Centralised Vacuum systems are used to provide point of vacuum throughout a test laboratory or facility, and to provide a certain vacuum within the system to allow correct operation of the equipment connected.
Installing a central vacuum system is very advantageous especially from the standpoint of energy savings because the pumps will only switch on when there is a demand on the system.
Systems can be supplied in either a simplex, duplex or triplex rotary vane vacuum pump configuration with connection directly or indirectly to a horizontal or vertical mounted mild steel reservoir depending on the floor space available.
Automatic vacuum control is achieved by a vacuum switch with two adjustable setpoints to start and stop the pump at the high and low points demanded by the application. An electrical panel with PLC to start and run the pump in manual or automatic mode complete with cutout switch, hour counter and start and stop switch.
The PLC also controls the automatic wear on the pumps, so that each pump is selected as the ‘primary' pump in turn on every cycle. Each pump can also be isolated separately via a ball valve for emergency or routine maintenance without interruption to the systems ability to run.
Applied Vacuum Engineering can provide a complete package including installation and commissioning.
