What is the ME Series, and what does it include?

The ME Series is a pre-engineered refrigerant branch piping kit for VRF systems. Each kit includes precisely matched liquid and suction copper tee joints and all necessary reducer connectors, designed for easy, leak-proof installation with R410A refrigerant

Are ME Series joints compatible with my existing VRF system?

Yes. The ME Series is designed for universal compatibility with all major VRF system brands operating on R410A refrigerant. The kits are precision-manufactured to meet standard OEM specifications for seamless integration.

How do your joints ensure a leak-proof connection?

Every single ME Series joint is individually pressure tested at 5.2 MPa (over 750 psi) before shipment. Combined with precision-machined surfaces and the use of high-quality brazing alloys, this guarantees a perfect, durable seal

What are the benefits of using your pre-assembled kits over sourcing separate parts?

Our kits eliminate guesswork and error. You receive perfectly matched components, reducing on-site brazing by up to 80%. This accelerates installation, minimizes contamination risk, and ensures a correct refrigerant flow balance from the start.

What insulation options are available, and why does it matter?

We offer both XPLE and premium insulation. Proper insulation is critical to prevent condensation ("sweating") on pipes, which reduces energy loss, maintains refrigerant temperature, and protects building interiors from water damage.

Are these products certified for international projects?

Absolutely. The ME Series is ROHS and CE compliant, meeting stringent international safety and environmental standards. This makes them suitable for export and use in regulated projects worldwide without compliance concerns.

Why choose copper over other materials for VRF joints?

Copper offers unmatched durability, superior corrosion resistance, and excellent thermal conductivity. It is a 99.9% pure, lead-free material that ensures system longevity, safety, and long-term reliability, making it the industry standard for critical refrigerant lines

How does using your product impact overall VRF system efficiency?

Precisely balanced refrigerant flow is key to VRF efficiency. Our joints are engineered for precise distribution, preventing uneven cooling and heating, as well as reducing compressor strain. This helps maintain the system's designed SEER rating and optimal energy consumption

Can you provide custom configurations for unique project requirements?

As a top-tier manufacturer, we specialize in customized solutions. We can engineer ME Series kits to meet non-standard sizes or specific project configurations. Contact our technical team with your project schematics for a tailored quote.

What is your lead time, and do you offer volume discounts?

We maintain stock for standard kits for quick dispatch. For large project volumes and custom orders, we offer competitive tiered pricing. Please reach out via the contact form for a specific quote based on your quantity and delivery timeline.
