The SUNHOPE Automatic Dry Radiator Leak Testing Machine is designed for high-precision inspection of automobile radiator tanks and cooling components. Using advanced trace-gas detection technology, it provides fast, non-destructive, and contamination-free leak testing without water or oil.

With molecular-level sensing, a 1-second sensor response, and low-cost tracer gas, the machine helps radiator manufacturers improve inspection efficiency while reducing testing costs.

• High-Precision Leak Detection – Proprietary TR3.0 molecular-level trace sensing technology analyzes air background values to identify even small micro-leaks.
• 1-Second Sensor Response – Fast sensor response helps shorten testing cycles and improve production throughput.
• 1/20 Tracer Gas Cost – The selected tracer gas costs only 1/20 of traditional helium, significantly reducing consumable costs.
• Dry & Clean Testing – No water or oil is required, helping prevent contamination and supporting clean, oil-free testing environments.
• Easy HMI Operation – An intuitive Human-Machine Interface simplifies operation and reduces operator training requirements.
• Automatic & Manual Modes – PLC control supports consistent automatic testing while allowing manual operation when required.
• Customizable Configuration – The machine can be adapted to radiator dimensions, testing requirements, and production-line layouts.
