LG Series

LG Series Y Branches – OEM matched, pressure tested and built so you only see how little there is to see on site.

"One Less Thing to Worry About on Site."

The 227 Enterprise, LG Series makes that connection easy and reliable. Precision-engineered copper Y-joints for suction and discharge lines and matching reducers are included in each kit to help installers achieve perfect fitment with less on-site brazing. There are fewer connections in the multi-step design for a cleaner, faster installation that is less likely to need changes or rework.

The attention to detail is more than what you see. Designed to assist protect against moisture and sweating in severe settings, the LG Series features UV-stabilised, fire-grade XLPE and premium NBR insulation options. The joints are brazed under nitrogen purging to minimize internal oxidation, and individual traceability markers make it easier to identify production and quality records if required. The LG Series is designed for commercial and industrial VRF applications. It’s about getting the details right so when the system is installed and operating, you have one less thing to worry about.

Why 227 Enterprise

The LG Series is backed by the kind of quiet infrastructure most buyers don’t notice until it’s not there: strict quality control on every batch, product traceability back to the joint it shipped from, technical support from people who know the drawing you’re working from, and customization when your project doesn’t fit a catalog size.

When you choose 227 Enterprise, you are not just choosing a component, you are choosing a supply chain that delivers on time, a manufacturing partner who picks up the phone after the sale, and precision-engineered solutions that are designed for the long, unglamorous middle of a project’s life, not just the day it’s installed. It’s what LG Series was built to give and what long-term HVAC performance is all about.
