Ledl and Crhák. Two foundrymen—friends who built their first furnaces for enjoyment and for their friends. Today, they own a company employing 230 people that ships furnaces and dryers all around the world and ships refractory castable shapes all around Europe.

LAC is more than just standard industrial furnaces and dryers. We meet your custom demands that others would refuse to even handle. We don’t simply sell machines. We want to stop by in a few months or years and make sure that everything is running like clockwork. And if it’s not, our servicing team will handle all repairs and reconstruction.
