In 1988 Checker Machine began manufacturing a line of low-tension, direct- inject spiral steam ovens. Between 1988 and 2014 they manufactured more Spiral steam ovens than anyone else, and shipped them to four different continents. In 2015, Anderson Dahlen acquired the Checker spiral steam oven business with the idea of combining it with their own linear steamers and expanding the total product offering. Along with that purchase Anderson Dahlen added several key Checker design, sales and manufacturing people to their staff to assist them in their new endeavor. With these additions Anderson Dahlen has over 40 years of experience in spiral steam oven manufacturing, application analysis and installation.
