The Radiator Leak Testing Machine is designed to ensure every radiator leaving your production line is perfectly sealed. By filling the radiator with dry compressed air and monitoring pressure changes, it can quickly detect leaks—no guesswork involved.

Its dual-station design, simple operation, and reliable performance make it ideal for automotive radiator manufacturers, heat exchanger factories, and quality control departments. The machine helps improve inspection efficiency, reduce defective products, and maintain consistent product quality.

With integrated data storage and a user-friendly interface, operators can test radiators quickly and record up to 100,000 sets of test data, ensuring complete traceability for quality management.

• High-Precision Leak Detection
  Uses pressure decay technology to detect even minor leaks, ensuring defective radiators are identified before shipment.
• Dual-Station Operation
  One station can run tests while the other is being loaded or unloaded, maximizing production efficiency.
• User-Friendly Controls
  Operators can set test parameters, start cycles, and view results instantly—no extensive training required.
• Large Data Storage
  Stores up to 100,000 test records for full quality traceability.
• Stable Industrial Performance
  Designed for continuous use in production environments, providing consistent and reliable results.

1. Connect the radiator to the testing fixture.
2. Fill it with dry compressed air.
3. Stabilize the pressure inside the radiator.
4. Monitor pressure changes over the test cycle.
5. If pressure loss exceeds preset limits, the radiator is flagged as defective.
6. Pass/fail results are displayed instantly, and testing data is stored automatically.

This non-destructive testing method ensures every radiator remains intact while guaranteeing quality.

Note: Detailed dimensions and weight can be customized according to your radiator specifications.

The machine is suitable for a wide range of radiator and heat exchanger products, including:

• Automotive radiators
• Aluminum radiators
• Copper-brass radiators
• Truck and heavy-duty vehicle radiators
• Industrial heat exchangers
• OEM and aftermarket radiator inspection

In a radiator production line, the leak test is usually performed after core assembly, brazing, and final assembly. The Radiator Leak Testing Machine helps operators identify defective radiators before packaging and shipment. Its fast testing cycle and dual-station design allow continuous production without bottlenecks.

Even a small leak can lead to coolant loss, reduced cooling efficiency, engine overheating, and customer complaints. Reliable leak testing helps manufacturers:

• Maintain product quality
• Reduce warranty claims
• Enhance customer satisfaction
• Strengthen brand reputation

By identifying sealing defects early, manufacturers reduce quality risks and ensure only reliable radiators reach customers.
