Huayi B43CB Hermetic Refrigerator Compressor – 1/12 HP, R600a, LBP 69 W

Huayi B43CB is a 1/12 HP hermetic reciprocating compressor manufactured for small household refrigerators and freezers. It operates with R600a (isobutane); with a displacement of 4.3 cm³ it delivers a cooling capacity of 69 W (235 BTU/h) under LBP conditions.

Compact R600a LBP Refrigerator Compressor

The B series is a compact compressor family with a height of 145 mm and a weight of 4.6 kg. The product comes with the Huayi label; it is the same model as the Cubigel B43CB, and the capacity values in the technical data sheets of both brands are identical. Its statically cooled body fits capillary tube systems directly.

• 🔥 R600a is a flammable refrigerant (A3 class). Brazing, leak testing and charging must follow the rules for flammable refrigerants: a ventilated area, no sources of ignition and the correct charge quantity are essential. This compressor is for R600a systems only.
• 🔧 When replacing: Match the refrigerant, LBP class and displacement of the old compressor; compare the mounting hole spacing with the dimensional drawing.
• Application limit: This model is LBP — for refrigerators and freezers. It is not used in high evaporating temperature (HBP) applications such as water dispensers and bottle coolers.
