Dynacheck®
Revolutionary Self-Checking Protection
Continuous Fail-Safe Monitoring for Peace of Mind
Among Scully’s many patented innovations, our Ventalarm Signal® and Dynacheck® safety solutions revolutionized the liquid handling industry. Introduced in 1935, Ventalarm Signal® protected oil delivery drivers from dangerous tank overfills and spills. Twenty years later, Scully designed and patented the world’s first dynamic self-checking, fail-safe circuitry.
Dynacheck®
Scully’s Dynacheck® technology was considered to be so advanced and safe, that it was licensed for specialized flame safeguard and nuclear radiation detection controls and used in refineries and laboratories. Transferring hazardous liquids is a dangerous business and a secondary emergency shutdown system is the last line of defense to prevent catastrophe. Since its inception, Dynacheck® has been incorporated into every Scully overfill prevention system.
All system components—including sensors, wiring, connections, and the internal electronics circuitry—are monitored 30 times per second. Dynacheck® automatically and continuously tests for wet sensors, system faults, and lack of grounding. No manual testing is required. If a wet sensor or fault is detected, the system instantly alerts you and shuts off product flow.
Our passion for safety and reliability extends to every liquid handling solution we design and manufacture. Our in-house design, engineering, and manufacturing teams never settle for “safe enough” and neither should you. As the originator of heating oil delivery safety systems, Scully has the technical know-how and experience to help keep your operations running smoothly and safely.
