Broadway 45 HP Electric Starter Panel W/ VFD - Accessory
As the cost of electricity increases variable frequency drives (VFDs) are increasing in popularity within the carwash industry. Adding a VFD to an electric motor application in a car wash setting is a cost-efficient and reliable option. Often times the addition of a VFD to a car was dryer system can provide a return on investment within 14 months in electrical energy savings. A variable frequency drive is an electronic device that changes the speed of a motor's rotation by changing the frequency of the power being fed to the motor. The relationship between a motor's speed and the frequency of the power fed to the motor is linear. For instance a motor that is designed to turn at 1800 rpm's when connected to a standard 60hz power supply will run at 900 rpm when connected to a VFD supplying 30hs of power.
