Product Description
The Copper Tube Accumulator (Muffler) is a critical refrigeration component designed to protect the compressor and improve the overall performance of household and commercial refrigerators, freezers, and small cooling systems.
Its primary function is to collect and store excess liquid refrigerant, ensuring that only vapor enters the compressor, which prevents compressor slugging, reduces noise, and extends the life of the refrigeration unit.
Constructed from premium-grade copper tubing, this accumulator provides excellent thermal conductivity, corrosion resistance, and durability. Its compact design allows for easy integration into different refrigerator models, making it suitable for OEM manufacturing and maintenance replacements.
Product Features & Advantages
-
Compressor Protection – Prevents liquid refrigerant from returning to the compressor, avoiding internal damage and extending equipment lifespan.
-
Noise Reduction – Acts as a muffler to reduce vibration and operating noise, ensuring quieter refrigeration performance.
-
High Thermal Efficiency – Copper construction ensures fast heat transfer and stable operation, improving system efficiency.
-
Corrosion & Leak Resistant – High-purity copper provides superior resistance to oxidation and refrigerant corrosion.
-
Versatile Application – Compatible with common refrigerants (R134a, R600a, R404A, R22, etc.) used in refrigerators, freezers, and small air-conditioning units.
-
OEM & Replacement Ready – Ideal for both original equipment manufacturing and aftermarket repairs.
