German firm buys Tri-Dim Filter Corporation

Posted on Tuesday, September 11, 2018 at 8:45 am

The sixth-largest employer in Louisa County has been acquired by a large German-based firm.

Tri-Dim Filter Corporation had been a family-operated business in the county since it opened its first manufacturing plant in the Louisa Industrial Air Park in 1982. Though it was acquired in August by Mann + Hummel, the Tri-Dim name will remain at the plant on Industrial Drive.

While Tri-Dim has $130 million in annual sales, its new parent company has $4 billion. Tri-Dim employs 820 people, including just over 200 in Louisa. Mann + Hummel has more than 21,000 workers.

“It’s not luck, it’s hard work and dedication that drove us to where we are today,” Hakan Ekberg, a Mann + Hummel vice-president, told a crowd of Tri-Dim workers at a merger celebration at the Louisa plant on Aug. 31.

A key advantage in selling to Mann + Hummel is the fact the parent company specializes in consumer automotive filters, while Tri-Dim makes filters for heat and ventilation at industrial and large public facilities, according to Duane Colwell, Tri-Dim’s marketing director.

Louisa’s workers are likely to see few changes, he said, which might not have been the case if Tri-Dim had been acquired by a direct competitor.
