The RWA complete solution for staircases<br />
RWA emergency <strong>power</strong> supply units enable the coordinated actuation and release of fresh and exhaust air openings equipped <strong>with</strong><br />
electrically operated drives. With the new THZ emergency <strong>power</strong> supply unit, <strong>GEZE</strong> is presenting a compact solution for reliable<br />
smoke dissipation in staircases. The new control unit permits connection of a complete smoke dissipation solution comprising at least<br />
two drives, one fresh air and one exhaust air opening. The THZ is great value for money thanks to its high performance capacity and<br />
installation advantages.<br />
