Tecumseh AJ 2464 P-TZ (Old Code: TAJ 2464 Z) 1.5 Hp R-404A Refrigeration Compressor

The TAJ 2464 Z compressor by Tecumseh (France), well known in commercial refrigeration, is now produced under the code AJ 2464 P-TZ following the brand's global catalogue update. The code change is only a naming standard: housing dimensions, connection layout and cooling capacity are identical. You can fit this original compressor with its new code in place of a failed TAJ 2464 Z as a direct drop-in, without modifying the chassis or the fittings.
