Don Winter, vice president of marketing for McQuay, noted that the new Daikin McQuay brand represents the integration of Daikin technology and design into McQuay commercial products distributed in North America and worldwide. McQuay is a member of the Daikin group.
The new AWS line of air-cooled screw chillers range from 175 to 510 tons. The new brand features improved efficiency and reliability and quiet operation, said Winter. Standard models use R-134a refrigerant and meet ASHRAE 90.1 standards, he added.
“The AWS air-cooled screw chiller has been redesigned from the bottom up,” said Winter. “It utilizes a new efficient and reliable compressor, new quieter fans, and new MicroTech® III controls. Daikin engineers were involved in the design and Daikin fans are being used to make the AWS the quietest air cooled chiller in the marketplace.”
Final performance of the high-efficiency models is yet to be finalized, “but will be industry leading,” stated Winter. Orders for the new product can be placed in the second-quarter of this year, with shipment expected in the third quarter.
“Although we have introduced a new product and a new brand, our company name remains as McQuay International, a member of Daikin group,” said Winter. “Overall, the Daikin McQuay name will be used on products that incorporate Daikin technology or design expertise.”
MORE THRILLS AND CHILL(ER)SOther manufacturers that introduced new chiller developments at the expo include:
