What component is typically characterized by being bolted together for repairs?

The semi-hermetic compressor is designed for easier access to internal components while still maintaining a closed design to prevent refrigerant leaks. It typically consists of two main sections that are bolted together, allowing for repairs or component replacements without needing to disassemble the entire unit or have to replace it entirely. This feature makes it advantageous for service technicians looking to maintain, repair, or upgrade the compressor without incurring the cost of a completely new unit.

In contrast, the hermetic compressor is fully sealed, which means that once there is a failure, it usually requires replacement instead of repair since it cannot be opened safely for internal diagnosis or repair without losing refrigerant. The reciprocating compressor, while it may allow for some repairs, is not specifically characterized by bolted sections as prominently as the semi-hermetic design. The scroll compressor, while efficient, typically features welded or fixed construction as well, making extensive repairs challenging.

Thus, the semi-hermetic compressor's design, which facilitates repairs by being bolted together, makes it the suitable choice for this question.
