VLXE .. A-Ex MV

For increasing, move mouse over the picture

Ex vacuum leak detector in a two-part version: The leak detector VLXE .. A-Ex MV is weather- and explosion-proof and can be installed in Ex zone 1.

The versions VLXE .. A-Ex MV or VLXE .. A-Ex MV with ZD allow overpressures in the interstitial space of up to 25 bar or up to 90 bar, respectively.

The associated weatherproof leak indicating unit LAE .. PMMV with integrated digital manometer and leak tightness detection function is installed outside an Ex area.

TYPES of leak detectors:

VLXE 34 A-Ex MV for tanks with a suction line to the low point of the interstitial space

VLXE 330 A-Ex MV 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

(other pressure settings are available)

TYPES of leak indicating units:

LAE 34 PMMV, LAE 330 PMMV

(other pressure settings are available)

TANKS:

Single-walled tanks with a leak protection lining or jacket
Double-walled horizontal and vertical tanks
Double-walled bottoms of flat bottom tanks

STORED PRODUCTS:

Water-polluting liquids. The (possible) explosive vapor-air mixtures (also those that can be formed 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 T4. Example: petrol.

Special versions with detonation flame arresters type F 502 extend the range of application to explosion group IIB + H2.

INSTALLATION:

Leak detector (device category 2): zone 1, outdoors

Leak indicating unit: outside of Ex areas, inside a building or outdoors

HOUSING / IP RATE / TEMPERATURE RANGE:

VLXE .. A-Ex MV: stainless steel box / IP 66 / -40 °C .. +55 °C

LAE .. PMMV: stainless steel box / IP 66 / -40 °C .. +60 °C

PRESSURE RESISTANCE (maximum pressure in the inner tank):

VLXE .. A-Ex MV: 25 bar equipped with solenoid valve

VLXE .. A-EX MV mit ZD: 90 bar equipped with solenoid valve with additional pressure switch ZD

PNEUMATIC CONNECTIONS:

CF8/6: compression ferrule for copper (CU) pipe 8/6x1mm or polyamide (PA) hose 8/6x1mm !with plastic pipes observe required pressure resistance!
