Why Choose a Flammable Material Storage Refrigerator?

A flammable material storage refrigerator differs from a conventional laboratory refrigerator because electrical components inside the storage chamber have been eliminated or isolated to prevent ignition of flammable vapors. This allows laboratories to safely refrigerate volatile chemicals in sealed containers while complying with laboratory safety requirements.

It is important to distinguish a flammable material storage refrigerator from an explosion-proof refrigerator. Flammable material storage refrigerators are intended for general laboratory work areas (unclassified locations) where flammable materials are stored inside the cabinet. Explosion-proof refrigerators are designed for installation in classified hazardous environments where flammable vapors may also be present outside the cabinet.
