IE C001SCREW COMPRESSOR TREATMENT REPORT, 2019
Bell Air AED 22A compressor: electricity savings without disassembly or repair
Drive motor current dropped on all three phases, no-load pressure increased. 15–21.4 % — drive motor current on all three phases under load, 40.84–43.9 → 34.5–34.7 A; 1.4 bar — working pressure at idle, 4.9 → 6.3 bar (2019).

Key result
| EQUIPMENT | CONDITION AT START OF TESTING | WHAT WAS MEASURED |
|---|---|---|
| Bell Air AED 22A screw air compressor, 22 kW drive | In service since 2013: elevated oil temperature, noise and vibration, longer air charging time due to worn parts | Current on all three phases of the drive motor and working pressure — under load and at idle |
Current of the 22 kW drive electric motor
| MODE AND PHASE | BEFORE TREATMENT | AFTER 50 H OF OPERATION | CHANGE |
|---|---|---|---|
| Under load, phase I | 43.9 A | 34.5 A | −21.4 % |
| Under load, phase II | 40.84 A | 34.7 A | −15.0 % |
| Under load, phase III | 41.3 A | 34.5 A | −16.5 % |
| Idle, phase I | 19.8 A | 18.2 A | −8.1 % |
| Idle, phase II | 20.3 A | 18.6 A | −8.4 % |
| Idle, phase III | 20.9 A | 17.7 A | −15.3 % |
The current drop was recorded on all three phases in both modes; the results section of the report states an average reduction in power consumption of 21.4 %.
Working pressure in the system
| MODE | BEFORE TREATMENT | AFTER 50 H OF OPERATION | RATED |
|---|---|---|---|
| Idle | 4.9 bar | 6.3 bar | 7 bar |
| Under load | 6.9 bar | 6.9 bar | 7 bar |
Under load the compressor held pressure close to the rated 0.7 MPa even before treatment — there was no room to rise; the gain of 1.4 bar came in the idle mode.

About this result:
Limits of this report: The results refer to the Bell Air AED 22A screw air compressor with a 22 kW drive and were obtained after 50 h of operation following treatment; on other units and under different operating conditions the figures may differ. The treatment was performed and the report prepared by PT XADO Indonesia.
