Introducing the Thermo Scientific explosion-proof refrigerator model 3566A that is specially designed to prevent triggering an explosion inside or outside the unit. This 120 volt unit comes with plug-free cords, so the electrical connections are hardwired to prevent sparking and accidental disconnection. The single solid door is featured with a built-in key-lock and magnetic vinyl gaskets for positive door seal. The 21 cu. ft. unit has 4 fixed interior shelves and CFC-free insulation and refrigerant. The spark free painted steel interior and tough white exteriors reduce the risk of explosion. The hydraulic thermostat and compressor components are safely isolated within a vapor-proof enclosure. The manual defrost refrigerator is designed for use in Class I, Division I Group C and D hazardous environments with 13 months parts and labor warranty.
