Functions of Big Blu Microleak Detector:
1. Detects Small Gas Leaks (Microleaks)
• Big Blu Leak Detector is designed to detect tiny gas leaks that are invisible to the naked eye.
• Suitable for refrigerants, high-pressure gases, or air.
• When sprayed on pipe joints, bubbles will form if there is a leak – the bubbles won’t break and will grow larger if leakage is present.
.;
2. Usable in Cold or Hot Temperatures
• Remains effective from -28°C to 121°C.
• Suitable for outdoor units and chiller systems.
• Can be used while the system is running (under active pressure).
.;
3. Safe for All Metals
• Won’t damage copper, iron, aluminum, brass, or stainless steel.
• Non-corrosive and safe on gaskets or O-rings.
.;
4. Long-Lasting & Doesn’t Dry Quickly
• Big Blu has a high-viscosity formula – sticks strongly to surfaces without dripping away too fast.
• Makes bubbles highly visible even for very tiny leaks (micron level).
.;
5. Ideal for Routine Checks & New Installations
• Technicians commonly use Big Blu:
• After vacuuming and charging refrigerant
• During routine maintenance inspections
• When performing pressure tests after pipe installation
.;
How to Use Big Blu Leak Detector:
1. Spray or apply Big Blu on connections / flare nuts / joints.
2. Observe the area for a few minutes.
3. If bubbles form and don’t burst → a leak is confirmed.
4. Mark the spot for repair (tighten or replace the component).
Why Technicians Prefer Big Blu:
• More accurate than regular soap water – bubbles don’t break.
• Long-lasting & capable of detecting leaks as small as 0.65 mbar/sec!
• Essential when performing vacuum + refrigerant charging (R410A, R32, etc.).
