Car Bottom Furnaces

 The Car Bottom Furnaces design offers a great advantage which is 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 the damage to the furnace interiors during loading and unloading.

Nutec Bickley car bottom furnaces and ovens are provided for temperature ranges from 300ºF to 2,450ºF to perform the following process applications:
