Are the So-Low Explosion Proof Manual Defrost Refrigerators also suitable for flammable material storage?
Yes, they are.
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?
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.
The So-Low Explosion Proof Manual Defrost Refrigerators are identical to the American Biotech Supply Standard Hazardous Location Refrigerators, which are less expensive. They are literally the same units, with the same warranty and certifications. Just get the cheaper one.So-Low 2016-02-13
