Copeland 910-0349-04 Demand Cooling Injection Valve 120V for 3D Style Compressors

The Copeland 910-0349-04 is a demand cooling injection valve designed for use with Copeland 3D style semi-hermetic refrigeration compressors. This critical component works in conjunction with a demand cooling control module to protect compressors from high discharge temperatures in low-temperature refrigeration applications.

Key Features:

• 120V solenoid coil for reliable operation
• Engineered specifically for 3D Copeland Discus compressors
• Automatically injects saturated refrigerant into compressor suction when discharge temperatures exceed safe limits
• Essential for low temperature R-22, R-407A/C/F/H, R-448A, and R-449A applications
• Durable construction for long service life in commercial refrigeration systems

How It Works:

When the demand cooling module detects excessive compressor discharge temperatures, it energizes this injection valve to meter a controlled amount of saturated liquid refrigerant into the compressor suction cavity. This process rapidly reduces discharge temperatures to safe operating levels, protecting the compressor from thermal damage and extending equipment life.

Applications:

Commonly used in commercial refrigeration systems including supermarket refrigeration racks, walk-in freezers, and other low-temperature applications where compressor discharge temperatures can exceed normal operating ranges. Compatible with various refrigerants including R-22, R-404A, R-407 series, R-448A, and R-449A.
