Testimonial's
The way 227 Enterprise tracks it all and guarantees that there is no leakage whatsoever is a reason why we did not need to spend time testing it on site, and we have confidence in the system.
Head of Procurement, MEP Consultancy,
Saudi ArabiaTheir GR Series is compatible with any brand, thus managing the project was very easy, and the technological support was big time phenomenal.
Luxury Hospitality developer, project director,
UAEWe have been working with 227 Enterprise in all our VRF projects since the parts are always presentable, and the insulation prevents any sweating.
Mechanical Contractor,
Japan, Senior Engineer.They have perfect Y-joints which are machined and rounded edges, hence very fast to install, which reduces a lot of labor expenses.

Why are the GR Series any different from regular copper Y-joints?
They are not mere loose components; these are ready-assembled, ready-insulated, 2 percent silver-brazed joint, kits. All kits receive a leak test in the factory, and thus, the installation is fast and the VRF system performs optimally. It eliminates the guesswork of field brazing and provides you with solid, dependable performance that is difficult to match using ordinary kits.
Do GR Series kits work with all major VRF/VRF brands?
Yep. It is designed to fit all the major contenders that use R410A. It translates into fewer headaches in the process of purchasing a project that requires a combination of brands, since you will not be required to go on a hunt in search of brand-specific components. The GR kit will fit in perfectly.
What do you do to make the joints 100 per cent leak-proof?
All the joints are subjected to a 2% silver alloy, followed by a helium leak-test of 5.2MPa pressure. That two-fold check assures you of the permanence and hermetically sealed nature of the seal, which is much better than the conventional pressure tests, so you can be sure of it under all the high-pressure cycles of R410A refrigerant.
What are the certifications of your GR Series products?
The kits are safe and environmentally friendly as they comply with the ROHS and CE standards. We have our own internal quality assurance and can provide you with complete material certifications and test reports whenever you require them for your project files, audit or QA reviews.
Are you able to offer custom-configured kits to non-standard projects?
Absolutely. We know how to customize branch piping kits to fit special layouts, odd port configurations or additional insulation requirements. Only send us your specs, and we will make you a perfect-fit kit, with no compromise in quality or leaks.
How long are the lead times on orders?
GR kits of standard are available in stock and can be shipped quickly. In the case of custom builds, we provide a definite production schedule when you place the order. We deliver on time to ensure that your project is on schedule.
What are the insulation alternatives?
Our insulation is of the highest grade UV-stabilized XPLE or Armaflex Class O NBR. That material prevents the loss of energy, prevents any form of sweating or condensation, and keeps the interior of the building dry and free of mould. It is also fire-rated, and hence it assists in safety compliance of commercial and residential installations.
Do you offer technical installation services?
For sure. Our HVAC professionals will distribute user-friendly manuals and discuss with you the most suitable piping designs. They are even willing to assist you in installing the GR kit in a manner that the entire VRF system will be running smoothly and reliably.
What is the benefit of this to the VRF system efficiency?
The kits ensure that refrigerant flows uniformly with little pressure drop and turbulence. That allows each of the indoor units to receive the precise flow they require, maintaining the entire system at the highest level of SEER/COP performance and reducing the energy consumption and operating expenses.
What is your after-sales policy?
We support it with a good warranty and powerful after-sales service. Our monitoring system identifies any problems in a short period of time, and our team is on top of it to ensure that your system is performing excellently over the long term.
