FSE conducted a comprehensive performance assessment of a multistage turbo air compressor after identifying reduced airflow and elevated specific power consumption.
The project combined on-site measurements, impeller and air cooler cleaning, internal inspection, tip-clearance adjustment, and post-service engineering analysis.
Project Name
Energy Audit and Efficiency Restoration for Multistage Turbo Air Compressors
Category
Energy Audit
Client
Abico Dairy Farm Co., Ltd.
Equipment
Multistage turbo air compressor
Compressor Model
T2A-125-M
Discharge Pressure
0.7000 MPaG
Location
Pak Chong, Nakhon Ratchasima, Thailand
PROJECT OVERVIEW
THE PROJECT FOCUSED ON RECOVERING COMPRESSOR AIRFLOW, IMPROVING ENERGY EFFICIENCY, AND REDUCING LONG-TERM OPERATING COSTS.
Before the service, the compressor continued to maintain the required discharge pressure but delivered only 711.20 m³/h of airflow at a specific power consumption of 0.1540 kW/(m³/h).
The measured data indicated reduced aerodynamic performance and showed that the system required more energy to produce each unit of compressed air.
PROJECT PROCESS
FSE MEASURED THE EXISTING PERFORMANCE, CLEANED, INSPECTED AND ADJUSTED THE AERO PART, THEN VERIFIED THE IMPROVEMENT THROUGH POST-SERVICE TESTING.
Baseline operating data was collected before service, including airflow, pressure, electrical current, voltage, shaft power, temperature, and specific power consumption.
The impeller and air cooler were cleaned, while internal conditions and tip clearance were inspected and adjusted. A performance test was then conducted again after service to measure the recovered compressor performance.
KEY RESULTS
SUMMARY
THE COMPLETED SERVICE RECOVERED COMPRESSOR PERFORMANCE AND DELIVERED MEASURABLE OPERATIONAL, FINANCIAL, AND ENVIRONMENTAL BENEFITS.
After cleaning and inspection, airflow capacity increased from 711.20 m³/h to 1,032.84 m³/h while the discharge pressure remained stable at 0.7000 MPaG. Specific power consumption decreased from 0.1540 to 0.1209 kW/(m³/h), demonstrating that the compressor could deliver significantly more compressed air with improved energy efficiency.
This reduction in energy intensity also lowered the carbon impact of compressed-air production. Specific CO₂e generation decreased from 0.0827 to 0.0649 kg CO₂e/m³, representing an estimated annual emissions reduction of approximately 139.73 tCO₂e.

The completed service improved the compressor’s operational, financial, and environmental performance. Airflow capacity increased by approximately 45.2%, while specific power consumption decreased by approximately 21.5%.
This efficiency improvement is estimated to save approximately 273,292 kWh of electricity and ฿1.09 million in operating costs annually. By reducing the energy required to produce each unit of compressed air, the project also lowered specific CO₂ generation from 0.0827 to 0.0649 kg CO₂e/m³, representing an estimated annual carbon-emission reduction of 139.73 tCO₂e.
