FILTER UNIT+BLOWER Ventilation System

Project Background

A leading global energy technology company required a complete intake and exhaust acoustic solution for a distributed energy project in Houston, Texas, USA.

The project was developed for a major North American energy company and involved a 5.1MW SGT-100 gas turbine system. The equipment required strict compliance with North American standards, including structural safety, acoustic performance, corrosion protection, and outdoor operating reliability.

CLET provided an integrated design and manufacturing solution for the complete gas turbine intake and exhaust system, including intake silencers, exhaust acoustic ducts, exhaust stack modules, structural supports, and maintenance platforms.

Project Name:
North American Oil & Gas Power Project
Delivery Type:
Integrated Design & Manufacturing Delivery
Delivered Products:

  • Gas Turbine Air Intake System

  • Maintenance Platforms & Access Ladders

Project Challenges

Strict North American Outdoor Requirements
The Houston project environment involves:

  • High temperatures
  • Dust and sand exposure
  • Outdoor operation
  • Potential salt contamination

The complete intake and exhaust system needed to meet North American requirements for:

  • Corrosion resistance
  • Dust protection
  • Weather durability
  • Long-term outdoor reliability

Complex Structural & Acoustic Integration
The SGT-100 intake and exhaust system required elevated installation with large-span structures.
The design needed to consider:

  • Structural load capacity
  • Wind load resistance
  • Seismic performance
  • Acoustic attenuation
  • Overall system stability

Improper modular design could result in structural vibration, resonance, and reduced noise reduction performance.

High Cost of Local Construction & Installation
North American construction costs are significantly higher than many other regions.
The customer required maximum factory prefabrication to reduce:

  • On-site welding
  • High-altitude installation work
  • Acoustic lining installation
  • Construction time

Need for Reliable Export Manufacturing Capability
The project required a supplier capable of providing:

  • 3D engineering design
  • Structural calculations
  • Acoustic analysis
  • Factory prefabrication
  • International export delivery

  • Corrosion coating
  • Platform and ladder assembly

The equipment was designed into transport-friendly modules suitable for container shipping.
After arrival in Houston, only:

  • Flange connection
  • Structural assembly
  • Final installation

were required, significantly reducing overseas construction workload.

4. Complete Technical Documentation & Project Compliance
CLET provided comprehensive project documentation, including:

  • 3D engineering models
  • Structural load calculation reports
  • Acoustic testing reports
  • Corrosion protection specifications

All documents complied with international project requirements and successfully passed technical reviews and factory inspections.
