Thermal pressure relief devices (TPRDs) are required for composite storage vessels and any other systems where the ability of a component to contain pressure may be compromised by heat or fire. A TPRD is intended to vent the contents before a …

- Leader manufacturer of components for the H2 mobility - H2 storage system and fuel cell system components - Different operating pressures 350 bar and 700 bar. - Products for liquid hydrogen under development. - Products approved worldwide and used on all types of vehicles (forklifts, cars, trucks, buses, trains, planes, off road vehicles)

This thermal pressure relief device (TPRD) is designed to clear up tanks and vessels when overheating. A glass ampoule is destroyed when the reaction temperature (typically 110° C) is reached, thus releasing the hydrogen from the tank out through a safety vent in a very short time.

This thermal pressure relief device (TPRD) was developed to relieve tanks and containers in case of overheating. When the reaction temperature is reached, a glass ampoule is destroyed so that the hydrogen can escape from the tank via a safety vent. The special feature of this TPRD is its rotatable installation option. /

• In the event of a fire, thermally activated pressure relief device (TPRD) provides a controlled release of the CGH 2 from a high pressure storage container before its walls are weakened by high temperatures leading to a hazardous rupture. • TPRDs vent the entire contents of the container rapidly. They do not reseal or allow re-

2021年10月22日 · This study aims at the understanding of thermal behaviour of a tank-TPRD system in a fire and the development of a methodology to optimise the TPRD diameter to prevent both tank rupture in a fire and allow parking of HPVs in confined spaces like garages and maintenance shops without risk of civil structure destruction by PPP.

2023年9月15日 · Parametric CFD simulations studied effect of different TPRD diameter, release direction, vehicle distance from obstacles, ceiling height, influence of carpark ventilation on hydrogen hazards. Hazards of unignited releases were associated with the lower flammability limit of hydrogen-air clouds.

If outside factors push your H2 containment system toward critical temperatures, our PTEC TPRD (Thermal Pressure Relief Device) “breaks” the heat wave. We have engineered the device’s glass ampoule to burst when it’s time to safely vent the pressure. Manage your hydrogen-fueled operations with peace of mind using PTEC TPRDs.
