The DA Series VRF/VRF Systems kit is a Refrigerant Branch Piping kit used to accurately split the flow of R410A refrigerant from one outdoor unit to multiple indoor units. It is essential for creating the piping network in any multi-zone VRF/VRV installation.

Yes, its Multi-Step design allows the VRF DA Series Y-Joints to be compatible with multiple OEM systems. The kit includes reducers to adapt to various standard pipe sizes used by different manufacturers, making it a versatile, universal solution.

Every single DA Series Ref Joint is individually pressure tested at 5.2 MPa using an inert gas, a standard far exceeding normal operating pressure. This 100% testing protocol guarantees a leak-proof seal before the product leaves our factory.

We offer a choice of three insulation types to suit project needs: EPS for cost-effectiveness, fire-retardant UV Stabilized XLPE, and flexible NBR. This includes options for VRF/VRV Copper Separation Tube insulation as part of customized solutions.

227 Enterprise is a top-tier manufacturer and supplier. We design, engineer, and manufacture the DA Series in-house, ensuring complete control over quality, and also supply directly to contractors and OEMs, guaranteeing authenticity.

Unlike general metal goods suppliers, we specialize exclusively in precision HVAC components. Our focus as VRF/VRV Refnuts Manufacturers in India translates to deeper technical expertise, higher quality standards, and dedicated support for complex VRF projects.

Absolutely. As a leading VRF/VRV Copper Multi Kit Manufacturer, we regularly engineer Customised Premium VRF Copper Joints, including specialized VRF/VRV Branch Piping Fittings and separation tubes to meet unique architectural or system design requirements.

Our DA Series is ROHS & CE Compliant, meeting essential health, safety, and environmental standards. We provide full certification documentation, which is crucial for projects in the Middle East, Europe, and other regulated markets.

High-purity, phosphorus-deoxidized copper ensures excellent thermal conductivity, durability, and, most critically, proper brazing. Inferior copper can lead to joint failures, leaks, and system breakdowns, which is why we source only certified materials.

The precisely designed internal geometry of our Y-Joints minimizes refrigerant turbulence and pressure drop. This balanced flow ensures each indoor unit receives the correct refrigerant charge, allowing the entire system to operate at its designed efficiency.
