Paybacks range from six months to two years – Returning Your Initial Investment!

Exo Gas and Steam Co-Generators are available in sizes from 4,000 to 100,000 SCFH of exothermic gas, producing 390 to 9,780 lb/hr of steam. Wellman also offers a variety of Atmosphere Flow Panels and Gas Analysis Equipment for use in distributing, monitoring and controlling the various atmosphere gases that are used in your process.

Custom Engineered Systems

We Design, Build and Install Heat Processing Systems Worldwide

Where Tradition Meets Innovation . . . . .

Wellman Furnaces, Inc. brings innovation together with the ability to engineer, design and build the answer to your heat processing problem. We offer our customers years of experience in the custom engineering of fuel fired and electrically heated furnaces and heat processing systems. Also, we are able to offer engineering services for the evaluation of equipment alternatives, process engineering and thermal analysis.

Wellman's roots can be traced to the General Electric Company's Industrial Heating Department which moved its operation from Schenectady, New York, to Shelbyville, Indiana, in 1955. In 1979, Wellman plc, a British company, purchased the Shelbyville operations from GE, renamed it Wellman Furnaces Inc. and retained all personnel for the design, manufacture and marketing of Industrial Heating Equipment. In 1988, the business was sold to the managers of the Shelbyville facility, who ran the Furnace company along with seven other purchased Wellman companies until 2003.

In 2003, Wellman Furnaces, Inc.'s ownership changed to its current status under Precious Technology Group, LLC. Precious Technology Group has transitioned Wellman Furnaces, Inc. into a versatile and capable entity able to carry on the responsibility entrusted to us by our customers.

Wellman serves a variety of customers, including users and E&C's, in a broad range of industries. We have worked closely with many US firms and have had extensive international experience dealing with customers in places such as Canada, China, Europe, Egypt, India, Japan, Mexico, Saudi Arabia, South Korea, and Thailand.

Industrial Furnaces

Wellman Furnaces offers it customers years of experience in the custom engineering of fuel fired and electrically heated furnaces systems.

Wellman utilizes "Concept to Completion" expertise to meet your heat processing requirements. Our team begins by carefully analyzing our application. From here, we engineer a practical concept using proven components. The equipment is then manufactured in our Fairland, Indiana, factory by experienced furnace builders. Finally our seasoned field service engineers complete the project by installing and starting up the equipment.

Roller Hearth

Wellman's broad experience in building Roller Hearth Furnaces includes direct-fired and atmosphere furnaces for temperatures to 2100°F (1150°C). Fuel-fired or electrically heated designs are available.

These furnaces are ideal for lamination annealing, tube annealing and many other processes. For example, a successful Roller Heath line was provided for reheating molybdenum and tungsten sheets for rolling. It features a unique pulse-fired combustion system.

Mesh Belt

We offer a wide line of hump type and straight through mesh belt furnaces and ovens for continuous blackening, brazing, annealing and sintering of light parts or assemblies in controlled atmospheres.

Belt widths range from 12" to 92" for processing temperatures up to 2100°F (1150°C). Silicon carbide, ribbon or tubular heating elements are available along with direct heated or muffle type designs. Water-jacketed coolers are shipped as complete sections. Air jet coolers can be provided for final cooling.

Rotary Hearth

For reheating in a controlled atmosphere before subsequent forging operations. Also used for hardening, stress relieving and annealing.

Wellman Rotary Hearth Furnaces are useful for a number of processes including forging and forming, hardening, tempering, stress relieving and annealing. Units can be direct-fired or engineered for a controlled atmosphere with your choice of gas or electric heating. Temperature range to 2300°F (1260°C).

Precise indexing of the rotary hearth on Wellman designs is accomplished through a rack and pinion system and variable speed drive. Manipulators or custom designed load/unload equipment can be supplied.

Cast Link Belt

Used for continuous hardening, tempering and annealing of irregular and randomly spaced loads such as forgings, casting and fasteners.

Bell Type

Used for annealing, brazing, stress relieving, oxide reduction and sintering. Vacuum or controlled atmospheres are available.

Car Bottom & Tip-Up

Car Bottom Furnaces can be provided for annealing, normalizing and stress relieving bars, tubes, forgings, large weldments and castings and can be gas fired or electrically heated with either guillotine or bulk head doors. Sand or pneumatically operated mechanical car seals are available.

Tip-Up Furnaces are used where better atmosphere control and temperature uniformity are necessary. Alternate load/unload methods are available.

Special Purpose

Whether your need is for continuous or batch process, small or large load, long or short cycle, fixed or variable process, electric or fuel-fired, Wellman has the expertise to engineer, design and build it. Our record proves it. We have provided custom heat processing solutions for tough applications all over the world.
