227 Enterprise – VRF Joints and Refrigerant Copper Fittings

pns Series

Engineered for Flawless Compatibility & Leak-Free Performance in R410A Systems 

The PNS Series Refrigerant Branch Piping Kit is the inside job that ensures the refrigerant separates itself in the large VRF/VRV systems. It is designed specifically to fit R410A, and it has both suction line and liquid line copper Y-joints that are cut precisely. And then we put on the correct size copper reducers to enable it all to hang together.

It is a generic Multi-Step design, thus it fits a variety of pipe sizes and the large OEM brands- no bizarre additional parts on site. All joints receive hard pressure tests of 5.2 MPa in order to ensure they are 100 per cent leak-free and long lasting.

What comes in a PNS Series VRF Branch Piping Kit?

You are supplied with a set including two accurate copper Y-joints, one to fit the liquid line, one to fit suction, and reducers of the proper size in copper. We also include a high-quality insulation pack (XLPE or Class O NBR ArmaFlex ) so that condensation does not creep on the cold pipes. This would imply a clean, smooth, and long-lasting installation of your VRF system.

Will your PNS Series kits work with my VRF brand?

Absolutely! Their universal Multi-step design ensures that they can be used without any problem with all the major OEM brands. This makes your inventory easy and provides you with solid performance across the lines of system specs- no compromises, just great fit.

What do you do to ensure that the joints are leak proof?

Each copper connection is pressure-tested all the way up to 5.2 Mpa (approximately 754 psi) at our facility. That is much more than the system is used to, and we can be confident that the system has been brazed and sealed like iron, one great guarantee that the connection will remain dry forever.

What are the quality certifications of your products?

Our final PNS Series products or production are in compliance with RoHS and CE. That is to say that we have the right environmental safety and material purity, and we adhere to the stringent international regulations of electrical and mechanical equipment.

Which insulation options do you make, why?

Proper insulation prevents condensation of pipes that are cold- important in saving energy and preventing water destruction. Our two best sellers are fire-resistant XLPE or Class O NBR, both of which are selected due to their excellent thermal resistance, as well as long-lasting performance in all climates.

Minimum order quantity (MOQ)?

We are adaptable on MOQ to facilitate small retrofit projects to large commercial projects. You just call our sales crew with your size and quantity of pipes and we will send you a unique quote and most optimal ordering plan.

Do you offer after sales services or warranties?

Yes, we do stand behind what we supply. If you need any help during installation or have questions about system integration, our technical team is available to guide you through it. For added peace of mind, every PNS Series kit comes with a 6-month warranty covering any manufacturing defects in the Y Joint.

Are you able to create kits not based on standard or proprietary pipes?

Definitely! We have good engineering capabilities in custom jobs. Branch piping solutions based on your drawings or samples can be designed to meet special specifications, special OEM layouts or complicated layouts that require non-standard, accurate splits of refrigerant flow.

Why is proper refrigerant piping so important in VRF systems?

Proper piping ensures that the refrigerant travels at the appropriate rate and oil returns to the compressor, which is necessary to be efficient, capacity, and compressor life. Good joints reduce pressure drops and prevent leaks, which reduce energy consumption directly, maintain system stability, and reduce overall life-cycle costs.

What is the order or quote procedure on the PNS Series?

Simply email us the order to sales at 227enterprise.com or call. Our team will assist you in choosing the appropriate model, provide you with competitive prices, and arrange a solid shipping to any location that you require it so that the entire process of buying is without any hassles.
