What is the main benefit of the multi-step design of the AX Series?

The stepped design allows different pipe sizes to connect gradually instead of abruptly. That smooth transition keeps refrigerant flow steady, avoids pressure drops, and helps every indoor unit receive the right share, which in turn reduces compressor stress and keeps the system running reliably.

Do AX Series kits work with the major VRF brands?

Yes, they are made to match the connection standards used by leading VRF manufacturers. This means contractors can fit them into existing layouts without adjustments and use the same solution across projects, regardless of the VRF brand involved.

What is the 5.2MPa pressure testing that ensures the system is leak-proof?

Each piece is tested at a pressure well above normal operating conditions. Holding it at 5.2MPa confirms the strength of the copper and the brazed joints, so only components that are completely tight and structurally sound are supplied for installation.

What are the insulation choices on the AX Series Branch Piping Kits?

The kits come with factory-fitted insulation such as NBR for condensation and fire safety, XLPE for stable thermal performance, and other options when a project calls for them. Since it is pre-applied, site work becomes faster and the insulation quality stays consistent.

Does 227 Enterprise produce these VRF components or does it sell them?

These are manufactured in-house. From forming the copper to testing and insulation, everything is handled within the company’s own production setup, which allows better control over quality, consistency, and delivery timelines.

Do you offer custom-designed kits on special project layouts?

Yes, the kits can be built around the actual piping drawing. Required pipe sizes, reducer combinations, and branch directions are planned in advance so the installation follows the design without cutting, reworking, or making adjustments on site.

What are the international export project certifications of your products?

They are produced under certified quality systems and comply with widely accepted international requirements for material safety, pressure performance, and environmental standards, making them suitable for projects that require global approvals and documentation.

How long does it take to get a standard and custom AX Series kit order?

Standard models are generally ready for quick dispatch. For custom kits, the timeline is planned based on the design and quantity, and the delivery schedule is shared early so it fits smoothly into the project execution plan.

Does your product have a warranty, and what is your technical support?

Yes, the products are backed by warranty, and the technical team stays involved from selection and sizing to installation support. This ensures that consultants and contractors always have clear guidance whenever they need it.

What is the overall effect of using the AX Series kit on VRF system efficiency and life?

A well-designed branch connection keeps the refrigerant moving evenly through the network. That balance lowers compressor load, improves energy performance, supports proper oil return, and ultimately helps the VRF system run efficiently for many more years.
