HJ177 Evaporator Condenser Vacuum Chamber Helium Testing Equipment
High Precision Leak Detection ISO 20485 Certification
Product Introduction:
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.
Product Features:
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.
