A leading Japanese energy equipment integrator specializes in gas turbine power plant solutions, including heavy-duty gas turbine equipment, air filtration systems, and acoustic noise reduction solutions for domestic and international power projects.
With strict requirements for manufacturing precision, acoustic performance, and engineering quality, the customer required a reliable partner capable of delivering a complete gas turbine acoustic system solution.
CLET provided a full set of prefabricated acoustic equipment for the 32MW H25 gas turbine, including air intake filtration house, turbine acoustic enclosure, and ventilation noise reduction systems, delivering a complete integrated solution from design to manufacturing.
Japan
Gas Turbine Model:
32MW H25 Heavy-Duty Gas Turbine
Delivered Products:
Gas Turbine Air Intake Filtration House
Gas Turbine Acoustic Enclosure
Ventilation & Noise Reduction System
Delivery Type:
One-stop prefabricated system delivery based on customer engineering requirements.
Strict Environmental & Acoustic Requirements
The Japanese market has high standards for environmental protection, requiring strict control of equipment noise, vibration, and dust emissions. The complete system needed to meet multiple requirements including noise reduction, dust prevention, and vibration control.
Complex System Integration
Due to the large scale of the 32MW H25 gas turbine system, the air intake, acoustic enclosure, and ventilation modules require highly coordinated design. Separate procurement from multiple suppliers could result in interface mismatches and extended commissioning periods.
High Manufacturing Quality Standards
The project required strict control of welding quality, surface finishing, corrosion protection, sealing performance, and overall appearance. Conventional manufacturing processes could not fully meet the customer’s high-quality expectations.
Need for Integrated Supply Capability
Previously, filtration systems, acoustic enclosures, and silencers were supplied by different manufacturers, increasing coordination complexity. The customer required a reliable supplier capable of providing complete acoustic system solutions.
1. Integrated Acoustic System Delivery
CLET provided a complete gas turbine acoustic solution with unified design, manufacturing, and quality control, covering three key systems:
Gas Turbine Air Intake Filtration House
Gas Turbine Acoustic Enclosure
Ventilation & Noise Reduction System
All components were manufactured with unified dimensional standards and assembly references, ensuring accurate installation without on-site modification.
2. High-Precision Manufacturing for Japanese Standards
To meet strict Japanese quality requirements, CLET optimized the complete manufacturing process:
The final products achieved both high-performance requirements and excellent appearance quality.
3. Factory Prefabrication & Modular Delivery
All major systems were pre-assembled at CLET’s facility, including:
The modular design was optimized for container shipping. After delivery to Japan, only final module connection and pipeline integration were required, significantly reducing on-site construction workload.
4. Long-Term Technical Partnership
CLET developed a standardized solution platform for the H25 gas turbine series and provided dedicated technical support throughout the project lifecycle.
Services included:
The cooperation established a stable long-term supply relationship for future gas turbine acoustic system projects.
Simplified Supply Chain Management
One integrated supplier provided air filtration, acoustic enclosure, and ventilation noise reduction systems, reducing coordination and project management complexity.
Successful Completion Under Strict Quality Requirements
The complete system met requirements for noise reduction, dust protection, corrosion resistance, and manufacturing quality, ensuring reliable operation in Japanese power plant environments.
Reduced Overseas Installation Costs
Factory-prefabricated delivery minimized on-site assembly work, reducing labor requirements and installation time.
Established Long-Term Cooperation
CLET became a trusted supplier of complete acoustic systems for H25 gas turbine applications, supporting future domestic and international power projects.
Showcasing our engineering expertise and successful project experience across aerospace, energy, and industrial sectors.
