Application:
The receiver drier helium leak detector is mainly designed to deliver gas tightness test for automatic air conditioning receiver drier. If altering the fixture, the system could also be used to test automotive air conditioning evaporator, condenser and compressor. With the receiver drier leak detector, air tightness of automotive components will be well guaranteed, and the leakage of horizontal substances (refrigerant) will be well avoided.
In accordance to the basic principle of helium leak detection, we adopt helium, rather than Freon, as the tracer gas. After charging helium into the testing object within vacuum pump, the helium leak detector will be adopted for leak testing. The testing method features high precision and fast detection.
The receiver drier helium leak detector is equipped with two vacuum pumps, and each of them is outfitted with 6 sets of couplings. The design highly increases the detection efficiency. Meanwhile, a helium recovery device is also installed on the system, effectively saving the helium costs.
