Several models are available that offer the user a variety of wattage options. The coolers utilize the Stirling thermodynamic cycle for their high efficiency.
Long life is sustained by the use of dry lubricated clearance seal and linear-drive technology.
This feature is available in the electronics module which provides the drive and control functions. The Model 500, at bottom right, provides 500 mW of refrigeration. At top right, the Model 600 meets the US Army s 0.35 Watt linear requirements. Lower left is the Model 1000 which is designed to meet the US Army s One-Watt cooler requirements. At top left is the Model 1750 which is designed to meet the US Army s 1.75 Watt linear cooler requirements.
