Safeguard your laboratory with our 100% flammable material refrigerators/ freezers, designed to prevent explosions both inside and outside—even in a hazardous material location.

Our Thermo Scientific Flammable Material Refrigerators/Freezers meet OSHA, UL, and National Fire Protection Association safety standards. Every motor and thermostat is designed to prevent the arcing that could ignite a flammable vapor-air mixture. Each unit has wiring, splices, a thermostat, relay and compressor motor safely housed in an enclosure suitable for use in Class 1, Group C and D hazardous environments. And the surface temperature of the compressor will remain below the flashpoint of any flammable material likely to be found in such environments.

All models feature heavy-gauge, rigid, braced-steel construction with a durable enamel finish. Interiors have porcelain enamel, epoxy enamel, or ABS plastic construction. Each unit is insulated throughout for energy efficiency.

Choose from our complete line of refrigerators, freezers, and combination refrigerator/freezers suitable for storing or using chemicals such as cyclopropane, ethyl ether, ethylene, acetone, alcohol, benzene, butane, gasoline, hexane, lacquer solvent vapors, naphtha, natural gas or propane and many other potentially hazardous materials. Select from various models, including single-door and two-door upright refrigerators and freezers, and undercounter refrigerators.

UL LOGOAll units carry a 12-month warranty on parts and 90-day warranty on labor. All Flammable Material models must be hardwired directly to your power source by rigid metal conduit or mineral-insulated cable with fittings which meet Class 1, Group C and D requirements.
