End Plug Thermal Pressure Relief Device (TPRD)
The End Plug TPRD (Thermal Pressure Relief Device) is designed to protect gas storage tanks in the event of a fire. It ensures rapid and spatially directed tank discharge at elevated temperatures, thereby preventing the tanks from bursting.
Technical Data and Specifications
Thanks to its optimized design, the End Plug TPRD meets individual customer requirements while complying with all relevant regulatory standards (UN/ECE R134, CSA/ANSI HPRD 1:21).
A minimum installation space of 100 mm is required for proper integration.
