KIT SOBREPRESIÓN<br />
The system of pressurisation of staircases, escape routes or of<br />
<strong>co</strong>nfinement enables to <strong>co</strong>ntrol the airflow automatically and<br />
to maintain a differential pressure of 50 Pa in a single stage,<br />
ac<strong>co</strong>rding to standard UNE EN 12101-6-2006.<br />
Stairwell kit sobrepresión<br />
Differential pressure transmission set (TPDA), frequency <strong>co</strong>nverter (RFM) and outlet units<br />
(CJHCH or CJBD) , for the pressurisation of the stairwells and escape routes.<br />
Kit Sobrepresión with reserve fan<br />
Differential pressure set which in<strong>co</strong>rporates a system of automatic switching to keep the<br />
overpressure in the case of a stop by the main fan. The set <strong>co</strong>nsists of a probe of differential<br />
pressure TPDA, an automatic switching board ARM (varier, sine filter and <strong>co</strong>ntrol manoeuvre)<br />
and TWIN air outlet units.<br />
