Nutec Bickley provides heavy duty moving hood furnaces for the heat treatment process (Normalizing, Annealing, stress relieving and others) of steel forgings and castings and large steel plate formed parts. These furnaces are an excellent alternative for heavy loads placed in several stationary bases, and moving hood furnaces are travelling to the required heating station.
Each of our kilns and furnaces are designed based on the needs of the client. We do not have standardized models since we understand that each company has different operational requirements, so we adapt our technology to your specific needs.

In summary, the variety of industrial furnaces addresses the specific needs of different industrial sectors, manufacturing processes, and material types. The choice depends on the type of material, temperature range, production speed, and required energy efficiency.
Industrial furnaces temperatures vary depending on their design and application. Most heat-treatment furnaces typically operate between 1,000°F and 2,400°F (about 538°C to 1,315°C). Certain specialized or high-temperature furnaces, like those used for melting steel or processing advanced ceramics, can reach up to 3,000°F (about 1,650°C) or even higher.
The exact maximum temperature depends on the furnace’s construction, insulation, and intended use.
When purchasing an industrial furnace, you can expect a range of benefits that support both operational efficiency and overall profitability. Key advantages include:
Improved Product Quality
Consistent temperature control ensures uniform heating, reducing defects and improving the quality of treated materials.
Greater Energy Efficiency
Modern furnaces often feature advanced insulation, combustion systems, and heat recovery technology that help lower energy costs.
Enhanced Throughput and Productivity
Shorter heating and cooling cycles, along with automated controls, speed up production processes and reduce downtime.
Long-Term Cost Savings
While the initial investment may be substantial, efficient fuel usage and reduced maintenance can lower operating costs over the furnace’s lifespan.
Process Flexibility
Customizable furnace configurations accommodate various materials and processes, making it easier to adapt to changing production needs.
Reliable Operation and Safety
Modern designs include robust safety systems, ensuring stable performance and protecting both operators and equipment. By choosing the right industrial furnace, you can streamline production, improve quality, and realize significant returns on your investment.

Industrial furnaces are used across various industries to heat, melt, or treat materials under controlled conditions. Typical applications include:
Heat Treatment: Processes such as annealing, tempering, and quenching to alter a material’s microstructure, improving strength or ductility.
Metal Processing and Melting: Melting raw metals or alloys, refining processes, and casting operations for sectors like automotive, aerospace, and construction.
Ceramics and Glass Production: Firing and shaping ceramic products, as well as softening and molding glass.
Chemical Processing: Drying or baking chemical substances, removing moisture, and facilitating chemical reactions at high temperatures.
These furnaces often feature advanced controls and systems to maintain precise temperatures and meet specific process requirements.
The lifespan of an industrial furnace typically ranges from 15 to 30 years, though actual service life varies based on factors like design, operating conditions, maintenance practices, and build quality. Regular inspections, prompt repairs can significantly extend a furnace’s operational life. Ultimately, well-maintained furnaces can remain reliable and efficient for decades before requiring major upgrades or replacement.
The most efficient type of furnace depends on the specific application, but regenerative and recuperative furnaces are often considered very efficient due to their heat-recovery capabilities. Here’s how they work.
Regenerative Furnaces: Use two (or more) chambers packed with a heat-absorbing material. Waste heat from exhaust gases is stored in one chamber while the other preheats incoming combustion air, then they switch. This process recycles heat and significantly reduces fuel consumption.
Recuperative Furnaces: Employ heat exchangers (recuperators) to capture waste heat from exhaust gases and preheat the incoming air or fuel. Although generally less efficient than regenerative systems, they still offer considerable energy savings compared to standard furnaces. When evaluating furnace efficiency, it’s also important to consider factors like material type, process requirements, insulation quality, and advanced controls—each of which has a major influence on overall energy use.
Industrial furnaces can operate on a range of fuels, depending on the design and application. Common fuels include:
Natural Gas – Widely used due to its availability, relatively low cost, and cleaner combustion compared to other fossil fuels.
Propane or LPG – Often used in regions without direct access to natural gas, providing a portable and cleaner-burning option.
Fuel Oil – Still employed in certain areas or industries where natural gas infrastructure is limited, although it generally has higher emissions.
Electricity – Electric furnaces use heating elements instead of burning a fuel; these are common in applications requiring precise temperature control or in locations prioritizing reduced emissions.
The choice of fuel typically depends on factors like cost, regional availability, environmental regulations, and the specific heat requirements of the furnace process.
Efficiency for industrial furnaces varies widely based on design, fuel type, insulation, and process requirements. In general, traditional furnace efficiencies can range anywhere from 50% to 80%. However, modern or upgraded furnaces—especially those equipped with regenerative or recuperative heat recovery systems—can achieve efficiencies of 85% or higher. Factors like proper maintenance, optimized operating conditions, and advanced controls also play a major role in overall efficiency.
Industrial furnaces and ovens both heat materials, but they differ in temperature range and intended applications:
Industrial Furnaces: Typically reach much higher temperatures (often 1,000°F/538°C or more) and handle more intensive processes like melting metals, heat treating alloys, or firing ceramics. They’re designed with robust insulation and controls to manage extreme heat conditions.
Industrial Ovens: Operate at lower to moderate temperatures, often under 1,000°F/538°C, making them well-suited for processes like drying, curing, baking, or preheating. They’re commonly used for applications such as paint curing, food processing, and other thermal treatments that don’t require extreme heat.
