Air-cooled chiller low-pressure compressor service

Air-Cooled Chiller Low-Pressure Compressor Service | EKG (Malaysia) Sdn Bhd

Why Low-Pressure Compressor Service Is Important

• Restores optimal cooling performance

• Prevents compressor overload and long-term damage

• Improves energy efficiency and system responsiveness

• Supports proper refrigerant flow and oil return

• Reduces downtime and emergency repair costs

Common Causes of Low Compressor Pressure

• Refrigerant undercharge or leakage

• Restricted refrigerant flow (clogged filters or valves)

• Evaporator coil freeze-up or low air flow

• Expansion valve malfunction (TXV/EXV stuck or failing)

• Suction line blockage or oil logging

• Faulty pressure sensors or control settings

Symptoms of Low-Pressure Issues

• Compressor runs continuously or short cycles

• Ineffective cooling output at air handler or space

• Frost or ice buildup on suction lines or evaporator

• Low suction pressure on gauges during operation

• Increased power consumption and motor strain

Our Low-Pressure Compressor Service Includes

• System Diagnosis
  We begin with a complete pressure, temperature, and flow analysis using:

  • Digital gauges and refrigerant analyzers

  • Superheat and subcooling measurements

  • Airflow and coil temperature checks

• Refrigerant Leak Testing & Recharge
  If a refrigerant shortage is identified, we perform:

  • Leak detection using electronic or UV dye methods

  • Refrigerant top-up or full recharge using the correct type and charge level

• Component Inspection & Repair
