Anyone can call their inverter an HVAC drive, but the ACH550 has been developed specifically for HVAC systems using ABB’s experience of over thirty years in the industry.  With more than 500,000 drives for HVAC installed globally, these highly reliable drives with built-in BACnet easily integrate into building management systems.

Installing ACH550 makes maintaining a building’s comfort zone easy, quick and energy efficient. The drives control the speed of pump, fan and compressor motors used in air handling units, cooling towers, chillers and other heating, ventilation and air conditioning (HVAC) applications. They help reduce the HVAC system’s energy consumption by up to 70 percent, and quite often have payback times of less than a year.

Integrated HVAC specific functions

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 swinging choke cuts harmonics emissions by up to 25 percent.

Reduced running and service costs

One big benefit of using the ABB ACH550 drives for HVAC applications is the energy saving opportunity over fixed speed motors or conventional flow control methods. Rather than have an electric motor running continuously at full speed, an AC drive allows the user to smoothly vary the motor speed, depending on the demand.  In addition to reducing energy usage, systems are quieter, control is improved and maintenance and service costs are reduced.

Interactive maintenance assistant means maintenance scheduling no longer requires guesswork.  The drive alerts you when maintenance is required based on your individual requirements.  Should a fault occur, the diagnostic assistant displays possible causes and potential solutions in plain language, and the fault logger is useful in tracking down drive failures. It records both time and date, and also takes a snapshot of seven diagnostic values, like motor speed and output current.
