the EU and are described in detail in that paper. In our range, we offer you a selection of low-maintenance spark resistant refrigerators with a cooling capacity of 180 to 2,300 litres. In addition, we manufacture special sizes on request, so take the time to discover the optimal refrigerator or deep freezer in spark resistant design for your laboratory and set the course for a safe workplace.


Individualise your spark-resistant refrigerator with accessories

Our smallest spark resistant refrigerator has a temperature controller with a capillary sensor on the outside, with which you can set a temperature range from 1 to 15 °C. Our product range also includes variants with the touchscreen temperature controller TC 2015. You can operate the controller via the password-protected display and additionally show event lists or the temperature curve graphically. Stored data can be exported for archiving via the USB port or Ethernet.

All of our laboratory refrigerators (spark resistant as well as standard) have recirculating air cooling, which ensures permanently constant temperatures. You have various options to customise the refrigerator to your requirements, for example by choosing a stainless steel interior or a glass door instead of galvanised, powder-coated sheet steel. For optimal storage of hazardous substances, you can purchase additional stainless steel shelves or drawers. Take a look at our wide range of products to find the ideal spark resistant refrigerator, combined refrigerators and deep freezers or cooling rooms for your laboratory. The technical details for the respective models as well as optional accessories are available on the data sheets on this website.
