HeJin original factory direct vacuum chamber helium leak testing equipment for evaporators, condensers, automotive radiators, and heat exchangers. Delivers ultra‑high precision micro‑leak detection, stable mass production performance, full compliance with ISO 20485, and complete pre‑sales and after‑sales support for automotive, refrigeration, and HVAC manufacturing.

For manufacturers of evaporators, condensers, radiators, and heat exchangers, even micro leaks lead to performance failure, warranty claims, and safety risks. HeJin HJ177 vacuum chamber helium leak testing equipment uses helium as a tracer gas in a high‑vacuum test chamber to detect micro leaks that traditional methods miss. As a direct manufacturer, HeJin integrates R&D, production, and service to provide stable, efficient, and traceable leak detection for mass production lines, helping you meet OEM quality standards and reduce defect rates.

• Ultra‑high detection sensitivity: Captures micro leaks invisible to conventional methods
• ISO 20485 certified: Fully compliant with international tracer gas leak test standards
• Stable for mass production: Designed for 24/7 industrial line operation
• Helium saving & high recovery: Efficient recovery lowers operating cost
• Intelligent operation: Simplified workflow reduces operator error

• ISO 20485:2017 Non‑destructive testing — Leak testing — Tracer gas methodISO
• ISO 9001 Quality management systems

• Automotive air conditioning systems: evaporators, condensers, radiators
• Refrigeration & HVAC: heat exchangers, compressor parts
• Auto parts: engine coolers, oil coolers, pipeline assemblies

What’s the difference between helium leak testing and traditional methods?

Helium detects micro leaks; traditional methods only find large leaks. Helium ensures long‑term reliability.

Is this equipment suitable for mass production lines?

Yes, optimized for 24/7 stable operation with short takt time.

Can you test different sizes of evaporators/condensers?

Customizable chamber and tooling for your workpiece dimensions.

How high is the helium consumption?

With recovery ≥98%, operating cost is greatly reduced.

How long is delivery and installation?

Standard models in stock; custom units 60-90 days; fast on‑site commissioning.
