In a hermetic compressor, the motor is enclosed in a gas-tight housing along with the compressor.

• A. False
• B. Sometimes
• C. True
• D. Not applicable

Answer: (C)

In a hermetic compressor, the motor and the compressor sit together inside one gas-tight housing. This sealed can keeps refrigerant contained, protects the moving parts from moisture and contaminants, and eliminates external shaft seals. Because the motor shares the same sealed environment as the compressor, this arrangement is the defining feature of a hermetic design. That’s why the statement is true: the motor is enclosed in a gas-tight housing along with the compressor.

If the motor or compressor fails, the sealed unit is typically replaced since servicing the inside of the hermetic can isn’t practical. This contrasts with open-drive or semi-hermetic designs, where the motor or parts are accessible or separate from the compressor.
