One of the clients of CTRL Systems, Inc. is an industry leader in the design, engineering, manufacturing, integration, modification, testing, and repair of tactical shelters, modular containers, and custom enclosures.
After pre-screening 100% Gichner Systems Group, through its Gichner Shelter Systems and CMCI subsidiaries, is the industry leader in the design, engineering, manufacturing, integration, modification, testing, and repair of tactical shelters, modular containers, and custom enclosures.
Each of the constructed shelters is tested for leaks by quality control. The shelters are run through a rain shed to determine if any water gets inside. It is imperative that the shelters are leak proof since they could be used in various climates to store mission critical electronic equipment.
The staff was trained on use and operation of the UL101 and UT2000 ultrasound test equipment for testing non-pressurized vessels for leaks. After pre-screening 100% of the shelters with the ultrasound method, they were passed through normal quality control procedures. There was a "very good correlation" between the ultrasound leak checking and the actual rain test results.
As a confidence trial, three additional shelters were tested with ultrasound that had known leaks. The UL101 found each of the leakage points. All three containers were then tested with the rain system and showed the same results.
Using the UL101 and UT2000 helped reduce the rain test sample rate from 100% to just one rain test per day, saving an enormous amount of labor costs and time.
