electrical
• Couple coupling main motor and compressor and Test Running. Support team CS
• Rotate manual shaft main motor by hand after couple, ensure freely and check trend vibration. Support team CS
• Open the gate valve for cooling water supply. Check and ensure for water leaks.
• Did valve calibration (especially for IGV and BOV).
• Test natural surge
a. Inlet Valve 100% Open
b. Bypass Valve 26 % Open
c. Previous Surge Press. Result 181 psi

• Test throttle surge.

a. Inlet Valve 33% Open, Bypass Valve 33% Open
b. Amper Main Motor 43,5 Amp
c. In Setpoint 110 psi

Our Recommendation

• Again, we suggest did monitoring 4 times per day to ensure compressor is running well and report if any anomalies
phenomenon on compressor.
• Suggest replacing oil filter element at first 250 hours after commissioning.
• Suggest check condensate trap every 4 hours, to ensure the condensate is coming out to atmosphere. For normal
conditions the bypass valve should be fully close. Concerned for optimize compressor efficiency.
• Repair the storage gutter to install a removable cover to make it easier to monitor the water volume and function of the
water condensate trap.
