Bitzer Compressor Serial Number Check 【2024】

The first two digits, HG , were not letters but a cipher. H = 8, G = 7. But in Bitzer’s internal system, they used a shifting offset. She cross-referenced a faded table in the manual: H = 2008, G = 2009? No—that was too new. The compressor was older. She reversed the logic: If the unit was installed in 2012, the manufacturing year had to be 2010. She scanned down the table. H = second half of 2010. G = first half of 2011. HG meant the compressor was assembled across the 2010/2011 winter transition. A hybrid batch.

The model number (e.g., 4NCS-12.2Y ) describes design configuration; the serial number identifies that exact physical unit. bitzer compressor serial number check
