The option ExReady can be used with the completely closed T15 in explosion-proof ranges of the zones 1 and 2. By an expandable pressure monitor module and an external control unit the  housing of the T15 is rinsed permanently and automatically. Since the pressure monitor has the same boreholes as the T15, neither the standardised support arm system nor the housing of the T15 must be changed.

The rinsing masses of gas necessary for the rinsing procedure and the enterprise are readjusted by the controller automatically and ensure a troublefree function.
