Copeland 998-1000-22 Demand Cooling Kit

The Copeland 998-1000-22 Demand Cooling Kit is a critical management system designed specifically for 2D Discus compressors operating in low-temperature applications. Engineered for 240V 50/60Hz configurations, this kit actively monitors discharge temperatures to prevent thermal breakdown of refrigeration oil—a common failure point when utilizing R-22 or newer HFC/HFO blends like R-407A and R-448A. Unlike standard head fans, this liquid injection system utilizes a precise injection valve and temperature sensor to deliver metered refrigerant directly into the suction gas. This process effectively maintains internal temperatures below the critical 225°F threshold, ensuring compressor reliability and system stability during high compression ratio cycles. As a complete OEM replacement kit, it includes the demand cooling module, a 3-foot shielded sensor cable, and the necessary solenoid components to restore factory-standard protection to your refrigeration rack.

Key Benefits

• Precision Thermal Protection: Actively prevents oil carbonization by maintaining discharge temperatures within safe operating limits.
• Broad Compatibility: Supports dual frequency (50/60Hz) and is specifically calibrated for Copeland 2D compressors.
• Comprehensive Kit: Includes the demand cooling module, temperature probe, injection valve, and solenoid for a complete field installation.
• Enhanced Efficiency: Optimizes compressor performance under high-load, low-SST conditions without the need for excessive mechanical cooling.

Common Questions

When is demand cooling required for a 2D compressor?
Demand cooling is essential for low-temperature applications where suction temperatures and compression ratios lead to discharge temperatures exceeding 225°F. It is practically mandatory for R-22 low-temp systems and recommended for many modern HFC retrofits.

How do I troubleshoot a triggered demand cooling module?
Technicians should first verify voltage at the L and M terminals. If the module is powered but the solenoid isn't energizing, check the ohms on the temperature sensor and inspect the injection valve orifice for debris. Ensure a 25-micron liquid line filter drier is installed upstream.

Can this kit be used on 3D or 4D models?
No, this specific kit (998-1000-22) is engineered for the internal geometry and injection ports of the 2D compressor body. Other models require different kit numbers to ensure proper fitment and injection rates.
