1. Introduction 1.1 – Description The Stirling Ultracold SU780XLE Ultra-Low Temperature Freezer uses a unique free- piston Stirling engine to provide high efficiency, deep-temperature cooling. 1.2 – Intended Uses The SU780XLE freezer provides ultra-low temperature storage for general (non- flammable) research laboratory materials requiring a stable, computer-controlled, deeply-frozen environment. -
Page 7: Introduction
Deep temperatures are dangerous, use proper precautions when operating ultra- low temperature freezers. This ultra-low temperature freezer is intended for storage of frozen sample product or vials at deep temperatures. Stirling Ultracold, a Division of Global Cooling, Inc. cannot be held responsible for damages or loss of stored product attributed to unintended use. -
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. -
