Copeland 998-1001-23 Demand Cooling Kit

The Copeland 998-1001-23 Demand Cooling Kit is the OEM Demand Cooling retrofit kit for 3D Discus compressors running on 240V, 50Hz power — the international-frequency counterpart to the 998-1000-23 kit used on 60Hz systems. Demand Cooling monitors compressor discharge temperature and injects liquid refrigerant back into the compressor only when needed, protecting against high-discharge-temperature damage on low-temperature and high-compression-ratio applications without the constant-injection efficiency penalty of older fixed-bleed systems.

Per Copeland's official Demand Cooling kit documentation, the 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 complete installation and troubleshooting guide. Copeland's part-number matrix places this kit alongside 998-1001-13 (2D), 998-1001-14 (4D), and 998-1001-16 (6D) as the 50Hz/240V family, and its 60Hz equivalent for the same 3D/240V combination is 998-1000-23. An optional 998-0700-09 mounting bracket is available for 2D and 3D module installations that lack a factory mounting point.

Key Benefits

• Exact 3D/240V/50Hz Match: Specified by Copeland for 3D Discus compressors on 240V, 50Hz power — the correct kit for 50Hz installations, not a substitute for the 60Hz 998-1000-23.
• 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: On-demand refrigerant injection reduces compressor damage risk on low-temp and high-compression-ratio systems.
• Documented Part Family: Cross-referenced in Copeland's own kit matrix against 998-1001-13 (2D), 998-1001-14 (4D), 998-1001-16 (6D), and the 60Hz equivalent 998-1000-23.

Common Questions

• How is this different from 998-1000-23? Both are 3D Discus, 240V Demand Cooling kits; 998-1001-23 is the 50Hz version and 998-1000-23 is the 60Hz version. Installing the wrong frequency kit will not correctly protect the compressor.
• 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.
• How do I know if my system is 50Hz? Check the compressor and system nameplate for frequency rating — 50Hz is standard outside North America. Confirm before ordering, since 50Hz and 60Hz Demand Cooling kits are not interchangeable.
