Refrigerant Leak Detection in Johannesburg
Electronic and pressure leak detection across refrigeration pipe runs, evaporators and condensers to locate and seal refrigerant loss.
Johannesburg is the densest commercial refrigeration market in Gauteng, with high concentrations of restaurants, hotels, retail and food manufacturing sites that depend on uninterrupted cold chain.
Diagnostic Process
The structured sequence we follow on every leak detection call — to isolate the root cause, not just the symptom.
- 01Electronic leak detector sweep of all brazed joints and fittings
- 02Bubble solution on accessible joints and schrader valves
- 03Pressure-decay test and nitrogen pressure hold where required
- 04UV dye trace for intermittent or slow leaks
- 05Inspect evaporator and condenser coils for corrosion and pinholes
- 06Log leak location, repair and re-test with full charge verification

Refrigerant Leak Detection Johannesburg — FAQ
How do you find a refrigerant leak?
We combine electronic detection, bubble solution, nitrogen pressure-decay and UV dye tracing depending on whether the leak is active, slow or intermittent.
Is a refrigerant leak dangerous?
Most commercial refrigerants are not acutely toxic at low concentration but displace oxygen in confined plant rooms and indicate a system losing capacity. Leaks should be repaired promptly.
How quickly can a Reyds technician reach Johannesburg for leak detection?
