Transport Passive Systems

Model LDS100A

*Electronically controlled sensing detects leaks in piping and hose assemblies *Automatic "out of product" shut off *Easy installation with modular components *DCE certified *5 minute auto shut down "Query" feature available. Includes tractor engine kill capability

System Overview
An automatic leak detection and shut down system designed by professional engineers specifically for LPG and Anhydrous Ammonia bulk transfer. Intrinsically safe unit continually monitors the offloading process for "rate of change" parameters signifying broken or damaged hoses, fittings and piping. A leak is instantly detected and stopped by the closure of the tank internal valve(s). The truck's engine can also be stopped and PTO disengaged if desired. This system automatically activates at the end of each load. This ensures that the system is fully operational and helps reduce the possibility of a damaged cargo pump due to product run out. This unit also "fails safe" and closes the internal valve with a loss of power or the release of the trailer parking brakes.

An optional "Attendance Timer" is available. This query feature stops the offloading process if the operator fails to press the "GO" button within a five minute window. A 30 second warning will sound followed by delivery shut down. This feature helps ensure operator attendance during the loading/offloading process.

System Overview
A fully automatic leak detection system for propane and anhydrous ammonia transports. This system has been designed & tested by Design Certified Engineers to meet the compliance requirements of US HM225A and Canadian B620 regulations. The low powered intrinsically safe control unit continually monitors all piping and hose assemblies during the offloading or loading process. A failed pipe, or hose separation will cause the tank's internal valve to close instantly and sound an audible air-horn alarm. A simple "reset" button returns the unit to the monitoring state.

The BASE SafeGuard passive system incorporates a functional "test" button as a way to determine the unit's readiness. This sytem is easy to install and requires no calibration, adjustment, or auxiliary controls. It turns on automatically by opening the internal valve and turns off when the valve is closed. Drivers do not have to activate it or monitor it. Options include multi-pipe or trailer sensors, automatic truck engine or PTO shutdown, and self contained "Power Pack" for system operation with no truck power supply.
