The Sigma QD43H Compressor is a compact R134a compressor designed for low-back-pressure (LBP) refrigeration applications. With a 110W cooling capacity and 1/8+ HP rating, it fits smaller refrigeration systems where a compact compressor is required for light cooling loads.
The compressor operates on 220–240V at 50Hz and uses an RSIR starting system. Its compact capacity makes it suitable for small refrigeration equipment, provided the replacement matches the original system's refrigerant, voltage, application range, and compressor specifications.
