Jiaxipera NX1122Y R600a Compressor 1/4 hp Specs and Replacement
Mbsm.pro, Compressor, Jiaxipera, NX1122Y, 1/4 hp, R600a, 200 W, 0.9 A, 1Ph 220-240V 50Hz, LBP, RSCR, -35°C to -15°C, Freezing
The Jiaxipera NX1122Y is a powerhouse in the world of domestic refrigeration. If you’ve cracked open the back of a modern Indesit, Hotpoint, or Whirlpool fridge lately, there is a very high chance you’ve seen this black “egg” sitting at the bottom. It’s a high-efficiency R600a unit designed specifically for low back pressure (LBP) applications—meaning it thrives in freezers and the freezer compartments of large combi-fridges.
Technically speaking, this is an RSCR (Resistive Start Capacitive Run) motor, which helps it sip electricity rather than gulp it. With a displacement of 11.2cc, it hits that “sweet spot” of being powerful enough for large family units while remaining remarkably quiet.
