About Us

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.
In our 30 years on the market, we have learned what you, our customers, want and need. We always strive to meet you halfway, which is why LAC has come to specialize in custom production, which now forms over 60 % of our work. With our products, we help you to increase your production capacity, save on energy costs, reduce boiler emissions, and maintain your equipment in the best condition possible for the longest time possible. And indeed, our maintenance services and expert consulting are something that Mr. Ledl and Mr. Crhák themselves appreciate. You see, they want to be sure that we supply high-quality products that will serve you long and well. They want to always be proud of how we do our work.
LAC, s.r.o. is a purely Czech firm that has grown its way from a 10x10 m garage up to manufacturing, storage, and administrative spaces with a total area of 25,000 m2. Since our founding in 1992, we have developed and produced almost 20,000 furnaces and dryers and over 50,000 different shapes for refractory castable shapes.
We have over fifty lines of standard furnaces and dryers in our assortment, and we develop six custom projects per month. And to give you an idea of our growth — in 2000 we had 114 employees and a turnover of 85 million crowns, while today we have 230 employees and a turnover rising towards 324 million.
