Copeland 998-1000-23 Demand Cooling Kit

The Copeland 998-1000-23 Demand Cooling Kit is the OEM Demand Cooling retrofit kit for 3D Discus compressors, built for 240V, 60Hz systems. Demand Cooling is Copeland's discharge-temperature protection strategy: rather than running a fixed liquid-injection bleed continuously, the system's demand cooling module monitors discharge temperature and injects liquid refrigerant back into the compressor only when it's actually needed, protecting the compressor from high-discharge-temperature damage on low-temperature and high-compression-ratio applications without the efficiency penalty of constant injection.

Per Copeland's own kit documentation, this kit includes the demand cooling module with two mounting screws, a temperature sensor with 3’ shielded cable, the injection valve and solenoid (mounting hardware not included), and a full installation and troubleshooting guide. Neuco's own parts breakdown for this kit lists the 023-0042-02 solenoid coil, the 510-0349-03 expansion solenoid valve assembly, and the 985-0110-01 240V compressor protector as the individually serviceable components inside it. It sits alongside the 998-1000-22 (2D compressor) and 998-1000-24 (4D compressor) kits in the same 240V/60Hz Demand Cooling family, and its 50Hz counterpart for the same 3D/240V combination is part number 998-1001-23. An optional 998-0700-09 mounting bracket is available for 2D and 3D module installations where the compressor doesn't provide a factory mounting point.

Key Benefits

• Exact 3D/240V/60Hz Match: Specified by Copeland for 3D Discus compressors on 240V, 60Hz power — not a universal demand cooling kit.
• Complete Kit: Includes the demand cooling module, temperature sensor with shielded cable, and injection valve and solenoid in one order.
• Protects Against High Discharge Temperature: Injects refrigerant only on demand, reducing the risk of compressor damage on low-temp and high-compression-ratio systems.
• Documented Part Family: Cross-referenced against 998-1000-22 (2D), 998-1000-24 (4D), and the 50Hz equivalent 998-1001-23, so the correct kit for a different compressor size or frequency is easy to identify.

Common Questions

• What compressor and power supply is this for? Copeland 3D Discus compressors running on 240V, 60Hz power. For 50Hz systems, the equivalent kit is 998-1001-23.
• What's included in the kit? The demand cooling module with mounting screws, a temperature sensor with 3-foot shielded cable, the injection valve and solenoid, and an installation/troubleshooting guide. Mounting hardware for the injection valve is not included.
• Do I need a separate mounting bracket? If the compressor doesn't have a factory mounting point for the module, the 998-0700-09 bracket (2D/3D models) is available separately.
