We bring you the Thermo Scientific explosion-proof refrigerator model 3557-1 that is specially designed to be used in areas where ignitable materials are normally present. The spark free interior and tough white exteriors reduce the risk of explosion. It comes with plug-free cords, so the electrical connections are hardwired to prevent sparking and accidental disconnection. The thermostat and compressor components are safely isolated within a vapor-proof enclosure. The single solid door is featured with a built-in key-lock and magnetic vinyl gaskets for positive door seal. The 240 volt, manual defrost refrigerator can be used in Class I, Division I Group C and D hazardous environments.
