At EKG (Malaysia) Sdn Bhd, we offer professional refrigerant leak pressure testing for air-cooled chillers to detect hidden leaks, verify system integrity, and ensure your chiller operates at peak cooling efficiency and safety standards. Pressure testing is a highly accurate method used to identify refrigerant leaks that cannot be seen or heard, especially in hard-to-access areas or systems with slow gas loss over time.
1. Accurately Detects Hidden Leaks
Ideal for early-stage or slow refrigerant leaks that traditional inspections may miss.
2. Prevents System Inefficiency
Ensures refrigerant is maintained at the correct pressure, optimizing cooling output and reducing power consumption.
3. Protects Critical Components
Prevents compressor strain, coil icing, and system imbalance caused by low refrigerant levels.
4. Supports Preventive Maintenance
Identifies weaknesses or potential failure points before they become major issues.
5. Ensures Safety & Compliance
Pressure testing helps comply with HVAC safety regulations and refrigerant handling standards.
1. System Shut-Down & Preparation
We isolate and prepare the chiller system for safe pressure testing, recovering refrigerant if needed.
2. Nitrogen Pressure Charging
The system is filled with dry nitrogen to a specific pressure rating suitable for the unit, simulating operating conditions without using actual refrigerant.
3. Pressure Monitoring & Leak Detection
The system is monitored for pressure drops over time, indicating the presence of a leak. We also use soap bubble solution and electronic sensors at suspect points for confirmation.
4. Component Inspection
If a leak is detected, we inspect valves, joints, coils, fittings, and welds to pinpoint the exact source of the problem.
5. Leak Repair & Retesting
After repair, the system is retested under pressure to confirm that it is leak-free and ready for refrigerant recharge.
6. System Recharging & Final Testing
We recharge the system with the correct refrigerant and perform final cooling and efficiency tests.
1. Specialists in Chiller Diagnostics
Our team is highly experienced in air-cooled chiller leak detection and refrigerant system maintenance.
2. Advanced Tools & Safety Protocols
We use certified equipment and follow strict safety procedures during pressure testing.
3. Fast & Reliable Service
Minimize downtime with our efficient troubleshooting and repair workflow.
4. Environmentally Responsible
We handle refrigerants according to green HVAC practices, using low-GWP, non-ozone-depleting alternatives.
5. Complete Chiller Solutions
From leak testing to refrigerant recovery, repair, and system optimization, we offer full support.
Refrigerant leaks can silently degrade your air-cooled chiller’s performance, driving up energy costs and risking system failure. At EKG (Malaysia) Sdn Bhd, our pressure testing service is a reliable, accurate way to detect leaks and keep your cooling system operating at its best.
