Trust Roessler Equipment Company with your ABB Variable Frequency Drives.

The ABB ACH550 is a variable frequency AC drive (VFD) designed specifically for the HVAC market that achieves the ultimate in flexible motor control performance.

With drives ranging from 1 to 550 HP, the ACH550 series features an ‘intuitively obvious’ multi-lingual, graphic display panel that also provides an assistant to aid users in start-up. The control panel can be mounted on the cover of the drive, or remotely, and can upload, store, and download parameters.

The ACH550 comes equipped with an extensive library of preprogrammed HVAC application macros that, at the touch of a button, allow rapid configuration of inputs, outputs, and parameters for specific HVAC applications to maximize convenience and minimize start-up time.
