Product Description

 

Product Description

NCC, as a globally leading manufacturer of human settlement equipment, has meticulously engineered its sand-proof louvers to integrate functionality and durability. These louvers not only utilize high-strength materials to ensure robust and long-lasting performance but also incorporate a unique design that effectively blocks sand and dust intrusion while maintaining unobstructed air circulation between indoor and outdoor environments. By achieving this balance, they create a clean, comfortable, and well-ventilated space suitable for a wide range of applications, from industrial facilities to residential and commercial settings.

Application

Ventilation System Air Intakes:
Installed at the air intake end of ventilation systems, they block the intrusion of sand and dust particles through precision filters and blade structures, maintaining air circulation while preventing sand from entering downstream equipment.
Outdoor Equipment Air Intakes:
Providing protection for outdoor equipment in sandy environments such as deserts and gobi regions, they prevent sand accumulation from blocking heat dissipation channels and ensure continuous stable operation of the equipment.
Equipment Room and Machine Room Air Intakes:
Designed for the ventilation needs of industrial equipment rooms, they use high-strength blades and filtration systems to block sand entry, maintaining equipment heat dissipation efficiency and reducing wear on precision components caused by sand.
Substation and Transformer Soundproof Room Air Intakes:
Applied in substation ventilation scenarios, they use sand-proof design to prevent sand from entering electrical equipment areas, balancing heat dissipation and soundproofing functions while reducing sand erosion on high-voltage equipment.
Building Ventilation Systems in Arid Desert Regions:
Suitable for ventilation openings in residential and industrial buildings in sandy climates, they use removable filters and sand-proof blade structures to isolate sand while introducing fresh air, creating a clean indoor environment.
Industrial Equipment Control Cabinets and Dashboards:
Providing protection for the air intakes of various industrial control cabinets, they prevent sand from entering the cabinet interior with airflow, avoiding dust accumulation that could affect circuit or mechanical component operation.

 

Our Advantages

High-Efficiency Sand Protection:
Utilizing precision filtration and aerodynamic blade design, it effectively blocks sand intrusion while maintaining stable air circulation, preventing equipment failure caused by sand accumulation.
All-Weather Durability:
Constructed from high-strength, corrosion-resistant materials, it adapts to extreme environments like desert heat and coastal high salinity, resisting wind-sand abrasion and chemical erosion to extend service life.
Easy Maintenance Design:
Integrated filter and louver system with a detachable structure enables quick cleaning, reducing manual maintenance costs.
Modular Flexibility:
Offers various specifications, installation methods, and filtration grades to adapt to the personalized needs of different equipment cabinets and building ventilation systems.
Multi-Scenario Professional Protection:
Provides customized solutions for industrial equipment, building ventilation, and outdoor facilities, addressing heat dissipation protection and air cleanliness issues in sandy environments.
High Reliability and Cost-Effectiveness:
Structure designed to withstand strong wind and sand impacts ensures long-term stable operation in unattended scenarios, lowering life-cycle maintenance costs.

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.
