Air Compressor Energy-saving Renovation Starts with Energy Audit
In manufacturing enterprises, the compressed air system is usually the second largest energy consumer after electric power. Nevertheless, most enterprises lack a clear understanding of their air compressor energy efficiency, resulting in massive invisible energy waste.
Deman owns a professional engineering team specializing in compressed air energy audit and energy-saving renovation. With years of technical experience in pneumatic systems and in-depth insight into production equipment and processes across various industries, we provide systematic energy audit services to accurately tap energy-saving potential for factories.
- Central Control Room Audit
The central control room is the command center of the compressed air station, providing first-hand operating data.
- Confirm whether a centralized control system is equipped; take photos and record real-time operating data
- Identify defects and bottlenecks of the original system
- Collect layout drawings of the compressor room and air pipeline network
- Communicate with maintenance staff about unit scheduling, operating hours and daily usage habits
- Compressor Room On-site Audit
The compressor room is the core inspection area, with detailed testing conducted on every single device.
- Data Collection
- Nameplate information: power, model, factory technical parameters
- Running time and loading time
- Discharge pressure and temperature
- Upper and lower pressure set points
- Parameters of post-treatment equipment and piping layout
- Real-time Monitoring & Testing
Professional instruments are used for on-site measurement and recording:
- Operating power, discharge flow, pressure and temperature of each compressor
- Main air pipeline flow, pressure, temperature and dew point
- Locate air leakage points with leakage detection guns and keep photo records
- Test overall pipeline leakage volume with professional detectors
- Pipeline Sorting
In reference to factory-provided layout drawings:
- Clarify the routing of compressed air pipelines
- Sort out cooling water pipeline arrangement
- Demand & Renovation Intention Communication
Through technical communication:
- Investigate existing pain points in system operation and daily management
- Learn about the enterprise’s renovation intention, budget and expected energy-saving goals
- Air Pipeline Network Audit: Minimize Transmission Loss
Compressed air transmission loss is often overlooked during delivery from the compressor room to workshops.
- Review original air supply pipeline drawings
- Map the complete transmission network covering all production workshops
- Identify unreasonable design of pipes, valves and air receivers with photo documentation
- Deliver targeted optimization suggestions
Common problems:
undersized pipe diameter, excessive elbows, improper valve selection, unreasonable air receiver placement, etc.
- Terminal Equipment Audit: Full Coverage from Source to End-user
Terminal air-consuming equipment determines actual air demand and directly affects overall system energy efficiency.
1.Data Statistics
- Type and quantity of terminal air-using equipment
- Actual required pressure, flow and dew point of each workshop
- Rated parameters of production equipment
2. Sampling Inspection
Collect and record on-site data via meters and testing tools:
- Operating data of main supply pipelines in each workshop
- Branch pipeline operating conditions
- Flow, pressure and dew point of key terminal equipment
3. Core Value of Professional Energy Audit
Through comprehensive compressed air system inspection, Deman delivers:
- Accurate Positioning: Pinpoint root causes of high energy consumption
- Quantified Potential: Scientifically evaluate energy-saving rate and economic benefits
- Customized Solutions: Offer practical, tailored renovation plans
- Continuous Optimization: Provide data support for construction, operation and effect verification
When it comes to air compressor energy-saving renovation, the first step is not equipment replacement, but professional energy audit.
Deman’s energy-saving team delivers one-stop services from on-site audit to overall renovation, supported by professional technology, standardized processes and accurate data.
