Proper refrigerant balancing is critical for maintaining optimal cooling performance, energy efficiency, and system longevity in air-cooled chillers. An imbalanced refrigerant charge—whether undercharged or overcharged—can lead to reduced heat transfer, excessive energy consumption, compressor strain, and possible system failure.
EKG (Malaysia) Sdn Bhd provides professional refrigerant balancing services, ensuring precise refrigerant levels, optimal pressure settings, and maximum chiller efficiency.
Our ISO-certified refrigerant services cater to:
Industrial & Manufacturing Facilities
Commercial Buildings (Offices, Malls, Hotels, Hospitals)
Data Centers & IT Cooling Systems
Pharmaceutical & Healthcare Cooling
Food Processing & Cold Storage Units
1. Inconsistent Cooling Performance
Chiller struggles to maintain setpoint temperatures
Uneven cooling or fluctuating discharge air temperature
2. Increased Energy Consumption
Higher electricity bills due to compressor overworking
Loss of efficiency leading to excess power usage
3. Ice Formation on Evaporator Coils
Ice buildup on evaporator or suction lines indicates improper refrigerant flow
Low refrigerant levels cause poor heat absorption
4. Short Cycling & Frequent Compressor Shutdowns
Chiller turns on and off too often, reducing lifespan
Overcharged refrigerant can trigger high-pressure cutoffs
5. Unusual Noises from the Chiller System
Hissing or bubbling sounds indicate low refrigerant pressure or gas leaks
High-pressure noises can be a sign of overcharging
6. High or Low Suction & Discharge Pressures
Low suction pressure suggests undercharged refrigerant
High discharge pressure indicates excess refrigerant in the system
7. Overheating & Compressor Failure Risks
Compressor running hotter than normal due to refrigerant imbalance
Reduced lubrication, causing mechanical wear and tear
1. System Inspection & Pressure Testing
Conduct refrigerant pressure diagnostics using precision HVAC gauges
Check suction and discharge pressures for proper refrigerant balance
Perform superheat and subcooling analysis to assess refrigerant flow
2. Leak Detection & Refrigerant Loss Assessment
Use electronic leak detectors and thermal imaging to identify refrigerant leaks
Inspect compressor, condenser coils, expansion valves, and refrigerant lines
Seal micro-leaks and replace faulty valves or fittings
3. Refrigerant Charge Adjustment & Optimization
Refill or recover refrigerant to achieve manufacturer-recommended levels
Ensure accurate refrigerant charge based on system tonnage and heat load
Prevent undercharging or overcharging to avoid system inefficiencies
4. Expansion Valve & Compressor Calibration
Adjust expansion valve settings for proper refrigerant flow regulation
Optimize compressor cycling to improve cooling efficiency
Monitor suction and discharge pressures for system stability
5. Performance Testing & System Validation
Conduct load testing and cooling efficiency analysis post-balancing
Monitor compressor operation, refrigerant circulation, and system pressure levels
Provide detailed reports and long-term maintenance recommendations
