Application
Transformer/substation sound insulation room:
Ensure good ventilation to remove peculiar smells, moisture and harmful gases. At the same time, it is necessary to prevent rainwater, sandstorms, etc. from entering, which could corrode the internal equipment and goods.
Radiator, boiler room:
The louvers should have good ventilation performance and be able to quickly and effectively discharge the hot air outdoors.
Ventilation louvers for radiators in construction machinery:
It should be able to adapt to the vibrations during the operation of the machinery and the harsh working environment, and possess strong sturdiness and impact resistance.
Air intake air intake in the data center:
The intake louvers should ensure the entry of fresh air and, at the same time, prevent rainwater and moisture from flowing back into the pump room.
Exceptional Protection Performance:
The carefully equipped weatherproof sealing plate can extremely effectively block the infiltration of rain and snow, ensuring that the internal space is not affected by harsh weather conditions.
Superior Acoustic Effect:
The unique design can significantly reduce reflected noise. By optimizing the structure of the parallel sound barriers, the sound insulation level of the indoor space is greatly improved, creating a quiet and comfortable environment for users.
Excellent Air Conditioning Function:
The reasonable ventilation design of the louvers can efficiently improve the indoor air quality, promote air circulation, and keep the indoor air fresh at all times.
Flexible and Diverse Installation Methods:
The product is composed of prefabricated components, which is extremely convenient and rapid for on-site assembly. There is no need for complex welding procedures, greatly saving installation time and labor costs.

The single row shutters FYL100S series feature a good airflow rate and are rated at airflow grade 2.
The double row shutters FYL155S series are rated A for high rainwater permeability, and their airflow rate and airflow class are both rated as 2.
All NCC rain blinds have test reports compliant with Chinese GB standards. For each project, calculations of the free area can be provided according to the size of the shutter segments.
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.
