SCROLL TECH ST-R144 KE-TF5-3PH-220V-60Hz-R407
Scroll Compressor (~12 HP class / ~144,000 BTU/h)
I checked the closest technical match in the same capacity range: the 144K scroll compressor platform (ZR144 class), which is the standard reference used in HVAC systems for this size.
So your ScrollTech ST-R144 KE-TF5 is typically a 12 HP / 144,000 BTU class scroll compressor for medium commercial air-conditioning systems using R407C refrigerant.
