Copeland 577-0415-04 Tank Assembly

The Copeland 577-0415-04 Liquid Receiver Tank Assembly is a critical management component engineered for high-pressure commercial refrigeration systems. This heavy-duty steel vessel functions as the primary reservoir for liquid refrigerant, ensuring a consistent, solid column of liquid reaches the expansion device regardless of varying load conditions. As a direct replacement for 577-0415-00, this assembly maintains HVACR system stability by storing excess charge during low-load periods and protecting the compressor from liquid slugging. Built to withstand rigorous industrial cooling environments, it features a 1/4 inch flare connection, a 3/8 inch inlet, and a durable vertical orientation with a weight of approximately 8.5 lbs.

Key Benefits:

• System Pressure Regulation: Actively balances mass flow fluctuations to maintain optimal refrigerant head pressure.
• Compressor Protection: Prevents hazardous liquid refrigerant from entering the suction line, mitigating the risk of valve damage.
• Pump Down Capability: Provides sufficient internal volume to hold the system charge during essential maintenance and service procedures.
• Enhanced Efficiency: Traps non-condensable gases at the top of the tank to prevent heat transfer interference in the condenser.
• OEM Compatibility: Designed specifically for Copeland condensing units, ensuring exact fitment and port alignment for fast field installation.

Common Questions:

In a standard refrigeration circuit, this tank must be positioned on the liquid line, immediately following the condenser outlet and before the liquid line filter-drier or expansion valve.

No. This is a high-pressure liquid receiver designed to store liquid after condensation. A suction accumulator is a low-pressure component installed before the compressor inlet to prevent liquid floodback.

The 577-0415-04 is the manufacturer-designated direct replacement. Technicians should verify fitting sizes and mounting footprints, as this assembly utilizes standard 3/8" and 1/4" connections common in commercial racks.
