Precision-Engineered VRF Y Joints: Leak-Proof Connections for Multi-Zone Systems

A Variable Refrigerant Flow (VRF) system will make use of as much efficiency as possible by pumping a fixed amount of refrigerant needed in a single cycle. It provides you with concurrent, autonomous regulation of climate control over a number of zones with a single external unit.

VRF Branch Piping has a multi-step design that is applicable to all major brands of R410A. All joints are fitted standard with UV-stabilised fire-grade XLPE insulation to remove condensation. It is also 100 percent pressure tested at 5.2 Mpa, which ensures that there is no leakage in the connections and long term integrity.

Why 227 Enterprise

We provide system assurance, unlike other companies which sell components. Our 10 years of specialisation mean that we do not only design to the specification, but to actual performance and long life. Every Y-joint has our proprietary tooling and multiphase quality inspection, such as ultrasonic cleaning and traceability marking. This leads to decreased overall cost of ownership: fewer callbacks, reduced energy waste, and less loss of refrigerant. Install with us fittings that you only need to install and forget.

Why would our VRF branch pipe be compatible with other OEM systems?

For our VRF branch piping kits, lead times vary depending on the product type. Our standard, OEM-compatible kits are typically ready for dispatch shortly after order confirmation. For fully bespoke, made-to-order solutions, the process involves design, manufacturing, and testing, which requires a longer lead time. We provide clear timelines for every project and maintain communication throughout the process to ensure reliable delivery without compromising on our high standards of quality.

What does the 5.2MPa pressure test do to my VRF system?

The joint is tested in extreme conditions, as the factory test is way over the normal operating pressures. It identifies the possible failures at an early stage, detecting pressure spikes and vibration. The outcome is decades of leak-free and reliable performance that maintains the efficiency and longevity of your system since the first day.

What is the benefit of UV-stabilized, fire-grade XLPE insulation?

This high-quality insulation prevents condensation (commonly referred to as sweating), which is a source of energy waste, and in addition may destroy water-sensitive surfaces. Its UV and fire resistance ensure that it does not tear up in the open or harsh environment. The outcome would be uniform thermal efficiency, enhanced safety and extended dexterity of your VRF system.

Do you offer customized branch piping packages to particular project designs?

Yes. We are experts in tailored engineering. It is with your CAD drawings that we design custom kits: with special headers, lengths, and angles, which are unique to tricky constructions. This best fit accelerates set-up, does away with on-site adjustment timeframes, and provides an accurate and cost-effective answer to non-standard or architecturally challenging projects.

Which quality certifications do you have on your manufacturing processes?

We adhere to ROHS, CE, and ISO 9001: 2015. All copper lots are certified mills, and all production runs are documented to have passed quality checks. These global standards are used to guarantee uniform, dependable and conforming products for local or international projects.

How long is your standard and custom branch piping kit lead time?

Kits that are compatible with Standard OEM are shipped within 7-10 working days. Bespoke solutions take 34 weeks to design, manufacture, and test. We are very clear on timelines, remain on track with you and retain quick turnaround without compromising on quality.

What will guarantee you 100-percent leak proof connection?

Our process incorporates high-purity Cu-DHP copper, CNC machining, and brazing of proprietary alloys under nitrogen atmospheres. Each joint is, then, verified by means of a helium mass- spectrometer test with a hermetic seal that is guaranteed to last as long as the system is active.

Do you use your branch piping with the newer refrigerant R32 as well as with R410A?

Yes. Our products are future-proofed. Cu-DHP copper of high grade, strong brazing, and insulation are both compatible and work very well with R410A and R32. They provide the best performance, safety, and reliability in contemporary as well as next-generation system designs.

What backup do you provide in regard to site installation issues?

We provide step-by-step installation guides, technical data sheets and direct accessibility to our engineering department. On-call support or video guidance in order to troubleshoot situations is also offered by us when dealing with major projects. We aim at first-time and error-free installation of our products, within the design specification.

Why is the use of your precision joints better than using the basic VRF system?

Refrigerant flow is balanced by smooth, turbulence-free bores achieved by precision machining. This minimizes pressure drop,s enabling compressors to operate at optimum efficiency. The result includes a decrease in the energy consumption, the cost of electricity, and the operating expenses throughout the life of the system, and the maintenance of uniform comfort in all areas.
