So-Low | Flammable Material Storage Refrigerator-Freezer Combo Units | Laboratory & Industrial Chemical Safety
At Alto Med Supply, we offer the So-Low Flammable Material Storage Refrigerator-Freezer Combo Units, designed to provide safe, spark-free storage for volatile chemicals and combustible substances in laboratories, hospitals, and industrial research facilities.
Built to meet strict NFPA 45 and 70 safety standards, these units isolate stored materials from potential ignition sources, helping reduce the risk of internal explosions.
The So-Low FMS series includes a range of sizes, from compact 9 cubic foot combination units to heavy-duty 30 cubic foot upright models, making it easy to find a solution for any laboratory footprint.
Each unit is constructed with high-quality steel or anodized aluminum interiors and high-density urethane foam insulation, ensuring long-lasting durability.
A gravity-flow cooling system maintains precise temperature stability without aggressive air circulation, reducing the risk of cross-contamination or temperature fluctuations when doors are opened.
Safety is enhanced with advanced mechanical engineering.
Compressors are housed in vapor-proof enclosures, and all electrical connections are sealed to prevent vapors from contacting electrical arcs.
The manual defrost system eliminates the “cycle-thaw” effect common in auto-defrost units, preserving the integrity of sensitive reagents.
User-friendly digital temperature displays and adjustable shelving make these units both practical and reliable for everyday use.
With their robust construction, precise temperature control, and specialized safety features, So-Low Flammable Material Storage Refrigerator-Freezer Combo Units offer a compliant, high-performance solution for laboratories and industrial environments handling hazardous materials.
Alto Med Supply makes it easy to purchase trusted, top-quality cold storage solutions from leading brands online.
