Our History

Slide number 02 of / 06


The founder of Federal, Louis Loeffler Sr., and his brother came to Oklahoma City in 1918 to establish the Federal Steam Specialties Company on invitation of a few architects and contractors they worked with. The 1920s were booming times as the young state was building county courthouses, governmental buildings, and factories. The 1930s brought the Great Depression, which forced many companies out of business and put a strain on Federal. Louis Loeffler Sr. passed away in 1941.

Our History

During the 40s, two of the founder’s sons, Louis Jr. and Norman kept the doors open during the war. With the war effort commanding most steel products, the company diversified to sell whatever it could. After the war, the company greatly expanded in product depth and customer base, and built a larger staff. The brothers shaped the company to the foundation it is today from the 1950s through the 1970s.

The third Loeffler generation was represented by Alan Loeffler, son of Louis Jr. Alan led the company starting in the 80s, when we opened the Tulsa office and began offering additional control products to our commercial and industrial customers. Through a strategic planning process in the early 2000s, the company refined its focus on hydronic, steam, and combustion equipment and controls.

The fourth Loeffler generation was headed by Dan Loeffler, son of Alan starting in 2008. Dan came from a strong legal background, and in his 10 years of leadership he strengthened the company in its financial, accounting, and personnel areas. He also encouraged the company to use the internet to bring an online catalog and ordering capability to its customers. Additionally, Dan helped establish Federal Services LLC as a subsidiary. This specialized service group has brought industrial combustion control systems to a new level in the mid-stream gas industry and other industrial fields. His untimely death on April 2nd, 2018 left a legacy that we carry on today.
