At Anhui Daxin Vacuum Technology Co., Ltd., we pride ourselves on delivering-edge helium leak detection equipment tailored for industrial applications. In September 2025, we partnered with Mexico’s CIPSA Group to provide a customized sniffing method helium leak detection and recovery system for stainless steel pipe fittings, ensuring superior cutting airtightness and efficiency in their manufacturing process.

This advanced system integrates multiple functions: high-pressure nitrogen/compressed air filling for gross leak detection (up to 100 psi, e.g., 25 psi), vacuum evacuation (absolute pressure ≤1000 Pa), helium charging (up to 100 psi, e.g., 25 psi), manual suction gun helium mass spectrometer leak detection, and helium recovery with recycling. Designed for workpieces with inner cavity volumes ≤20 L, it supports dual-branch operation for simultaneous testing of two pieces, achieving a cycle time of ≤2 minutes per piece (based on 3L volume). The detection leak rate is ≤1.0×10⁻⁵ mbar·L/s, with a helium recovery rate ≥98% and real-time concentration monitoring (≥70%, adjustable with alarms).
Controlled via PLC with a bilingual (Chinese-English) touch screen, the system features reliable interlocks, fault statistics, and password protection for secure parameter management. It accommodates capillary-equipped workpieces using NPT 1/4 quick connectors for seamless integration.

This collaboration highlights our expertise in helium leak testing for HVAC components like condensers and evaporators, as well as power and liquid cooling plate applications. CIPSA benefited from online installation, training, and a 1-year warranty (excluding consumables), with lifelong technical support.
