Products Description

Flow-Stabilizing HVAC Copper Silencers

Product Overview

Installed at compressor inlet/outlet ports, one-way valves, and piping branches, our copper silencers are designed to optimize system flow dynamics. They effectively absorb high-frequency noise and, more importantly, smooth out the aggressive gas pulsations generated by the compressor, creating a stable operational environment for your air conditioning equipment.

Key Engineering Advantages
  • Flow Dynamics Optimization: By dampening pressure spikes and gas pulsations, these mufflers protect the compressor from internal stress and ensure a steady refrigerant flow throughout the circuit.
  • Advanced Hydroforming Technology: Created using state-of-the-art hydroforming and spinning processes. This results in a seamless, one-piece structure without internal welding defects, ensuring superior fatigue resistance.
  • Eco-Friendly & Economical: Our highly automated production process minimizes material waste and energy consumption, providing a sustainable and cost-effective solution for large-scale AC manufacturing.
  • Exceptional Burst Pressure: Rigorously tested to withstand high-pressure refrigerants like R410A and R32, with a guaranteed burst pressure of no less than 13 MPa.
Application Scope
  • Applications: Compressor connections, valve assemblies, and branch piping in air conditioners, refrigerators, and heat pump systems.
  • Burst Pressure: ≥ 13 MPa
  • Applicable Refrigerants: R134a, R22, R407C, R410A, R32, etc.

* Note: Standard specifications are listed above. We offer custom manufacturing (including dimensions and integrated components) based on your technical requirements.


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
