Vacuum Chamber Helium Leak Detection System for Automotive Air-conditioning Compressors

1. 4 Vacuum Chambers, which ensure fast cycle
2. 20% helium tracer gas, that saves helium consumption
3. System sensitivity 1g/Year(R134a)

Application

This system is suitable for air-tightness detection of compressors of automotive air-conditioner. It can also be used for compressors of household refrigerator and air-conditioner to ensure the airtightness of the product and avoid the leakage of harmful substances (refrigerant).  

Principle

According to the basic principle of helium leak detection, with helium as the tracer gas, helium is filled into the workpiece in the vacuum chamber, and then the helium leak detector can accurately and quickly judge the leakage of the workpiece.

System Process

Operator puts the workpiece in the vacuum chamber, then connects the workpiece interface with the quick connector. After the door of vacuum chamber is closed, the system can automatically complete the whole process like large leakage and strength detection, air exhaust, helium filling, Helium recovery and so on. High precision, easy operation and fast test cycle make our helium leak test system is widely adopted by manufacturers.
