So-Low | Flammable Material Storage Refrigerators (5 to 30 cu. ft.)

So-Low | Flammable Material Refrigerators | UL/ETL Listed 1–10°C Lab Storage with CFC-Free Cooling and Adjustable Shelving

Alto Med Supply offers So-Low Flammable Material Refrigerators, designed for safe and reliable laboratory storage between 1°C and 10°C.

Available in sizes ranging from 5 to 30 cubic feet, these refrigerators use CFC-free refrigerants and insulation and are UL or ETL listed for safety compliance.

Engineered for laboratories handling volatile chemicals and flammable materials, So-Low FMS Refrigerators feature a spark-free interior with all electrical components sealed in vapor-proof enclosures, eliminating internal lights, fans, or switches that could trigger ignition.

Each unit is equipped with a high-performance microprocessor temperature controller, maintaining precise temperatures throughout the 1°C to 10°C range.

The refrigerators are constructed with high-density, CFC-free urethane foam insulation for thermal stability and a durable powder-coated steel exterior to withstand demanding laboratory or industrial environments.

For added security and organization, every model—from compact 5 cu. ft. undercounter units to 30 cu. ft. upright models—includes a heavy-duty keyed door lock and adjustable shelving to accommodate different storage needs.

Available in Cycle or Manual defrost configurations, So-Low FMS Refrigerators suit a wide range of laboratory protocols.

Smaller models, such as the MV4-6UCFMSR, are ideal for space-limited undercounter applications, while the larger DHH4 series provides vertical storage for high-volume facilities.

Operating on a standard 115V power supply, these refrigerators combine professional-grade cooling technology with essential safety features required for NFPA and OSHA-compliant laboratory risk management.

Alto Med Supply brings these trusted So-Low units to laboratories nationwide, providing versatile, secure, and reliable cold storage solutions.
