That drove us towards to our new more heat … a real double whammy,” Sean chimed in.

Whether the cooling challenge is WWII landing craft, an sus today, that same engine will require signi? cantly more heat exchange, essentially resulting in bigger cooling units. “This is EPA Tier 4 [and beyond] engine, or stacks of battery banks on an area of change for use where we are investing in the product an electric vessel, Sean Fernstrum keeps his company focused to innovate so that we are still cost effective,” said Sean. As the on the mission at hand: “Our strength is heat exchange. Whether it’s cooling or coolers are getting larger, one option is to stack them. Two de- cades ago the company only did a few ‘stacked’ units per year, heating, it is heat exchange. That’s our core strength. We’re today it seems like every order is going to the stack tube to get serving that with a number of different product lines now, and we can bring those together and provide a packaged solution.” them to ? t on the vessel.
