Product Number: 7597N
The WAI 7597N is a brand-new 12V 23A alternator. It is built to the Motorola IR/EF specification, replacing original-equipment units referenced under Remy 93081, Prestolite 110-581, and Thermo King 412194 among 13 cross-references in total. It is engineered for Thermo King refrigeration units, covering 24 applications across the HK, KD-II, MD-200, MD-300, and MD-II model lines.
The IR/EF (internal regulator, external fan) design integrates the voltage regulator inside the housing, reducing external wiring complexity and making installation straightforward on machines where space around the unit is limited. Bi-directional rotation means the same unit serves both clockwise and anticlockwise drive arrangements, so there is no need to specify rotation at the point of order. A groove pulley is fitted as standard.
At 23 amps output, this alternator is rated to meet the charging demands of the Thermo King systems it serves, keeping batteries topped up reliably during transport refrigeration operation.
