Description
The Lochinvar & A.O. Smith 100167885 Variable Frequency Drive is a commercial HVAC system used to control the speed of pumps and fans in their IB/IW 1500-200 boilers. It is operates based on fluctuation in the frequency of the current supplied to a motor while altering the motor rotation rate. This make it possible to regulate water or air flow to meet the systems requirement and minimize energy use. Advantages include better temperature regulation, lower energy consumption at part load due to slower motor speeds, less noise, and longer life of the equipment due to reduction in mechanical stresses caused by frequent starting and stopping.
