Our Advantages

The main features and benefits of NCC acoustic louvers are:

Equipped with weatherproof sealing plate to prevent rain and snow infiltration.Equipped with rainproof and rust-proof material selection and
surface treatment process.

Reduce reflection noise and parallel barriers to improve indoor sound insulation.
Louver ventilation improves indoor air quality.The modular design makes the louvers suitable for "vents" of any size.
It can be used as an independent barrier around the equipment or combined with building walls.Composed of prefabricated parts, it can be assembled in the field quickly and without welding.

The horizontal layout of the sand shutter not only reflects the beauty, but also enhances the sand and dust prevention performance.Effectively prevent sand and dust from entering the room and adjust the indoor temperature and humidity.

With steel structure design ability, with wind, snow load calculation ability, improve indoor safety.Meet anti-theft requirements and standards.

NCC's louvers have an energy-efficient aerodynamic design and very low pressure drop characteristics. The robust all-metal construction ensures the long service life of the NCC noise reduction louvers. If required, we can also supply the necessary supporting steel structures and provide comprehensive installation services.And for each individual project, it can be adjusted according to site conditions, as well as environmental factors.

The specification shown in Table 2 matches very closely desert type sand and dust, and illustrates an overall grade. Other grades of sand can also be used for the tests and are specified as follows:

a) FINE - sand between 106 and 150 um.              b) COARSE - sand between 355 and 425 um.

Laboratory testing

 NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers

         We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities.   For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures.   Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.

 

The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures.   Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
    As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower.   The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
