A Rich History of Innovation Enduring the Ages in Heat Processing Technology

AGA-1941-3-Colored-inThe Selas name and products have a rich history in the importance of heat processing spanning from the turn of the 20th century through today. For over a century, Selas has been known as a pioneer and leader in heat and combustion technology. The products, technology and name have endured while playing an important role in the ability of industry to harness and control combustion creating industrial burners and processes which fueled the nations growth.

Demo1944The Selas heritage began with gas street lights in 19th century Germany. From there, Selas engineers began to explore other combustion needs and to develop new gas mixing products. Industrial process heating using premix burners, was pioneered by, and originally known as, the “Selas System”. In the early 1900’s “city gas” was available to use but pressures and heating values by cubic foot on gas varied and were often too weak for industrial burners. The automatic premixing of gas and air in a defined ratio and under a uniform pressure was achieved by the development of the Selas Combustion Controller.

The company expanded throughout the world and in 1930 sold its first radiant burner, followed later by heat processing kilns and furnaces.

The acquisition of the Pyronics and Ray Burner brand products has expanded the Selas combustion product line with additional combustion products also rich in history. The Maxsys product line is the exciting acquisition of products to help optimize fuel consumption while applying heat technology. More recently, Selas added the Red-Ray infrared burner line and the ERB Ensign ribbon burner product line. Webster Combustion, a manufacturer of boiler burners for commercial and industrial applications, was acquired in 2014.

Butt-Welding-Furn-6-1966The Selas name originated with the Selas company in 1896. Throughout many years, products have been added and dropped, divisions formed and divested and corporate ownership has changed. The constant through all of this change is the Selas name and foundation of products. Products with time proven engineering and manufacturing to endure the ages.
