4 Tecumseh AEX compressor maps from the maker's published data — 4 model codes on R290 (4). Every model is a page of its own with its AHRI 540 / EN 12900 map sampled across the published envelope, and every one is selectable in the builder, which solves it with the catalog's own figures.

The rating is the map read at the AHRI 540 air-conditioning point; a dash means the point lies outside the machine's own envelope (a refrigeration compressor is not rated there). The evaporating range is the published envelope's.
Open the builder and pick any of them from the catalog picker, or read one at your own conditions in the compressor-map lookup.
