Chiller systems and heat pumps maker Multistack has purchased Desert Aire Corp. Terms were not disclosed.

Desert Aire is a Germantown, Wisconsin-based manufacturer of commercial HVAC construction and industrial humidity and climate-control systems.

Officials with Mutistack said Desert Aire would be run as a wholly owned subsidiary, with Multistack keeping its headquarters in Sparta, Wisconsin, and Desert Aire’s manufacturing, research and engineering offices staying in Germantown.

"We are thrilled to have Desert Aire join us as we design and produce the most energy efficient and advanced systems in the HVAC industry,” said Multistack CEO Charles Kenyon. “With both companies having industry-leading reputations as well as cultures that emphasize quality and customer support, this is a natural combination."

Keith Coursin, president of Desert Aire, said becoming a subsidiary of Multistack will be good for his company.

“Multistack's leadership and capabilities bring additional resources that will help us with our growth plans,” he said. “We feel by joining together we will each become a better company."
