Machine room air inlet                            Data center vents

Water pump room air inlet                 

Transformer/substation sound insulation room heat sink boiler room

Ventilation louvers for construction machinery radiators

Ventilation openings on soundproof enclosures

Wind turbine vent                                    


Dimension & Appearance

 

NCC louvers can be made into sound-absorbing louvers with single or double leaf structures, with a minimum structural height of 850mm. The standard height for single leaf doors is 1250mm x 3000mm, and the height for double leaf doors is 2500mm x 3000mm

All doors are equipped with connecting locks, latches and handles (samples available or customized upon request)

The sound insulation door can be equipped with bird and insect screens as required

Doors can be coated with polyester powder coating

It can be galvanized steel, stainless steel, or aluminum
 

Our Advantages

The main characteristics and advantages of NCC acoustic louvers are:
Equipped with weather resistant sealing plates to prevent the infiltration of rain and snow
The modular design can make the louvers suitable for use with any size of "vent"

It can serve as an independent barrier around equipment or be integrated with building walls

The blades of the silencing louver are arranged horizontally, reflecting aesthetics and enhancing acoustic performance

It can be equipped with stainless steel or galvanized bird nets, as well as insect nets

Meet anti-theft requirements and standards

NCC's anechoic louver has an energy-efficient aerodynamic design and a very low pressure drop characteristic. The sturdy all metal structure ensures a long service life for NCC's noise reduction louvers. If necessary, we can also provide necessary supporting steel structures and provide comprehensive installation services.

Testing Report

         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.
