Helium Leak Detector (Accommodating the whole unit of the absorption chiller or heat pump)
Absorption Chiller operates in high vacuum condition. The helium leak test is essential to ensure a perfect vacuum condition throughout production. Before the finished absorption unit leaves factory, it is tested as a whole by our helium mass spectrometer to ensure high air tightness. Various tests show that SHUANGLIANG equipment is strictly air tight, which ensures the unit’s extended use life. As a matter of fact, SHUANGLIANG is one of the first to apply helium mass spectrometer to test the whole unit in China central air conditioning industry.
