Where splash loading is not acceptable, a telescopic drop tube is used with a bottom contact switch, ensuring that the drop tube is permanently in touch with the bottom of the tanker being loaded.
Our telescopic drop tubes can be either manually or pneumatically operated.
Manually operated telescopic drop tubes are robust and have a short installation.
The following situations may require the use of a telescopic drop tube:
Internal friction in flowing products can cause electrostatic charge. This physical effect can lead to sparking which is mandatory to be avoided, especially when combustible or explosive fluids are loaded. Spark prevention can be achieved most efficiently by creating bottom contact with a telescopic drop tube.
Bottom contact with a telescopic drop tube is recommended for loading of foaming products.
For loading applications with height restrictions (e.g. by a roof) a telescopic drop tube is the ideal solution compared with a long and rigid drop tube.
