Copeland 998-1000-24 Cooling Kit

The Copeland 998-1000-24 is a critical Demand Cooling Kit designed for 4D compressors operating on a 240V power supply. As a technician, you know that managing discharge temperatures is vital when running low-temperature R-22 or R-404A/R-507 systems. This kit provides an active method of cooling the compressor by injecting saturated refrigerant into the suction gas. The 998-1000-24 cooling kit utilizes a specialized temperature sensor to monitor discharge gas, triggering the injection valve only when necessary to prevent oil breakdown and compressor overheating. This HVAC compressor cooling solution ensures your 4D series semi-hermetic compressor stays within its safe operating envelope during high-compression ratio cycles, providing necessary thermal protection without sacrificing energy efficiency.

Key Benefits for Contractors:

• Precise Discharge Control: Maintains optimal internal compressor temperature to prevent valve failure and carbonization of oil.
• Verified Compatibility: Explicitly engineered for Copeland 4D model compressors using demand-based injection logic.
• Simplified Integration: The 998100024 kit includes the essential solenoid and sensor components required for a standard field installation or retrofit.
• Operational Stability: Reduces the risk of nuisance trips on high-limit switches during extreme ambient conditions.

Common Technical Questions:

What does the Demand Cooling Kit monitor?
The module senses the discharge temperature via a thermistor and modulates the injection of refrigerant to keep the head temperature below the critical 310°F threshold.

Is this kit compatible with 4D R-448A/R-449A retrofits?
Yes, this Copeland 240V demand cooling system is frequently required when retrofitting older 4D systems to newer HFO blends to manage the higher discharge temperatures associated with these refrigerants.

Does this replace a head fan?
In many low-temp applications, Demand Cooling is used instead of or in conjunction with head fans to provide more direct cooling to the internal motor and valve plate area.
