What is NBR insulation, and why do we need this in VRF systems?

NBR, Nitrile Butadiene Rubber, is a closed-cell foam specifically designed to fit the HVAC pipes. It excludes heat, prevents condensation and is fire-proof. It fits into tricky Y-shaped joints since it is super flexible, and it ensures that the system will operate in the same manner and meet international standards.

What are the major characteristics of NBR Insulation?

Any joint can be easily fitted on--needless of any tools. It has Microban to prevent mould, it satisfies ASTM E84 -25/50 in Class O fire safety, and it has RoHS/CE on the list. It has super-low conductivity and therefore reduces the energy level, hence it is durable, safe, and high quality in tough applications of VRF.

Is NBR fireproofed, and what are the standards of NBR?

Well, it is fireproof, it is basically. We subject it to serious tests, and it was rated ASTM E84 -25/50 -Class O at the top of the categories. That prevents fire from spreading and smog buildup, which provides life-saving personnel with a chance of escape and achieves challenging building standards all over the world.

What is the advantage of the Microban antimicrobial protection to the system?

Microban prevents the sprouting of mould, germs, and bacteria in the foam. It implies cleaner indoor air, prevents the insulation from wearing out, and makes the building feel healthier, which is extremely crucial in both office and home VRF systems.

What are the global market certifications of NBR Insulation?

It has all the major certifications, ASTM E84 fire, RoHS no harmful materials, and CE European safety requirements. Those demonstrate that it has the capability of doing tough work in any place with a tight standard, especially.

What is the energy efficiency in use of NBR insulation in VRF systems?

Its super-low heat conduct prevents the leakage of hot or cold through the lines. That maintains the refrigerant in the optimal temperature, reduces the load of the compressor and reduces the overall energy consumption. It saves a great deal of money in the long run and makes the entire building run in an easier way.

Is this insulation available for indoor and outdoor uses

Yes, it features a closed-cell design that supports water and UV rays, making it suitable for use outside as well. If it is exposed to the sun throughout the day, we recommend using a UV shield coat. Its germ-blocking and fire-proofing features would provide a little more protection in the house and make the air safer.

What is the custom-fitting of the insulation to the various VRF Y- joints?

Each bit is laser cut and CNC technology suited to fit precisely the shape of each Y-joint. That will have a snug, seamless fit which is easy to wear and prevents heat and moisture to escape.

What is the projected service life of NBR Insulation?

When it is installed correctly and as long as it is not exposed to damage it can last 15-20 years. The closed-cell foam prevents ageing, soaks up water and germs, and therefore, it remains efficient in reducing the temperature and durable.

Why would NBR Insulation pick 227 Enterprise among the other suppliers?

227 Enterprise combines the finest AP ArmaFlex foam with CNC fitting to make the components fit precisely. We launched it certified in fire safety, germ protection and actual performance in Europe. We also provide good tech support, consistent supply, and quality guarantee to make sure your VRF project is finished out of this world.
