ECOAIR D40 compressor: restored while running instead of teardown repair
The compressor stopped overheating, thermal-protection trips ceased, discharge sped up. 10 % — compressor output, charge-up to 6.5–8 atm, 55 → 50 s; 25 % — oil temperature in the system, 80 → 60 °C (2009).

Key results
| EQUIPMENT | IN SERVICE SINCE | WHAT WAS MEASURED |
|---|---|---|
| ECOAIR D40 rotary screw air compressor | 1994 — 15 years by the start of treatment | Air charge-up time to 6.5–8 atm, oil temperature in the system, outlet air temperature |
Measurements before treatment and after 300 hours of operation
| PARAMETER | BEFORE | AFTER | CHANGE |
|---|---|---|---|
| Air charge-up time, 6.5–8 atm | 55 s | 50 s | output +10 % |
| Oil temperature in the system | 80 °C | 60 °C | −20 °C |
| Outlet air temperature, start of run | 55 °C | 54 °C | −1 °C |
| Outlet air temperature, end of run | 60 °C | 58 °C | −2 °C |
The “before” and “after” measurements were taken in service by the plant chief mechanic together with the XADO LLC representative.
