Import Tips
• Provide thermal performance curves demonstrating liquefaction capability to distinguish from simple cryocoolers
• Document as complete functional unit, not heat exchanger part, for proper machinery classification
• Ensure RoHS compliance declarations for electronic components in cryocooler assemblies
