Product Description

 

Product Description

 

 

NCC is a leading manufacturer of noise cancelling louvers worldwide, with sturdy, durable, and high-performance products that have been applied multiple times worldwide. The application scenarios of NCC noise cancelling louvers include:

Air inlet of ventilation system                Air inlet of outdoor units such as cooling towers

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 joint locks, latches, and handles

Soundproof doors can be provided with bird guards and insect nets upon request

The door can be provided with polyester powder coating

Can be made of galvanized steel, stainless steel, or aluminum
 



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.

 

Product Range

 

•Need to eliminate noise and provide ventilation

•Building ventilation

•Generator room ventilation

•Sound insulation walls and fences

•Sound insulation hood ventilation

•Industrial and building ventilation systems

•Silencing louvers are used as part of a building, structure or equipment intake/exhaust system to help reduce noise generated by system equipment. They have a relatively large surface area to compensate for their lack of depth.

Sound barrier/enclosure application scenarios

High performance sound barriers provide effective solutions for reducing environmental noise pollution. Our certified sound barrier can solve various environmental noise problems, including transportation, public utilities, machinery factories, sports facilities, industrial sites, urban light rail and high-speed rail, bridges, logistics centers, mechanical equipment such as water pumps, compressors, cooling towers, transformers, converters, etc.
 

Product advantages

•Reliable sound insulation performance: Products tested in the laboratory have guaranteed sound insulation/absorption performance (non theoretical calculation)

•Reduce sound energy: The absorbing surface minimizes reflected noise and reduces parallel barriers•Corrosion prevention: Equipped with rainproof and rust proof material selection and surface treatment process

•Modular plugin: The surface is flat and can be treated with a wide range of options, resulting in landscape integration

•Structural design: Possess the ability to design steel structures, capable of calculating wind and snow loads

•Rapid organization: composed of prefabricated components, capable of rapid, non welded on-site assembly

For each individual project, it is possible to select a panel design which has the required sound transmission loss and sound absorption ratings.

Construction specifications of sound insulation room:

•High sound insulation doors and windows
•Unidirectional mirror, which can be viewed from the outside in, but cannot be viewed from the inside out
•Install hidden microphones and other digital devices
•Silent ventilation to reduce pressure levels
•Lay carpets on the ground to create a warm atmosphere and enhance indoor voice clarity
•Impact resistant Varitone ™ Metal sound-absorbing panels can resist impact and ensure speech clarity and recording qualityFault prevention devices can be built into walls, ventilation systems, and input/output signals

We are also able to offer a full range of engineered solutions to industrial noise, all centredaround modular components that can work independently or as part of a package to solve even the most complicated of projects.
