NUTEC Bickley is a global manufacturer of custom car bottom furnaces for heavy-duty heat treatment applications, including annealing, stress relieving, forging preheating and aluminum processing. Systems are engineered for temperatures 250 to 2460°F (120 to 1350°C), meeting AMS, CQI-9, ASTM, ASME and API standards.
The flexibility of a car bottom furnace makes it a popular choice for processes that require the handling of large and heavy unusual parts, or multiple configurations loads.
There is a substantial advantage associated with the design of our car bottom furnaces, namely the ability to handle large / heavy loads, as the product is loaded onto the car(s) when located outside the actual furnace area; this eliminates possible damage to the furnace interiors during loading and unloading. The ability to load with an overhead crane, forklift or other methods provide options that make this type of furnace a common choice.
Our car bottom furnaces can be designed to operate at low temperature for tempering or aluminum heat treating as well as higher temperature for austenitizing, annealing or even higher temperature for reheating/forging.
Our experience in providing these furnaces is unsurpassed. With NUTEC Bickley experience, combined with the acquisition of Olson Industries, we have more than 1000 references in car bottom furnaces installations.
Our more than 50 years of best technology on thermal engineered equipment, insulation systems, combustion equipment, instrumentation, controls and heat recovery systems.
At Nutec Bickley, we specialize in manufacturing high-performance car bottom heat-treating furnaces designed to meet the needs of heavy-duty industrial applications. Known for their flexibility, durability, and efficiency, our car bottom furnaces are the ideal solution for processing large or heavy workpieces that require uniform heating and precise control.
Car bottom furnace design may impact temperature uniformity, reliable mechanics, and efficient operation.

The cost of a Car Bottom Furnace can vary from hundreds of thousands of dollars to millions of dollars depending on the size and its use. Speak to NUTEC Bickley’s engineers and we can gladly give you a budget that would suit your requirements.
1. Load dimensions and weight capacity: Heavy loads (60,000 lb and above) require the car to have reinforced structures, stronger drive systems and higher-grade insulation—factors that naturally increase cost but ensure long-term reliability.
2. Maximum operating temperature: High-temperature designs (e.g., 2,450°F) need advanced insulation systems, premium ceramic fiber modules and upgraded heating systems. While this adds to the investment, it improves thermal uniformity, efficiency and cycle consistency.
3. Energy efficiency and controls: Efficient burners, low-NOx systems, electrically heated systems and modern PLC/SCADA controls influence price but deliver lower operating costs.
4. Automation level: Options like fast-acting doors, automated loading or safety interlocks can raise the cost, while improving throughput and operational safety.At NUTEC Bickley, we combine proven engineering with global project experience to deliver custom car bottom furnaces that balance performance and budget.
The flexibility of the car bottom furnaces makes it a popular choice for processes that require batch handling, large and unusually shaped parts, or multiple configuration loads.The car bottom furnaces design offers the great advantage of having the capacity to handle large/heavy product loads, as the product is loaded on the floor of the cart(s) when it’s outside the oven area, eliminating damage to the furnace interiors during loading and unloading.
These car bottom furnaces can be designed to operate at low temperatures in tempering processes, annealing at higher temperatures, and even reheating forging at even higher temperatures. With these furnaces, one of the key features is the ability to seal the perimeter of the car to the inner chamber. Our designs include fiber lift seals, which are actuated by pneumatic cylinders and mechanical means to provide an effective seal that minimizes cold air infiltration and heat losses, which could otherwise cause wear and thermal damage to the substructure.
Our experience in supplying these furnaces is unbeatable. With the expertise of NUTEC Bickley, along with the acquisition of Olson Industries, we have countless success stories in the installation of cart bottom furnaces. NUTEC Bickley’s car bottom furnaces have been refined and tested over time to deliver some of the best designs in the industry.
Designed to easily handle heavy loads, our car bottom furnaces feature integrated design and precise control. At NUTEC Bickley, each system is engineered from the ground up, with reinforced car structures, optimized rail systems, and robust support structures that ensure safe and stable load positioning.
Our pulse-fired combustion combined with high-velocity burners achieves uniform heat distribution around and beneath the load, minimizing temperature variations and improving product quality. Advanced control systems further enhance performance by allowing individual burner tuning, preventing hot spots and ensuring consistent results, even with complex geometries.
Additionally, controlled cooling cycles help reduce process time while keeping material integrity, resulting in higher productivity and reliable results.
Car bottom furnaces operate using a movable, rail-mounted hearth (car) that carries heavy metal loads into a fixed furnace chamber for heat treatment.
This design allows external loading, improving safety and reducing downtime. Once inside, the furnace delivers uniform heating (gas or electric) up to ±1300°C for processes like annealing or normalizing and others, ensuring consistent results even with large components.
Their key advantage lies in combining high load capacity, temperature uniformity, and operational efficiency—especially when engineered to match specific production needs.Integrated with automated material handling systems, these furnaces can operate seamlessly into high-volume production requirements, improving productivity and reducing labor intervention.
The maximum load capacity of a car bottom furnace depends on the furnace design and application requirements. For heavy loads (60,000 lb and above) require the car to have reinforced structures, stronger drive systems and higher-grade insulation—factors that naturally increase cost but ensure long-term reliability.
Car bottom furnaces are commonly available in natural gas and propane gas configurations, depending on the process requirements and fuel availability at the facility. Electric configurations are also available.
Car bottom furnaces can be designed to comply with a range of industry standards, depending on the application, the material being processed, and customer requirements. Common standards include AMS, CQI-9, ASTM, ASME, and API.
