Adding a VFD can help in improving efficiency on functions within the boiler room. Older blower motor designs operated at fixed speeds regardless of the demand that was actually needed for the output of the system. A variable frequency drive or variable speed drive used in a combustion system can match the motor's speed to a lower rate while still satisfying the airflow requirements. Likewise, the use of a VFD on a deaerator or feed system can aid in giving the pumps more versatility, as well as a protection factor for the pumps. Find out more at www.powermechanical.com/conta...
