Products Description

HVAC Compressor Silencers & Acoustic Mufflers

Advanced NVH Control

Strategically installed at compressor inlet/outlet ports and one-way valves, our copper acoustic mufflers are designed for demanding noise, vibration, and harshness (NVH) control. They act as highly effective silencers, dampening refrigerant gas pulsations and ensuring smooth, quiet operation for air conditioning and refrigeration units.

Product Features
  • Superior Noise Dampening: The precisely engineered expansion chamber and internal geometry effectively absorb acoustic energy and cancel out high-frequency noise from the compressor.
  • Advanced Hydroforming & Spinning: Manufactured using state-of-the-art metal forming processes. This creates a seamless, one-piece copper body with no internal weld seams, maximizing durability.
  • Vibration Reduction: By smoothing the flow of high-pressure gas, these mufflers reduce overall system vibration, preventing fatigue failure in surrounding copper piping.
  • High-Pressure Reliability: Built to withstand the extreme pressures of modern refrigerants (like R410A and R32), featuring a certified burst pressure of ≥13 MPa.
Application Scope
  • Applications: Compressors, one-way valves, and branch pipe connections in refrigerators, AC units, and heat pumps.
  • Burst Pressure: ≥ 13 MPa
  • Applicable Refrigerants: R134a, R22, R407C, R410A, R32, etc.
  • Operating Temperature: Suitable for standard HVAC operational ranges.

Q:1.Do you provide CE/UL certificates for the entire kit?

A: We provide UL/CE certified modules (like filter driers and charge valves) sourced directly from top-tier manufacturers. The certificates and test reports for these specific components come with the shipment. For non-electrical parts (like copper pipes and brackets), we provide material reports and d

Q:2.Are electrical cables included in the kit for the local market?

A: No. To ensure strict compliance and avoid regional electrical certification conflicts (such as CE/UL cable standards), electrical cables are intentionally excluded from our standard mechanical kits. This allows you to source local, fully certified cables and integrate them on your line, keeping your

Q:3.What exactly is included in your standard "Line Set Kit"?

A: Our standard kit includes five core mechanical modules: Y-Joints (or tees), pre-cut copper pipes with insulation, filter driers, charge valves, and vibration eliminators. Optional modules like sight glasses or accumulators are available upon request. We pack them according to your specific machine B

Q:4.Can you customize the copper pipe lengths and kit composition?

A: Yes. Because we aggregate from a flexible, top-tier supply chain, we can customize the copper pipe lengths (pre-cut and flared), insulation thickness, and the specific combination of components based on your exact assembly drawings. You don't need to meet a massive MOQ for the whole kit; we scal

Q:5.How do you handle the shipping and customs clearance documents?

A: Since a kit involves multiple HS codes (copper fittings, valves, brackets), we coordinate the commercial invoice and packing list clearly by item. We work closely with your freight forwarder to ensure the customs declaration matches the physical goods exactly, minimizing the risk of port delays. All

Q:6.What is the typical lead time for a BOM-matched kit?

A: After BOM confirmation and sample approval, the production of the core modules typically takes 20–30 days. Because we consolidate modules at our facility before shipping, you save the time you would normally waste waiting for different factories to deliver to your forwarder. We provide a single, un
