227 Enterprise – VRF Joints and Refrigerant Copper Fittings

CL Series

Refrigerant Branch Piping Kit for all types of VRF Systems working on R410 Refrigerant

In advanced VRF/VRV systems, each outdoor unit is connected to a series of indoor units via refrigerant piping. The part that divides that flow to perfection is the CL Series Refrigerant Branch Piping Kit. It is constructed for R410A and has all the parts running smoothly and steadily in all zones.
Since it features a universal Multi-Step design, it fits nearly any OEM, eliminating the need to carry a multitude of various parts. All joints are pressure-tested to 5.2 Mpa, thus they are literally 100 per cent leak-proof, which makes the system dependable and energy-efficient at all times.

What does the CL Series Branch Pipe do in a VRF system?

The primary work of the CL Series Branch Pipe is to separate the refrigerant from one outdoor unit to all the indoor units. It is this very division that maintains the pressure at equilibrium, the temperatures at all zones and the entire system is highly efficient in energy-saving, that is, it is the mainstay of a solid VRF/VRV installation.

What does the CL Series do to ensure that the joints remain leak-proof?

Each copper Y-joint is manufactured with accuracy and followed by a strict factory pressure test of 5.2MPa. The hard test blots out the weak points, and the seal becomes hard and permanent, and the waste refrigerant is gone, and there is never any more problem with the safety, and the entire installation of VRF is dependable over the long run.

Does the CL Series fit all VRF brands?

Yes, because of its Multi-Step design, which is universal, it will fit the standard pipe sizes of all major VRF manufacturers. That will put in an order of the piece of cake, reduce the number of spare parts you would keep in stock, and allow contractors a ton of freedom on any project without compromising quality or the strength of the system.

What happens when you have refrigerant leakages in VRF branch pipes?

The leaks reduce the system to dumbness, consuming more energy and providing less heating or cooling. And, they are harmful to the environment and may be hazardous. This is why the use of solid and leak-proof parts is a necessity to ensure that the system functions properly, saves money, and fulfils the requirements of the lifespan of the building.

What is the significance of the 5.2 Mpa pressure test?

When a joint has been tested at 5.2 MPa, it means it’s already been taken well beyond normal working pressure to see if it holds. That process checks both its strength and how well it seals. So in day-to-day operation, it continues to run tight and dependable, without the risk of leaks.

Does 227 Enterprise include insulation in the kits?

Yep, condensation may be a pain and a soreness on efficiency, so they provide optional insulation. Choose between fancy XLPE or NBR jackets, which fit the CL Series, to find the right thermal performance to suit any weather or any environment your project requires.

Are these joints applicable to both heat-pump and heat-recovery VRF systems?

For sure. The CL Series is designed to support the refrigerant flow requirements of all R410A VRF systems, including a standard heat pump and a fancier heat-recovery system, which simultaneously heats and cools. It performs excellently on any commercial assignment.

What is the rationale behind using copper as the VRF joint material?

Copper is the preferred material for VRF joints because it just works well in this application. It carries heat efficiently, doesn’t corrode easily, and is strong enough to handle the pressures the system runs at for years. It also brazes cleanly, which helps in getting a proper, tight connection on site. In the long run, it’s this combination that keeps the joints reliable for the full life of the VRF system.

What is so special about installing VRF systems with the CL series?

It reduces the on-site brazing of custom components. The kit is pre-prepared and accurate, and therefore you spend less time working, fewer errors, and complete the task in a shorter time. That saves money and provides the system with a better grip at the very beginning.

Where do I get technical specifications or a CAD drawing of the CL Series?

You can drag all the specifications, size drawings, and computer-aided designs directly out of 227 Enterprise. Simply call their technical support on the internet and request the specific data to be able to adjust it to your design schemes and pipe configurations.
