Explosion Proof Switches

Everel A1 & SXL5 Switches Tested To Meet EN60079 Explosive Atmosphere Standard.

Cost effective, explosion proof switches for the Refrigeration industry.

refrigerator - explosion proof switchesWith the planned phase out of HFC gases by the European Union, the need to source alternative refrigerants with lower global warming potential is a challenge for Refrigeration manufacturers.  The use of natural refrigerants such as R-290 (propane) and R600a (isobutene) are popular substitutes.  However, one of the potential concerns for natural refrigerants is their flammability.

ice - explosion proof switchesWith this in mind, electro mechanical components used within refrigerators and vending machines need to withstand the more vigorous testing for potentially hazardous environments.  The A1 series and SXL5 explosion proof switches produced by Everel, Italy have been tested to meet the EN60079 regulatory standard.
