Tank Protection Systems

Scully systems are the number one choice worldwide for overfill prevention, grounding, and vehicle identification safety at bottom- and top-loading terminals

• Control fills and eliminate spills of petroleum and liquid chemicals into tank trucks and rail tank cars
• Capable of monitoring tank trucks with up to eight compartments when equipped with two-wire sensors or 15 compartments when equipped with five-wire sensors
• Superior system compatibility and performance when connected to tank trucks or rail tank cars outfitted with Scully sensors

The leader in Dynamic Self-Checking® overfill protection, grounding verification, and vehicle identification systems for bottom and top loading petroleum and chemical tank vehicles

Scully offers complete tank trailer/road tanker safety and information systems to prevent overfills, detect retained product, ensure your vehicle is at the same ground potential as the loading rack, and verify identification information.

• SAFETY: Only Scully systems offer Dynacheck® automatic and continuous self-checking, and the longest running safety record in the industry. Protect your people and your operations with the safest tank vehicle loading safety systems available.

• RELIABILITY: Scully products out-perform and out-last every other system on the market. It’s why we are the only company to offer a 5-year warranty on our overfill prevention sensors.

• COMPATIBILITY: Only Scully transportation equipment is 100% compatible with Scully Loading Rack Control Units. Why risk using another system that may not be fully compatible?

Protect your fueling operations with a complete line of Scully Liquid Safety Systems

• No operator on top of the vehicle ensures reduced liabilities and lower insurance costs
• Hatch remains closed, eliminating potential environmental and safety hazards
• Replaces older mechanical jet level sensors or floats that can fail at any point with no detection
• Dynacheck® Self-Checking circuitry means your Scully overfill prevention system checks itself 30 times per second to prevent human error, and if any sensor or component failure is detected, it automatically shuts down the operation
• One connection does it all—overfill protection, static grounding, and Dead Man Control.
• An Audio Interface Module with alarm is available for applications such as U.S. Navy Refueler and Defueler operations where an audio alert is required

In some applications, a Scully IntelliCheck® onboard control unit is used to control functions such as advanced interface modules, and bottom loading or defueling shutdown controls. Vehicles can be outfitted with an independent dual level system (high & high/high). The high-level sensor is controlled at the fill stand by a Scully control unit. The high/high sensor can be installed as a secondary shut down method controlling the vehicle’s bottom loading valves. If the valve or pump fails to shut down fuel flow at the fill stand, the secondary vehicle system will take over and shut down the vehicle’s bottom loading valve. The U.S. Air Force has standardized on this system.

Vehicle Identification Systems, which communicate via the overfill system plug to the control unit at the fill stand, can also be used to prevent mixing of different fuel grades.

Scully aviation systems have been standard equipment on U.S. Navy refuelers and Air Force R-11 refuelers for many years and are also in use in the commercial aviation market.
