Every hatch and valve on the tanker under control
In fuel and chemical transport a lock has to be suitable for explosive atmospheres. Locktech's ATEX-certified locks secure filling hatches and discharge valves, and secondary locks linked to the main lock let you manage every opening on the tanker together.
What happens in the field
- A tanker has not one but several openings: filling hatches, discharge valves, the fuel tank.
- Unauthorised discharge on the road is only noticed at delivery, when product is missing.
- Ordinary electronics cannot be used in an explosive atmosphere.
