At EKG M&E Sdn Bhd, we provide professional unloader valve repair services for air-cooled chiller compressors, ensuring precise capacity control, smooth start-up, and optimal system efficiency. The unloader valve plays a critical role in regulating refrigerant flow and reducing compressor load during operation. When this component malfunctions, it can cause performance issues, excessive wear, and energy waste.
Ensures accurate compressor capacity control
Prevents hard starts and overloading
Reduces energy consumption and cycling stress
Protects internal compressor components from strain
Supports smooth and stable cooling performance
Valve stuck in open or closed position
Intermittent or failed actuation during load/unload cycles
Leaking unloader piston or diaphragm
Solenoid coil failure or electrical fault
Oil or refrigerant contamination affecting valve movement
Compressor short cycling or failing to unload
Inconsistent suction pressure or refrigerant flow
High amperage draw during start-up
Cooling capacity drops under part-load conditions
Unusual vibration or noise during load transitions
Diagnosis and Inspection
We begin by inspecting the unloader system, testing the solenoid coil, pressure response, and valve actuation. We use:
Electrical testing equipment
Suction/discharge pressure monitoring
Thermal and vibration analysis
Component Repair or Replacement
Based on our findings, we:
Clean or replace blocked or contaminated valve components
Repair or install new solenoid coils or valve actuators
Replace gaskets, springs, pistons, or diaphragms as needed
Adjust timing or pressure control settings for accurate operation
Testing and Recommissioning
After repairs, we verify:
Proper valve actuation and sealing
Smooth load/unload performance
Stable operating pressures
Balanced compressor cycling and current draw
Restores full compressor functionality and efficiency
Reduces mechanical stress and energy usage
Improves part-load performance and system responsiveness
Prevents future breakdowns or electrical overload
Supports reliable and optimized HVAC operation
Experts in compressor control and valve systems
Experience with scroll, screw, and reciprocating compressors
Familiar with all major air-cooled chiller brands and valve types
Quick turnaround and precision repair work
Full support from diagnosis to performance validation
A faulty unloader valve can quietly drain performance and drive up costs. With EKG M&E Sdn Bhd’s air-cooled chiller compressor unloader valve repair, you restore smooth, efficient operation and avoid bigger problems down the road. Contact us today to schedule an inspection or repair service.
