Danfoss' motor-controls division will supply HVAC maker Trane with brand-labeled variable-frequency drives for its commercial air-conditioning systems, officials from both companies recently announced.

Under the long-term renewable contract, Danfoss will continue to manufacture Trane Co.'s TR1 Series variable-frequency drives for HVAC uses. Additionally, Trane and Danfoss will work together on manufacturing, sales and product development to meet demand for HVAC drives.

"This agreement will allow us to supply customers with Trane-branded HVAC drives," said Ronnie Seay, strategic supply manager for Trane. "Because it involves both our production and sales operations, it is an exceptional collaboration."

"This is a strategic partnership that has potential to affect the direction of the HVAC drives market," said Bill Mudge, HVAC vice president of sales and marketing for Danfoss North America Motion Controls. "Over the next two decades, demand for HVAC drives will increase dramatically."
