Warehouse Ventilation Fan Panel

Our company was sub-contracted to build a panel for driving 14 ventilation fans each rated 5.5kW at a local manufacturing company warehouse. Each fan was driven by a variable speed drive.

Apart from the variable speed drives, the panel consisted of a programmable controller together with a touch screen HMI for setting of fan speeds and operating schedule. In case of a fire event, the system is hard wired to bypass all control and drive the fans at full speed.
