VTN Life Support Units

Life support units are designed for use in extremely dangerous circumstances where users are obliged to work, for instance, in inert confined spaces (Inert Entry) for catalyst work.

We can deliver a client-specific solution for you that is built onto a truck or another type of vehicle, as desired. For example, a BE trailer, container or delivery vehicle.

The unit is built in our own workshop and fitted with a primary and secondary breathing air facility in which the incoming breathing air is monitored in accordance with NEN EN 12021.

The custom-designed control panel consists of manually controlled high-quality valves and manometers and a completely digital dashboard in which the operator can add the names of the users to the session times.

The digital dashboard includes the personal flow meters that trigger alarms to warn the operator if aberrations are detected in the system.

All important parameters are stored digitally and can be used to make reports and analyses.

In addition, all optional accessories such as ATEX camera systems, communication systems, gas detection and temperature sensors are completely integrated into a single, uncluttered control panel.
