ABB VFDs
ABB manufactures their model ACH550 drive specifically for the HVAC industry. Sizes range from 1/2 to 1000hp.

The drive is programmed with several HVAC applications, including supply and return fans, cooling tower fans, booster pumps and condensers. The intelligence within the HVAC control panel means that the user is given direct and understandable instructions in clear text at all times.

Harmonics and RFI emissions are major concerns within many HVAC installations. The ABB drive for HVAC fulfils demanding requirements for electromagnetic compatibility. A patent pending, swinging DC choke cuts harmonics emissions by up to 25 %.
