Why 227 Enterprise

227 Enterprise is at the level of precision engineering and on-the-job HVAC performance. We do not sell off-the-shelf components as a Custom VRF Header manufacturer and VRF Customize Header Supplier, instead, project refrigerant solutions are designed to meet project requirements in relation to both OEMs need and site-specific conditions as well as long-term objectives. Our headers are designed to suit consultants, EPCs, and businesses that desire predictability, compliance, and consistency of system performance.

And why would a vendor of a Custom VRF Header make his product interoperable with other OEMs?

A real manufacturer of Custom VRF Headers can have true universal compatibility with a multi-step design that can support a wide range of pipe sizes with the same fitting. We go an extra mile by providing the full customization of port numbers (2-8) and the accuracy of internal diameters of 6.5mm to 38.3m at 227 Enterprise. This guarantees that our headers are compatible with the piping specifications of any major brand to choose, such that via only one inventory part we can fit into any other significant system.

Why is 227 Enterprise brazed with 5% silver rods as opposed to lower or higher Silver content?

We have determined 5% silver-phosphorous-copper brazing alloys to be the best in terms of performance, reliability and value in VRF headers. This level of silver content gives much greater ductility and gap-filling properties over 0% rods to form Joints that resist crack propagation through vibration and thermal loads. Although 15 percent silver is easier to handle, the 5 percent alloy is adequate enough to create leak-proof integrity during copper-to-copper brazing with a high level of accuracy, which requires no extra cost to attain because the brazing process guarantees precision and factory-controlled uniformity, yet the cost is comparatively lower than we can dictate a superior, reliable product at a favorable price point.

How does your customised header's pressure rating and how do you verify it?

All of our customized headers undergo intensive pressure testing up to 5.2 Megapascals (MPa) of pressure before the departure of our plant. This test pressure is by far much higher than the actual operating pressure of both R410A and next-generation refrigerant systems, and thus the test pressure has a high safety margin. This 100 per cent testing procedure, along with our use of heavy-duty copper tube, with its solid, heavy walls, will ensure that every item shall run in an unblemished seal under actual installation conditions, which will guarantee safety, efficiency and durability of the system throughout the existence of the installation.

How customized will a VRF Customize Header Supplier be?

We pride ourselves on being a highly collaborative engineering partner rather than just a parts supplier. Our core service is built around adapting to your specific project requirements, whether for a complex retrofit, a space-constrained installation, or a prototype system. We work directly with you from concept to completion, offering genuine design flexibility to create the exact component your project demands.

What is the role of the insulation of customized headers in system efficiency in general?

Correct insulation is necessary to avoid the problem of condensing energy and ensure accurate refrigerant temperature. We offer these custom-fitted insulation jackets of such materials as fire-retardant XLPE or closed-cell NBR elastomeric foam that is carefully cut to conform to the unique shape of your header. This closes thermal insulation holes and provides the full thermal coverage, which has the direct ramifications of guaranteeing the rated SEER and COP efficiency of the system, through limiting thermal losses/gains at the points of distribution, thus safeguarding your investment in the high-efficiency VRF technology.

What are the lead-times of a custom-designed header and what are the inputs you require to begin with?

Customized header lead times depend on the complexity, although our specific manufacturing processes smooth lead times. To give a correct quote and start engineering, we need the information: the number of ports, inlet and outlet pipe IDs (in mm), desired wall thickness, length of the product, type of refrigerant and desired insulation material. A schematic or system diagram is provided to make the process faster. We value effective communication so that the finished product will be of exactly the specifications and project-time calculated.

Do you have international quality and safety products?

Yes. We have manufacturing processes and products of high international standards. All our copper components are produced out of certified C12200. Brazing and pressure testing (5.2 MPa) are carried out using our methods which give even higher integrity of the joints than industry requirements. Also, our insulation, including our FR-Grade XLPE and our ASTM E84-rated NBR, is of utmost fire safety and smoke development requirements to be installed in business and residential structures.

As the VRF market expands at a very high rate, how does 227 Enterprise keep its components up to date?

We plan the future of HVAC. Our headers are designed with the capability to be compatible with the existing R410A systems as well as successive generations of refrigerants with lower Global Warming Potential (GWP) such as R32. This is in the choice of the materials, excellent design due to potentially increasing operating pressures, and consideration of trends in the industry. Being your customize Header VRF Systems Manufacturer, you ensure a partner whose components provide us with potential interests on the long-term feasibility and functionality of your facilities.

What is your minimum order quantity (MOQ) of customized header?

We can learn that projects range from a one-unit retrofit to a large new building. Thus, we provide laxing MOQs to cater to the needs of all our clients. We will become a solutions partner, either a one-off design creation to solve a unique problem or a large volume production to create a large development. Get in touch with us directly so that we may listen to your scope and volume requirements in a particular project.

Are you capable of supplying complete refrigerant branch piping/kits, as well as individual headers?

Absolutely. We are a wholesome manufacturer and provide entire branch piping solutions for refrigerants. This may involve our tailor-made headers, copper Y-joints perfectly fitting, straight copper tubing of ACR, requisite reducers, and custom insulation of all items.
