Yes, MI Series is accuracy-designed to be fully compatible with all major VRF/VRV systems. Our joints meet exact OEM specifications to ensure seamless integration, optimal refrigerant flow, and reliable performance in both new installations and existing system architectures for consistent results.

Our 100% leak-proof guarantee comes from high-precision CNC machining, ensuring perfect seam integrity, followed by a mandatory 6.0 Mpa pressure test on every single unit. This exceeds standard industry tests, providing a dual-process validation that guarantees reliable, leak-free operation for the joint's entire lifetime under all real-world system pressure conditions.

Yes. Our normal insulation is the self-extinguishing UV-stabilized fire-retardant XPLE, which is of high safety standards. In projects that have more rigid codes, we will provide optional insulation with higher fire ratings. This guarantees maximum adherence to international safety standards in commercial, high-rise and other vital building projects that need certified fire-safe materials.

The laser-etched traceability marking provides a unique code for each joint, enabling complete tracking back to its production batch, copper source, and pressure test records. This offers verifiable documentation for warranties, simplifies maintenance audits, and adds a layer of quality accountability that we fully stand behind as the manufacturer.

Precision-bored smooth internal pathways of our joints enhance VRF efficiency, which reduces turbulence and pressure drop. This is to ensure the optimum distribution of refrigerant to all indoor units to enable them to work to their intended capacity. This minimizes the compressor load and the overall energy performance and operational efficiency of the entire system.

We maintain a strategic inventory of standard configurations for quick dispatch. In large-scale or custom manufacturing, our special manufacturing line provides efficient turnaround. When our sales team reviews the project, you will receive firm, reliable timelines that fit within your construction schedule, which will not delay critical path installation work by having the materials available.

Yes, customization is one of the main competencies. We design and manufacture custom header systems, special pipe size reducers, and custom joint designs to fit into intricate system designs or older equipment interfaces perfectly. This will guarantee maximum compatibility and performance without any reduction in our high standards of material quality or manufacturing.

Our 6.0 Mpa (870 psi) test is 5.2 Mpa higher than our competitors, and it subjects all the components to loads which are much higher than those encountered in normal operation. This high level of validation gives it a higher safety factor, integrity of critical applications and better durability and long term reliability to hard commercial installations.

MI Series products are ROHS, CE and REACH compliant. Our production plant has a certified Quality Management System (QMS) that guarantees a steady production standard. We also offer all the relevant material, certification and compliance documentation needed in professional project submissions and regulatory approvals in the international markets.

Our after-sales services involve troubleshooting. For large projects, we offer on-site project advice to ensure optimal installation practices. We also assist with product purchase, through to commissioning and handover of the final system.
