Scully Tanker Grounding

Scully Tanker Grounding Systems mitigate the high risk of static build-up caused by friction between liquid and materials when loading flammable liquids.

These systems are essential in industries such as petroleum, chemical manufacturing, and transportation, where the handling of volatile liquids poses a fire or explosion hazard due to static electricity.

Scully Tanker Grounding
Features and benefits

Scully design and manufacture products that are the industry standard for hazardous, as well as flammable liquid handling. Originally designed for the petroleum market, Scully’s range of tanker grounding equipment is suitable for all flammable liquid products, including fuels, chemicals and spirits. In addition, here are some of the other features and benefits of the Scully ST–47C Groundhog Earthing System.

Provides non-permissive signal if proper earth is not present on a tanker. Operators can use this to control pumps and valves, allowing loading only when properly earthed.
It immediately shuts down the loading operation if proper static earthing is lost during the loading process.
Self-proving. therefore it continuously monitors the grounding condition throughout operation.
Users can employ it in conjunction with the Scully overfill monitoring system, therefore achieving complete tanker monitoring and loading control.
Clear red/green indicator lights provide visual proof of monitoring, as well as earth grounding.
SIL and ATEX approved for use in explosive atmospheres.
Operation temperature between -40° to + 60° C for extreme climate conditions.
