Air-Cooled Chiller Low-Pressure Compressor Service – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer expert low-pressure compressor services for air-cooled chillers, addressing performance issues that can lead to insufficient cooling, increased energy consumption, and potential compressor damage. Low suction pressure in a chiller’s compressor is often a sign of underlying system imbalances, leaks, or mechanical faults—and requires prompt, accurate intervention.

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
We inspect and service:

• Expansion valves and capillaries

• Suction filters and driers

• Evaporator coils and airflow systems

• Pressure switches, transducers, and control logic

Post-Service Testing
We confirm:

• Stable suction pressure within design range

• Correct refrigerant flow and oil return

• Balanced load and efficient compressor operation

• No further signs of leakage or restriction

Benefits of Our Service
