Reciprocating Compressor CR42

Reciprocating Compressor CR42

Reciprocating Compressor CR42 This is a hermetic refrigeration compressor designed for use with R22 refrigerant. It operates on a single-phase power supply with a voltage range of 198-264V AC. The compressor features a capacitor start and capacitor run (CSCR) electrical circuit, ensuring efficient performance. It includes an internal overload protector for safety, preventing damage due to overheating or electrical faults. The unit requires a relay (LT85004) for proper functionality. The compressor’s run capacitor is rated at 40 or 45 microfarads at 275V AC, while the start capacitor has a higher rating of 130/156 microfarads at 275V AC. This model is commonly used in air conditioning and refrigeration applications. It is built to withstand high-pressure refrigerant cycles, ensuring reliable cooling performance. The black metal casing provides durability and protects internal components from external damage. With a solid mounting base, the compressor can be securely installed in various systems. It has designated suction and discharge ports for efficient refrigerant flow. A warning label on the unit advises users to follow safety precautions strictly. Handling should be done only by qualified professionals to avoid injury or damage. Before servicing, it is essential to disconnect the power supply. Proper wiring, as per the application diagram, is crucial for safe and efficient operation. The unit should not be operated outside its recommended voltage range to prevent electrical failure. Regular maintenance, including checking the capacitors and electrical connections, is necessary for long-term performance. This compressor is designed for optimal efficiency, making it a reliable choice for cooling applications.
