Physics first
We say what we have measured, and we label what we have only modeled.
About
Intrnls is a design and engineering company in Wales, Wisconsin.
We develop new evaporative media for cooling towers and evaporative air coolers, and we test it at our own bench. We also take on hard industrial problems where the shape of a part does the work.
Why we started
We started Intrnls to get good engineering out of the lab and into real plants.
We kept seeing good engineering end at a report. The physics worked and the prototype worked, but nobody was set up to carry it into a plant. So we built a company around the whole path: material, design, pilot, product.
We think shape is the most under-used tool in industry. Geometry can hold a film of water, move heat and carry a load. Evaporative media for cooling towers and air coolers is where we are putting that to work now.
How we work
Three rules we work by.
All the way to the plant
We stay on through the pilot and into the product.
Big problems
We take on work that changes how a plant is built or run.
People
The engineers who designed it work on your project.
You work with them directly, from the first call to the plant.
