FAQ

Is the So-Low Explosion Proof Manual Defrost Refrigerator Freezer Combo also suitable for flammable material storage?

Yes, it is.

 

What safety designs make this unit suitable for use in a Class 1, Division II, Group C & D environment?

The unit is spark-proof, meaning that all spark generating electrical components and connections (compressor, thermostat) are isolated and sealed in vapor-proof enclosures such that they will not ignite any flammable / explosive vapors unless they are damaged. This is also why the unit must be hard-wired and the unit does not come with a power cord: standard electrical outlets carry a risk of sparking and, therefore, ignition of vapors.

 

Are there special installation considerations for an explosion-proof refrigerator-freezer?

Yes. The freezer must be hardwired to the building's electric and cannot be connected to an electrical outlet via a plug, as that carries a sparking risk. Furthermore, the room / area around the freezer must also be explosion proof. For instance, any nearby equipment also must be explosion proof, any lighting and / or other fixtures must be explosion-proof, and there cannot be any electrical outlets.

ProTip
