Copeland 910-0349-05 Valve Kit

The Copeland 910-0349-05 Demand Cooling Valve Kit is an essential component for low-temperature refrigeration applications using R-22, R-407A, R-407F, or R-448A/R-449A. This system proactively manages discharge line temperatures by injecting a metered amount of liquid refrigerant into the suction gas. By maintaining the compressor within safe thermal operating limits, the 910-0349-05 kit prevents oil breakdown and internal component failure during high compression ratios. This kit is specifically designed for Copeland Discus compressors and includes the injection valve, electronic control module, and the necessary thermistor sensors. Proper installation of this liquid injection valve ensures that the system does not exceed the 280°F critical temperature threshold, which protects the valve plates and cylinders from carbonization and excessive wear in demanding industrial environments.

• Thermal Protection: Actively monitors discharge gas temperature to prevent compressor overheating in low-temp settings.
• Refrigerant Compatibility: Optimized for use with modern HFO blends and traditional HCFC/HFC refrigerants.
• Precision Metering: Delivers exact liquid quantities through the solenoid injection valve to stabilize internal thermals without liquid slugging.
• System Reliability: Extends the service life of the Copeland compressor by maintaining lubricant viscosity and integrity.

Common Technical Questions

What triggers the injection process in this kit?
The module monitors the discharge temperature via a sensor; the Demand Cooling cycle activates once the probe detects temperatures climbing toward the compressor’s safety limit, opening the solenoid to cool the suction gas.

Can this kit be installed on any semi-hermetic compressor?
No, the 910-0349-05 is engineered specifically for Copeland Discus models equipped with the appropriate injection ports and head configurations.

Does this kit require a separate transformer?
Check your specific control voltage; most Copeland Demand Cooling modules require a dedicated 24V or 120V/240V power source depending on the specific module version included in the valve kit.
