Product Introduction

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.

Why Helium Leak Testing?

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:

• Controlled helium concentration
• Defined charging pressure
• Vacuum chamber conditions
• Pressure difference across the test object
• Leak-rate evaluation

International Reference Standards

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.

Technical Specifications

Why Choose HeJin as the Source Manufacturer?

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.

Direct Factory Supply

Customers can work directly with the manufacturer instead of relying only on a trading intermediary.

R&D and Design Capability

HeJin states that it has its own R&D and design team and supports customized equipment development according to customer requirements.

Manufacturing Capability

HeJin's factory information covers equipment production, assembly and commissioning, with engineering support for customer projects.

Application Engineering

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.

Global After-Sales Support

HeJin states that its technical and sales teams provide global after-sales support for equipment supplied to customers.

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.

About HeJin

Your Direct Source Manufacturer for Leak Testing Equipment

HeJin — HJ AUTOMATIC CONTROL TECHNOLOGY CO., LTD — is a Guangzhou-based manufacturer specializing in the research, development, design, manufacturing and sales of industrial testing equipment.

Established in 2012, HeJin provides testing solutions for automotive, refrigeration, home appliance, electronics and other industrial applications. The company's product portfolio includes Leak Testing Equipment, helium leak detection systems, auto parts test equipment, environmental testing equipment and other customized testing solutions.

Unlike a trading-focused supplier, HeJin integrates R&D, engineering design, manufacturing, sales and technical service within its business operation. This allows customers to communicate directly with the manufacturer when discussing product requirements, tooling, testing methods, equipment configuration and production-line integration.

R&D and Engineering Capability

Every leak-testing application is different.

The workpiece size, sealing structure, internal volume, required leak rate, testing pressure, cycle time and production environment can all influence the equipment configuration.

HeJin has an internal professional design team and engineering capabilities for developing testing solutions according to customer requirements. The company also states that it develops customized testing solutions tailored to specific products and compliance requirements.

For helium leak testing projects, this means customers can discuss not only the machine itself, but also the testing process, product tooling, chamber configuration, data management and production requirements with the engineering team.
