Refrigerant Pressure and Charge Inspection

Verifying Charge Level Against Actual System Conditions, Not Just a Pressure Glance

A pressure reading that looks acceptable at a glance can still mask an incorrect refrigerant charge, since the right assessment depends on comparing pressures against actual operating conditions rather than a fixed number. EKG M & E Sdn Bhd provides refrigerant pressure and charge inspection for building owners and facility managers across Malaysia, verifying charge level properly rather than assuming it from pressure alone.

What We Offer

🔍 Site Assessment & System Review
We assess the AHU refrigerant circuit on site, reviewing system type, refrigerant, and operating conditions before taking readings.

📊 Suction & Discharge Pressure Measurement
We measure suction and discharge pressures using calibrated gauges, comparing readings against expected values for the refrigerant type and load conditions.

🌡️ Superheat & Subcooling Calculation
We calculate superheat and subcooling from pressure and temperature readings, confirming whether the charge level is correct for the system's design.

⚙️ Load Condition Correlation
We correlate pressure readings against actual load conditions at the time of inspection, since pressures and correct charge assessment vary with ambient and system load.

🔧 Expansion Valve Function Check
We check expansion valve operation as part of the inspection, since valve issues can mimic incorrect charge symptoms even with adequate refrigerant present.

💨 Airflow Correlation Check
We check airflow across the evaporator coil, since restricted airflow can produce pressure readings that resemble a charge-related issue.

🔩 Compressor Condition Cross-Check
We cross-check compressor condition against pressure readings, since certain compressor faults present through specific pressure patterns.

💧 Moisture & Contamination Check
We check for indicators of moisture or contamination in the refrigerant circuit that could be affecting pressure readings and charge assessment.

📋 Inspection Report
You receive a clear report recording pressures measured, calculated superheat and subcooling, and findings on charge level against expected values.

🗓️ Scheduled Re-Inspection
We offer scheduled re-inspection to track pressure and charge trends over time, catching gradual drift before it becomes a significant issue.
