Copeland 998-1583-03 Capillary Kit

When you are dealing with high-temp discharge or the integration of a refrigerant injection system on specialized Copeland scroll units, the Copeland 998-1583-03 Injection Capillary Kit is the industry standard for thermal management. This kit is specifically engineered to meter liquid refrigerant into the compressor's scroll set, effectively stabilizing internal temperatures during low-temperature applications or high compression ratios. As a 30-inch capillary tube assembly, it provides the precise pressure drop required for accurate liquid injection cycles, preventing common failure points such as oil breakdown or scroll overheating. Professional HVACR technicians rely on this OEM replacement part for its reliability in commercial refrigeration and industrial cooling systems. Its robust copper tubing construction ensures a leak-free interface with your liquid line and compressor ports, maintaining long-term system integrity without the risk of flow restriction often found in sub-par aftermarket alternatives.

• Thermal Regulation: Precisely manages discharge gas temperatures to protect scroll compressors from thermal fatigue.
• System Reliability: Meters liquid refrigerant accurately to maintain the optimal operating envelope in demanding refrigeration cycles.
• OEM Compatibility: Designed by Copeland for seamless installation into existing injection ports without field modification.
• Leak Prevention: High-grade HVAC capillary tubing minimizes the risk of vibration-induced fractures in 30-inch runs.

What is the purpose of the 998-1583-03 injection kit?
It is used to inject a small amount of liquid refrigerant into the compressor to cool the scrolls during high-head or low-suction operation, preventing high-limit trips.

Is this kit compatible with all Copeland scroll compressors?
No, it is specifically designed for models with dedicated injection ports. Always verify your compressor's model number and the specific refrigerant type (e.g., R-22, 404A) before installation.

Does this kit include a solenoid valve?
This is the capillary kit only. A standard liquid line solenoid or an injection valve may be required separately depending on your specific system control logic.
