Carrier Corporation (Farmington, CT, U.S.) and ABB Inc. (New Berlin, WI, U.S.) announced that they have signed a corporate supply agreement. Although just announced, the agreement became effective in May of this year.
ABB's Automation Technologies, Low-Voltage Drives division is providing a new line of variable frequency drives, the ACH550 series, as part of the agreement. Carrier is utilizing the drives in its Weather Series Rooftops and Aero air-handling product lines.
"The drives met our strict performance criteria and our quality assurance requirements, which were key to making this agreement happen," said Bruce Burdon, director of Product Management and Marketing for Carrier's North America Commercial Division. "The drives already are being utilized in our commercial products, and the customer response has been extremely positive," he said.
"It is an honor to be part of this arrangement -- and it marries together the technology of two of the strongest suppliers to the HVAC industry," said Jeff Miller, HVAC sales manager for ABB Inc., Low-Voltage Drives. "End users gain the most, because the features and ease-of-use benefits make equipment installation and start up faster than ever," he said.
According to ABB, the ACH550 drives that Carrier now offers features a user-friendly control keypad, modeled after a cell-phone design and utilizes full language (rather than codes). New-to-market features of the ACH550 include maintenance, diagnostics, and programming assistants, along with help screens and a help key.
ABB's patent-pending Swinging Choke design, built into the drive, is also said to reduce harmonics at both full and partial loads, for a total harmonic reduction of up to 30 percent when compared to traditional reactor designs, and up to 64 percent, compared to drives with no reactors (estimates are based on a power system impedance of 1 percent).
