Based in Cleveland, OH, Sentro Tech has been manufacturing high temperature furnaces since 1998. Our stellar technical support and 100% satisfaction guarantee complement the range of products we offer. Sentro Tech is a supplier to 18 industries—a number that grows as we innovate new technologies. We produce standard and custom heating elements made with corrosion-resistant materials. Finally, Sentro Tech devices also offer atmosphere and vacuum control capabilities.

The industries we serve include:

Heat Treating

Heating treatments involve changing the properties of materials such as glass or metal. Using heat, these materials can be hardened, softened, or modified in a variety of ways. Heating elements, such as furnaces, help to perform the processes of quenching, annealing, and tempering used in heat treating.


The mining industry retrieves metals, minerals, and other materials from within the earth. This also includes non-renewable resources such as petroleum or natural gas. Furnaces are used in the mining industry to smelt and cast metals after they have been retrieved.

New Materials Development

Research and development of new materials is aided by high temperature furnaces. The new materials industry experiments with materials composed of different elements and with different capabilities. Thermal testing with industrial furnaces is one way that this research is conducted in materials science.

Powder Metallurgy

Powder metallurgy uses blended powder to custom create solids, such as metal materials. This process is more cost effective than metal removal processes such as mining. Heat elements are used in the process of sintering, which is the final step in solidifying the powder.

University Laboratories

Heating elements are useful in research laboratories in areas such as chemistry. Lab furnaces often need specific control requirements and pressure ranges. Sentro Tech manufactures furnaces for student and professor research on university campuses. Our custom furnace capabilities can be tailored to the needs of research labs with different sizes and requirements.

Quality Control Laboratories

Quality control laboratories are responsible for testing products and ensuring they meet expected standards. Some products tested in these labs include: pharmaceuticals, consumer goods, chemicals, and petroleum. Furnaces play a role in thermal testing, such as raw materials testing.

Independent Research Laboratories

Versatile and cutting edge heating technology is necessary in research laboratories. In areas such as chemistry, reliable furnaces pave the way for innovative research. Lab furnaces often need specific control requirements, temperature uniformity, and a variety of customizable options.

Solar Power

Furnaces are used to produce solar power in a similar way to its function in other types of power generation. Powered by sunlight and targeted solar panels, these solar furnaces create heat, product steam, and the steam pushes through a generator, creating electrical energy. Furnaces can be used in large scale applications, such as a solar power tower, or in small scale applications, such as individual solar furnaces.

Power Generation

Thermal power stations use furnaces to produce steam, which is converted into electrical energy or heat energy. On a smaller scale, furnace boilers can be used as power generators. By heating water and pushing it through a steam turbine, which activates an electrical generator, furnaces help to create energy.

Battery Manufacturing

Furnaces are used in battery manufacturing in various steps from lead melting to heat drying to label application. The long and detailed process of battery manufacturing requires furnaces that can achieve precise temperatures. It also calls for fast heating and reliable machinery, which is provided by Sentro Tech.

Ceramic Manufacturing

Ceramics manufacturing is the process of solidifying powder mixtures with thermal energy. Heating elements such as industrial furnaces, ceramic kilns, or tube furnaces are used in this process. Sintering is the most common form of heat treatment used. Others include: hot pressing, reaction bonding, and hot isostactic pressing.

Nuclear Power Generation

Nuclear energy generators harness power by heating water, which turns into steam. The pressure of the steam turns a generator which produces electricity. Nuclear energy is created through the process of nuclear fission, which involves splitting atoms. A nuclear reactor, or furnace, is used to create the heat that produces steam.

Fiber Manufacturing

Fiber manufacturing starts with the process of extrusion—forcing thick, viscous liquid through tiny holes of a spinneret, forming filaments of semi-solid polymer. These solids are either melted with a furnaces or dissolved in a solvent. If not melted or dissolved, they must be chemically treated.

Glass Manufacturing

Whether manufacturing float glass or crafting individual glass bottles, heat is vital to the glass manufacturing industry. In order to be shaped and formed, glass must be melted by high speed heating elements. Float glass is created by spreading melted glass onto hot sheets of metal, creating panes of glass often used in windows.

Crystal Growth

Crystal growing furnaces require stability and control for reliable crystal growth. These furnaces are used for heating a variety of crystals. Some of these options include: galium arsinide, synthetic rubies, zirconium, and platinum crucible materials.

Fiber and Graphite Material Manufacturing

Carbon fiber is produced by bonding carbon atoms together. Carbon fibers are bundled, which can be used individually or as part of woven fabric. Graphite fiber, on the other hand, is composed of fibers made from petroleum pitch. These plastics are then heated to a very high temperature with the use of industrial furnaces.

Heavy Alloys

Heavy alloys are a tungsten-group sintered alloy. They consist of tungsten and have various applications such as weights and radiation shields. Furnaces are used to debind and sinter, maximizing efficiency for processing heavy alloys.

Precious Gems

Precious gem firing furnaces are used to convert semi-precious gems, also known as geuda gems, into high value gems. Whether electric or gas, these furnaces are a quicker solution that than mining, which is more time and labor intensive. Gem treatment furnaces can be used on rubies, tourmaline, sapphires, and various other gemstones.

Dental Laboratories

While porcelain and pressing furnaces are common in dental laboratories, sintering furnaces are becoming important to translucent zirconia milling laboratories. Homogeneous temperature distribution and ease of use are important for firing and sintering in dental laboratories. The Sentro Tech high temperature dental furnace is designed just for this application.
