Home BlueBox LeakProof – Integrity and Helium Leak Test

Helium Leak Testing Systems

Why helium leak testing? 

Your goal is to find and repair a leak prior to the evacuation and charge process, eliminating the costly rework and the compromised quality that comes from repairing a leak in a charged unit. LeakProof™, ECIMOS Integrity and Helium Leak Testing Systems, are located immediately after the assembly and brazing of the refrigeration circuit. These helium leak testing systems may also be located in coil sub-assembly areas.  LeakProof’s sequence of operation is computer-controlled, its parameters are model specific, and it satisfies the requirements of “UL”. Integrate it with ECIMOS Brazer Performance Tracking System to qualify or disqualify brazers.

Powered by ECIMOS manufacturing operating system, LeakProof is able to keep track of the following parameters:helium leak test station

• Unit Serial Number
• Unit Model Number
• Error Message for failed units
• Component Description
• Serial Number
• Component Model
• Pass/Fail Status
• Test Date
• Operator that tested unit
• Cycle Time
• Leak Detector Verification
• Evacuation Pressures and Times
• Helium Pressures and Fill Times
• Decay Parameters
• Vent Parameters
• Helium Sniff Time

LeakProof’s software allows for flexible configurations. Convenient drop-down menus allow administrators to configure the station to pull information from an external bill of materials, for instance.

There is also a Manual I/O program. Its outputs let you control the station manually for system maintenance and troubleshooting.
