MUNSTER — Tec Air Inc., a designer and manufacturer of plastic air movement components and systems, announced plans today to relocate its Willow Springs, Ill. headquarters to Munster, creating up to 258 new jobs by 2016.

The 48-year-old company will lease, equip and relocate its current Illinois headquarters into a 128,000 square-foot facility located in the Lake Business Center at 9200 Calumet Ave. in Munster. Tec Air will initially invest approximately $7 million dollars in new equipment and building improvements in connection with the move. In addition to the new investment, Tec Air will also transfer almost $8 million of assets from its Illinois facility to the new location, bringing the company’s investment in Indiana to approximately $15 million.

The expansion, which will be complete next spring, will house corporate offices, engineering labs, manufacturing, quality labs, warehousing and distribution. Tec Air’s investment in the new Indiana facility will include new injection molding and assembly equipment, such as process cooling, material handling, molding machines, robotics and R&D test equipment.
