Bard 8000-451BX - Scroll Compressor

Bard part number 8000-451BX is an OEM Copeland scroll compressor, model ZPS51K6E-TFD-130, supplied boxed for service replacement in Bard wall-mounted HVAC equipment. This compressor is the heart of the refrigerant circuit, restoring proper compression and refrigerant flow when a system has a failed, locked, noisy, or inefficient compressor. As a factory-correct Bard replacement, it is intended to match the original electrical and mechanical requirements for the unit application, helping bring cooling performance and reliability back to spec. Confirm refrigerant type, voltage, and unit model compatibility before ordering, and follow best practices during change-out such as evacuation, drier replacement, and proper start-up checks to protect the new compressor.

What does the "BX" suffix mean?

Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.

A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.

Example: 8406-142BX is physically identical to 8406-142.
