: R290 yields superior heat absorption capacity per kilogram, allowing the compressor to use a much smaller chemical charge while lowering overall cycle energy consumption. Evaporating Applications
Keep the process stubs and connection tubes sealed until installation. The total exposure time of the compressor tubes to open air must not exceed 10 minutes to prevent ambient moisture from contaminating the internal oil. This comprehensive guide serves as an exhaustive reference
Measure between each terminal pin (C, R, and S) and a bare, unpainted metal surface on the compressor shell. Any continuity or low-resistance reading indicates an internal short-to-ground, requiring immediate replacement. Critical Handling and Installation Rules
The is a high-efficiency hermetic reciprocating refrigeration compressor specifically engineered for Low Back Pressure (LBP) applications utilizing eco-friendly R290 (propane) refrigerant . Operating primarily at a rated voltage of 220–240V at 50Hz , this compressor delivers approximately 1/3 HP to 3/8+ HP capacity, making it a staple for commercial and heavy-duty domestic deep freezers with volumes ranging from 300 to 350 liters.
