Founded way back in 1912 as the “Replaceable Heating Elements” company in New York, Lindberg/MPH was named after the owner’s patented, replaceable heating elements for research heating applications.

In 1924, the company was renamed Hevi-Duty Electric Company and moved to Milwaukee, Wis. It wasn’t until 1963 that Lindberg was added to the name after the acquisition of Lindberg Engineering, leading to the renaming of the company to Lindberg/Hevi-Duty. The MPH brand was combined with Lindberg in 2005 under the ownership of Thermal Product Solutions LLC. 

Today, more than 100 years since its founding, the Riverside, Mich.-based company manufactures a range of industrial furnaces that are capable of processes such as aging, annealing, carburizing, drying, sintering and tempering. In fact, Lindberg/MPH has more than 75,000 industrial furnace installations worldwide. This equipment is backed by a full range of customer-support services and an extensive replacement-parts inventory.

This associate member’s range of furnaces includes pit, box, IQ and belt-type for the ferrous and nonferrous markets. Furnace models are available with exothermic, dissociated ammonia or nitrogen atmosphere systems. Lindberg/MPH also manufactures melting and holding furnaces for nonferrous alloys. The company’s customers cover a range of industries, including aerospace, automotive, military, mining, heavy equipment and medical.

Lindberg/MPH prides itself on designing its industrial furnace systems to use the most energy-efficient components. Most of its equipment is built to utilize low-NO₂ combustion systems and afterburners or converters to reduce harmful emissions.

The company does much more than design and manufacture furnaces. Lindberg/MPH’s factory-trained experts can help diagnose issues, order parts, install equipment and upgrades, and perform annual maintenance and testing. Services include: calibrations, preventive maintenance, SCADA systems and control upgrades, temperature uniformity surveys (TUS), training classes, and turnkey installation and commissioning. Whatever the case may be, Lindberg/MPH tailors its services to customer needs and equipment because there are no one-size-fits-all solutions.

After 106 years, the company is still investing and evolving. In early 2017, Lindberg/MPH invested in the future by purchasing an Emrak press brake and hydraulic swing beam shear to maximize its production capabilities. The company also added an Amada computer-controlled hydraulic punch to its Riverside facility later in the year.

As for the future, Lindberg/MPH will be focused on continued growth of custom-engineered equipment along with increased sales in standard products to all industries it serves. The company plans to be around for at least another century.

Lindberg/MPH is owned by Thermal Product Solutions LLC (TPS), a leading American manufacturer of custom industrial ovens used for heat treating, finishing, drying, curing, manufacturing automation and process control. TPS is a global leader in thermal-processing products and test solutions with brands including Baker Furnace, Blue M, Gruenberg, Tenney, Lunaire and Wisconsin Oven.
