Intrnls Inc.

Intrnls, Inc. designs and manufactures engineered internals for equipment that moves heat and mass between air and water: cooling tower fill, air-water contactors, and concentrators.

We use advanced manufacturing developed in Wisconsin to build geometries that conventional forming cannot produce. That lets us work on the structure of the equipment rather than the chemistry running through it, and it lets us tune a part to a specific duty instead of picking the nearest item in a catalog.

We work with industrial and utility customers in evaporative cooling, data center cooling, and carbon capture, from bench testing through pilot scale. We build in Wales, Wisconsin, we are backed by Wisconsin investors, and we work alongside universities and industry across the region.
