Page 8: Features Of The Su780Xle
The SU780XLE Ultra-Low Temperature Freezer uses the Stirling Ultracold Model M600 free-piston Stirling engine to provide high efficiency, deep-temperature cooling. No HCFC or CFC refrigerants are used in the M600 and SU780XLE. The M600 Stirling engine uses approximately 10 grams of helium gas as a working fluid. Approximately 90 grams of R-170 (Ethane) is used in the thermosiphon which removes heat from the freezer. -
