Unsurpassed experience, high quality results

NUTEC Bickley Car Bottom Furnaces

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 parts, 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.

Modern Design

One of the key features of our car bottom furnaces is the ability to seal the car perimeter to the inside chamber. NUTEC Bickley's designs include fibre lifting seals that are actuated by pneumatic cylinders and mechanical means that provide a good seal to minimize cold air infiltration and heat losses that might otherwise cause wear and thermal damage to the substructure.

Another critical area is the door perimeter seal which can be achieved with a variety of methods by using refractory materials that allow compression and sealing at the same time as providing a solid damage-resistant surface that will last over time. NUTEC Bickley car bottom furnaces have been refined and proven over time to feature some of the best designs in the industry.

Our experience with car bottom furnaces for processing loads from under 1,000lb (450 kg) up to 500 T (500,000kg) requires a wide engineering know-how in all aspects of heating and material handling.
