The VLT-ST (standard model) is designed for high precision air-water tightness tests of packages, or for vacuum simulation tests.
Tests can be performed on all kind of packages: glass or PET bottles, PET–preforms, ALU or other metal or plastic caps, cans, pouch and blister packages, etc.
The box is made of polished transparent PMMA and is of very rugged design. Several standard dimensions are available covering most part of tasks; special dimensions request welcomed.
VLT is delivered with a venturi vacuum generator which runs at 6 bar pressurized air. Optional is a high performance electric vacuum pump, which provides a vacuum until -999 mbar.
For under water tests the immersion set completes the system.
The handling via touch screen is easy and safe, there steps, peak vacuum values and holding times setting and displaying of the real-time vacuum value. The target vacuum and vacuum holding time for each step can be freely pre-defined. Usually 2 stages of vacuum and holding time can be pre-set, optionally 3 stages. VLT vacuum regulating accuracy is 0.5%.
Vacuum will be stopped automatically after the test and the start button light will be off.
The VLT in the VLT-PLC version offers additionally the possibility to store product name, the operator, a lot and sample no.
