Ex vacuum leak detector in a two-part version: The leak detector (working unit) is explosion-proof and can be installed in Ex zone 1. The leak indicating unit LAE (for 1 up to 8 leak detectors) is installed outside an Ex area.
VLX 34 A-Ex for tanks with a suction line to the low point of the interstitial space
VLX 330 A-Ex for horizontal tanks with up to 3 meters diameter and without a suction line to the low point of the interstitial space as well as for flat bottom tanks
- Single-walled tanks with a leak protection lining or jacket
- Double-walled horizontal and vertical tanks
- Double-walled bottoms of flat bottom tanks
Water-polluting liquids. The (possible) explosive vapor-air mixtures (also such ones that can arise through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II B3 as well as in the temperature code T1 to T3 (T4 on request). Example: petrol.
