By: Cole-Parmer A Stirling engine operates the low temperature freezer, which requires no compressors, dry ice, or LN2, and expends the same volume of energy as a conventional light bulb. The Humm™ free-piston Stirling engine uses two moving parts that float on helium gas bearings to eliminate contact wear. The linear driver modulates engine power to deliver cooling on demand without on/off cycling. The thermosiphon evaporator freezes contents. A microcharge of environmentally friendly cooling medium creates a uniform ultra-low temperature via a continuous process of evaporation and condensation within the sealed tube. Weighing 42 lbs, the portable freezer is efficient for both benchtop and field uses. A weather-resistant touchpad offers digital temperature display indicating interior temperature and error codes. It includes temperature presets of -20⁰, -40⁰, or -86⁰C and a system lock indicator. Adjust by 1⁰C intervals. Features visual and audible alarms. The freezer’s rugged cabinet withstands travel. Its composite vacuum-insulation panels with CFC-free foam protect contents from high ambient temperatures. When not in use, the cabinet can be stored on side, end, or upside down. A double gasket seals the interior chamber and provides dual protection against moisture and heat gain. Molded- End
