Centrifugal Air Compressor Maintenance
July 25, 2023


Effective maintenance is the key to ensuring optimal performance, minimizing breakdowns, and enhancing energy efficiency for your centrifugal air compressor. Explore our comprehensive maintenance services tailored to address critical components, such as rotors and cooler elements, ensuring your compressor operates at peak efficiency.

Centrifugal Air Compressor Maintenance Service Highlights:

While centrifugal air compressors have fewer internal moving components compared to other types, focused attention on specific areas is crucial. Our maintenance and inspection services prioritize two key elements: rotors and cooler components. Here are the key features of our maintenance service:

  1. Debris Inspection:
    • Thorough examination for inorganic debris or corrosive acids.
    • Prevents fouled cooler tubes, maintaining optimal performance.
  2. Cooler Performance Check:
    • Regular measurement of Cold Temperature Difference (CTD).
    • Ensures the CTD is 15 degrees Fahrenheit or greater for efficient cooling.
  3. Moisture Check:
    • Inspection of water and air-sides, ensuring cleanliness.
    • Examination of condensate drain to preserve compressed air quality.
  4. Condensate Removal Inspection:
    • Ensures a clean condensate removal system to prevent contamination.
    • Safeguards against potential damage to diffusers, impellers, and intercooler fins.

Additional Maintenance Checks (Non-exhaustive):

  • Condensate drain examination.
  • Alarms and trips evaluation.
  • Operating data review (Rotor vibration, temperatures, etc.).
  • Air/oil leak inspection.
  • Detection of unusual noises (motor irregularities, gasket leaks, impeller rub, compressor surge).
  • Replacement of air filter elements, oil filter elements.
  • Quarterly oil sample collection for analysis.
  • Control panel history assessment, analyzing alarms and trips.
  • Inspection and cleaning of intercooler/aftercooler tubes, with gasket and seal replacements.
  • Driver motor bearing maintenance, couplings greasing, and fastener torque checks.
  • Inlet and unloading valves inspection and testing, with linkage and bearing greasing.
  • Discharge check valve inspection.

Note: All maintenance services adhere strictly to OEM recommendations and service intervals.
