Product Faqs

What is a ME Series Branch Joint and How Does it Work?

ME Series Branch Joint is a refrigerant distribution joint for Variable Refrigerant Flow (VRF) air conditioning systems. It guides refrigerant from the main pipeline to several interior units to balance refrigerant flow, stabilize system pressure and improve cooling efficiency. ME Series Branch Joints are developed for precision and reliable operation, contributing to total HVAC system efficiency and long-term performance.

How to select the right ME Series Branch Joint for your VRF system?

Choosing the Right ME Series VRF Branch Joint Is Easy 227 Enterprise makes ME Series Branch Joints compatible with OEM equipment, and model numbers meet the criteria of the major VRF manufacturers. The correct branch joint can be identified by looking at the model number in your Single Line Diagram (SLD), project drawings, or equipment schedule. Or, you can match the inlet and exit pipe sizes to the dimensions given in our product catalog or technical requirements to get the right model. Our technical team is available to help you choose the proper branch junction for your HVAC project if you need assistance.

The ME Series Branch Joints are compatible with the following refrigerants

227 The Enterprise ME Series Branch Joints work with R410A and R32 refrigerants, which makes them perfect for VRF air conditioning systems of today. Our ME Series VRF Branch Pipes are manufactured to OEM requirements for efficient refrigerant distribution, leak-free performance and reliable operation in commercial, industrial and residential HVAC systems.

The ME Series complies with international quality standards.

The quality management system applied to production of the Enterprise ME Series Branch Joints is quite strict and they meet internationally accepted standards. Our products are ISO Certified, CE Compliant, RoHS Compliant and Certified to AS 4041:2006 (Pressure Piping Applications). Each ME Series Branch Joint is built to OEM specifications and hydrostatic pressure tested and quality inspected to provide reliable performance, leak-free operation and long-term durability for commercial, industrial and residential VRF HVAC systems.

What is the copper grade used for manufacturing ME Series Branch Joints?

227 Enterprise ME Series Branch Joints are made from high quality DHP (Phosphorus-Deoxidized) refrigeration grade copper as per BIS specifications. The high quality copper provides outstanding thermal conductivity, corrosion resistance and durability to ensure efficient flow of refrigerant and reliable leak-free operation in modern VRF air conditioning systems. All branch joints are built to OEM specifications with precision, pressure tested hydrostatically and undergo rigorous quality inspections before shipment.
