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.
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
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
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
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
Ensures stable, efficient cooling performance
Prevents compressor wear and electrical overloads
Reduces energy bills and maintenance frequency
Increases system reliability and operational life
HVAC experts in compressor pressure diagnostics and repair
Advanced tools for accurate system analysis and optimization
Experience with scroll, screw, and reciprocating compressors
Service for all major air-cooled chiller brands
Responsive support and transparent service reports
