High-Precision Helium Leak Testing for Heat Pump Manufacturing
A leak that is too small to see can still become a real production problem.
For heat pump components and other sealed parts, airtightness directly affects the stability of the finished assembly. Conventional visual inspection or basic pressure testing may not provide enough information when manufacturers need a more controlled leak inspection process.
The High-Precision Heat Pump Helium Leak Testing Equipment developed by HeJin combines helium tracer-gas testing with vacuum and pressure-hold testing methods to provide a controlled inspection process.
Helium is widely used as a tracer gas for leak detection because it can be selectively detected by dedicated leak detection systems.
ISO 20485:2017 defines tracer-gas leak testing as a method using a tracer gas and a tracer-gas-specific leak detector. The standard describes both situations where tracer gas flows into the test object and where tracer gas flows out of the test object.
For production environments, this means manufacturers can establish a defined test process around:
ISO 20485:2017 — Non-destructive Testing — Leak Testing — Tracer Gas Method
This is the most directly relevant international reference for helium tracer-gas leak testing.
ISO states that ISO 20485:2017 describes techniques for detecting leaks using a tracer gas and a tracer-gas-specific leak detector.
ISO 20486:2017 — Calibration of Reference Leaks for Gases
ISO 20486:2017 addresses the calibration of reference leaks used for adjustment of leak detectors and determination of leakage rates.
ISO 9001:2026 — Quality Management Systems
ISO 9001:2026 is the current edition of ISO 9001 and specifies requirements for quality management systems, including processes for customer requirements, operational control, performance evaluation and continual improvement.

For a production-line testing project, buying the equipment is only one part of the decision. Fixture development, test-process definition, commissioning, training and after-sales support can be equally important.
HeJin states that it is a technology-driven manufacturer specializing in R&D, manufacturing and sales of industrial testing equipment. The company was established in Guangzhou in 2012 and provides helium leak detection systems, automotive testing equipment and other industrial testing solutions.
Customers can work directly with the manufacturer instead of relying only on a trading intermediary.
HeJin states that it has its own R&D and design team and supports customized equipment development according to customer requirements.
HeJin's factory information covers equipment production, assembly and commissioning, with engineering support for customer projects.
Leak testing is rarely a simple "one machine fits every product" application. Workpiece dimensions, sealing structure, internal volume, test criteria and production cycle all affect the final configuration.
HeJin states that its technical and sales teams provide global after-sales support for equipment supplied to customers.
Q1: What is the main purpose of this helium leak testing equipment?
It is designed for controlled leak and airtightness inspection using helium tracer gas, vacuum testing and positive/negative pressure hold conditions.
Q2: Can the equipment store testing data?
Yes. Data can be stored through the scanner and host computer, with functions for querying, retrieving and modifying records.
Q3: How are NG products handled?
The equipment includes a red NG box with locking and material-warning functions. The specification also states that NG products should not enter the next test cycle.
Q4: Can the equipment test different products?
Yes. The supplied configuration includes two sets of product tooling, and different products require tooling replacement.
Q5: Can HeJin customize the equipment?
HeJin states that its R&D and design team can develop customized equipment according to customer requirements.
Q6: Can the equipment be integrated into a production line?
The equipment is designed for production-oriented testing, and HeJin's product portfolio includes automated and semi-automated testing solutions. Final integration requirements should be confirmed according to the customer's production line.
Q7: How many product fixtures are included?
The specification states that two sets of product tooling are provided.
