Noise Challenges in Industrial Equipment
Fans, heat pumps, air compressors, and high-performance servers generate mid- to high-frequency mechanical and airflow noise during operation. These noise levels can disrupt work environments and may exceed local or international environmental regulations. Conventional insulation materials are often too heavy, lack flame resistance, or have a limited temperature range, making them unsuitable for continuous high-temperature industrial applications.

YDNFOAM™ Solutions
Acoustic Liner Pads
Applications: Fans, heat pumps, air compressors, servers
Key Advantages:
oUltra-lightweight: Density of only 4 kg/m³ melamine foam, minimizing structural load
oHigh Sound Absorption: NRC ≈ 0.85 (mid–high frequency) for effective noise reduction
oFlame-Retardant: UL94 V-0 self-extinguishing performance meets stringent electrical and server-room fire codes
oWide Temperature Range: Stable from -200 °C to +240 °C, with no crumbling or shrinkage
Installation: Available in rolls or custom-shaped parts for direct bonding or insertion into equipment housings, ensuring fast retrofit and maintenance.
Ventilation Duct Acoustic Liners
Applications: Industrial plants, server rooms, data centers, cleanrooms
Key Advantages:
oOpen-cell microstructure significantly reduces airflow noise and resonance
oMoisture-resistant and antimicrobial, preventing cracking and mold growth for long-term HVAC performance
oFlexible installation, easy to cut or bend for complex duct geometries

Typical Industries & Detailed Applications
1. Data Centers & Cloud Computing Facilities
Noise Challenge: Continuous high-frequency noise from cabinet fans and cooling systems affects maintenance staff and operational comfort.
Solution: YDNFOAM™ liners installed in cabinet sidewalls, airflow channels, and cooling ducts reduce noise by 10–15 dB(A) while meeting UL94 V-0 and EN45545 fire-safety standards.
2. Industrial Parks & Large HVAC Systems
Noise Challenge: Central air-conditioning units, cooling towers, and AHUs create a combination of low-frequency vibration and high-frequency fan noise.
Solution: 4 kg/m³ melamine foam liners inside fan housings and supply/return ducts deliver long-life, low-maintenance acoustic control.
3. Smart Manufacturing & Automated Production Lines
Noise Challenge: Stamping machines, air compressors, and industrial robots generate persistent mid-high-frequency mechanical noise.
Solution: Custom-shaped YDNFOAM™ acoustic pads or inner linings for equipment enclosures lower workplace noise and help plants comply with industrial noise emission standards.
4. Medical & Biological Laboratories
Noise Challenge: Operating rooms, labs, and cleanrooms require quiet airflow with minimal particulate release.
Solution: Non-dusting, low-VOC YDNFOAM™ panels serve as duct liners and diffuser inserts, providing silence and maintaining clean-air integrity.
5. Energy & Power Facilities
Noise Challenge: Gas turbines, wind turbines, and energy-storage systems operate continuously under high temperatures and demand top-tier fire safety.
Solution: YDNFOAM™ is ideal for generator rooms, battery containers, and substation ducts, combining high sound absorption with thermal insulation.

Key Benefits
Noise Reduction: Proven to lower noise levels by 10–15 dB(A) or more
Extended Equipment Life: Damps vibration and resonance, protecting motors and key components
Regulatory Compliance: Helps facilities meet industrial noise and fire-safety standards worldwide
