This equipment is suitable for dry leak detection of two air conditioners (evaporator and condenser). Use nitrogen or dry compressed air to test the compressive strength and large leak tightness of the inspected workpiece, pre-evacuate and fill the inspected workpiece with helium, use the vacuum box method to perform helium mass spectrometry air tightness detection, and then recycle the helium in the inspected workpiece. The device can be used to determine the leak rate of the inspected workpiece and whether it is qualified or unqualified.
Why do we need helium inspection? -- Use technology to protect every bit of safety
In the world of refrigeration systems, micron-level leaks may mean energy waste, performance degradation, and even safety hazards. HJ177 is not only a device, but also a "safety sentinel" for your production line. We are well aware that the sealing of the evaporator and condenser is related to product life and environmental responsibility, so we use the ultimate precision of helium inspection technology to give confidence to your quality commitment.
