Final answer:
Recycling or recovery equipment using hermetic compressors has the potential to overheat when drawing the vacuums due to the compression and expansion of gases within the system.
Step-by-step explanation:
Recycling or recovery equipment using hermetic compressors has the potential to overheat when drawing the vacuums because of the compression and expansion of gases within the system. When the hermetic compressor is running, it compresses the refrigerant gas and raises its temperature. The process of compression and expansion generates heat, leading to potential overheating if not properly managed.
