Balanced refrigerant flow, leak-proof joints, and dimensional accuracy built into every TRN Series branch — so your TRN VRF system runs the way it was designed to, zone after zone.
VRF system branch fittings are important. Here, refrigerant distribution impacts the operation of each indoor unit. 227 Enterprise Pvt. Ltd. TRN Series is built exclusively for VRF applications, with Y-joints and reducers suited to VRF branch-selector specifications and capacity tiers. The TRN Series is constructed from premium refrigeration-grade, nitrogen-purged copper. It is compatible with R410A and R32 Refrigerant, all joints are pressure tested to 5.2 MPa / 754 PSI utilising hydrostatic and inert-gas testing. That means reliable, leak-proof installation with fewer field joints, less brazing and faster start-up.
TRN Series kits are offered with XLPE or NBR insulation as per the client requirement, to help reduce condensation, thermal bridging and refrigerant heat gain along the branch lines for long term performance. These features help deliver consistent refrigerant flow, greater energy efficiency and decreased maintenance needs for residential, commercial and industrial VRF applications. With RoHS and CE certifications, the TRN Series provides the perfect balance of precision engineering, material quality, safety and dependable performance for demanding HVAC applications.

In a VRF system, no fitting functions in isolation – each branch component has to prove its worth in the overall balance of refrigerant flow, and that’s precisely the criterion the TRN Series from 227 Enterprise Pvt. Ltd. is designed to satisfy. Its Y-joints and reducers are sized with the type of precision that takes the guesswork out of installation, so fittings seat cleanly, connections hold under pressure and crews spend less time making modifications on site. That reliability begins with the material: premium refrigeration-grade copper, purged with nitrogen before it ever gets to a job site, compatible with R410A, and pressure tested to 5.2 MPa (754 PSI) by hydrostatic and inert-gas methods, so every joint earns its place in the system, not just passing inspection. Add optional XLPE or NBR insulation to keep condensation and heat transfer in check, along with RoHS and CE certification for those projects that require documented compliance, and what you have is a branch piping solution consultants can specify with confidence, contractors can install without friction and building owners can count on to perform quietly for years after the ceiling goes back up.
