Hospital central vacuum system
Induvac hospital vacuum units are CE CERTIFIED and are provided in different shapes according to different requirements. Therefore they can be vertical or horizon-tal. They consist of three pumps, a reservoir complete with a condense exhaust system and two bactericidal filters (UNI EN 7396-1:2007 Paragraphs 5.7.1). After the first man-ual start up, the unit runs automatically, maintaining the required vacuum level in the reservoir. The unit is designed to meet the normal requirements of the user by operating a single pump. The units are set according to an experimental simultaneity coefficient accounted for in the calculation of the system capacity (UNI EN 7396-1:2007 Paragraph 5.7.2). When needed, the second pump starts running and doubles the capacity in order to re-adjust the system to the re-quired vacuum conditions. If even the second pump cannot meet the required vacuum, then the third pump starts working. (UNI EN 7396-1:2007 Paragraph 5.7.3). On each starting, the control board makes it possible to exchange pumps in order to get equal wearing for the three pumps. Running hours are shown on the display in the centre of the main control board. The third pump, called ―emergency pump‖, is driven electronically by the main board, but sup-plied by a separate emergency control board (UNI EN 7396-1:2007 Paragraph 5.7.5) . When needed, the emergency pump starts working even in case of control board fault or disconnection (UNI EN 7396-1:2007 Paragraphs 5.7.7). The by-pass system allows to carry out reservoir replacement and/or maintenance without stopping the unit

The third pump, called ―emergency pump‖, is driven electronically by the main board, but supplied by a separate emergency control board (UNI EN 7396-1:2007 punto 5.7.5 ) . When needed, the emergency pump starts working even in case of control board fault or disconnection (UNI EN 7396-1:2007 punti 5.7.4 ). The by-pass system allows to carry out reservoir replacement and/or maintenance without stopping the unit. (UNI EN 7396-1:2007 punti 5.7.7)
