The MBBR is controlled from the electrical control panel, which houses a plc and hmi control system.
The MBBR system consists of two blower motors (one duty and one standby) and one/two feed pumps. The blowers are connected to Eaton VSD’s within the electrical panel. The speed of the blowers can be controlled by adjustment of a potentiometer in the electrical panel.
The speed of the blowers will be optimised on commissioning and thereafter should not need further adjustment during normal operation.
