What exactly are ‘customised components’ in VRF systems?

Customised components are copper fittings—such as Y‑joints, tees, manifolds, headers, and 3D‑bent tubes—that are specifically engineered to match unique project layouts or OEM specifications. Unlike off‑the‑shelf parts, they are designed to fit exact pipe sizes, connection angles, and space constraints, ensuring a perfect, leak‑free integration in complex multi‑zone VRF/VRV piping networks.

Are your custom copper components compatible with all major VRF brands?

Yes. Our multi‑step design allows a single component to adapt to multiple pipe sizes used by different manufacturers. We engineer parts to be universally compatible with brands like Daikin, Mitsubishi Electric, Hitachi, LG, and others, reducing the need for separate inventories and simplifying procurement for contractors and OEMs.

How do you guarantee that custom joints are 100% leak‑proof?

Every custom component undergoes individual pressure testing at 5.2 MPa using inert gas, a standard far exceeding normal operating pressures. This 100% testing protocol, combined with high‑silver BCuP‑6 brazing and precision machining, ensures a perfect seal before dispatch, eliminating the risk of refrigerant leaks and subsequent system failures.

What certifications do your custom components carry for international projects?

Our manufacturing facility is ISO‑certified, and our products are ROHS & CE compliant. We provide full certification documentation, including material test certificates and pressure‑test reports, which are essential for projects in regulated markets like the Middle East, Europe, and Australia, ensuring compliance with health, safety, and environmental standards.

Can you create a custom component from just a drawing or sample?

Absolutely. We specialize in translating drawings, samples, or even rough sketches into production‑ready components. Our engineering team reviews your requirements, suggests optimizations, and produces prototypes for approval, ensuring the final product meets your exact technical and performance specifications before full‑scale manufacturing begins.

What is the typical lead time for a customised order?

Lead times vary based on complexity and volume. Prototypes can often be delivered within 2‑3 weeks, while bulk production orders typically take 4‑6 weeks. We maintain transparent communication throughout the process, providing regular updates to ensure your project timeline is met without compromise.

Do you have a minimum order quantity (MOQ) for custom components?

No. We cater to both low‑volume prototype requests and large‑scale production runs without enforcing a minimum order quantity. This flexibility allows consultants and contractors to order exact quantities needed for specific projects, reducing waste and inventory costs.

Why is the quality of copper so critical in VRF fittings?

High‑purity, phosphorus‑deoxidized copper ensures excellent thermal conductivity, durability, and, most importantly, proper brazing. Inferior copper can lead to joint failures, leaks, and system breakdowns. We source only certified, high‑grade copper to guarantee the longevity and reliability of every component we manufacture.

What support do you provide during installation?

We offer detailed installation manuals, technical datasheets, and direct access to our engineering team for any on‑site queries. For large projects, we can also provide supervised installation support to ensure our custom components are integrated correctly for optimal performance.

What sets 227 Enterprise apart from other copper component suppliers?

Unlike general metal goods suppliers, we specialize exclusively in precision HVAC&R copper components. This focused expertise, combined with in‑house design, manufacturing, and 100% testing, translates to deeper technical knowledge, higher quality standards, and dedicated support for complex VRF projects, making us a trusted partner for OEMs and contractors globally.
