Alloy Engineering has developed and designed batch rotary retorts and continuous rotary retorts for high-temperature applications since 1995. Unlike the OEM cast retorts we replace, our retorts use a proven fabricated design which often provides a longer service life. Our continuous retorts feature a continuous weld from the charge end to the discharge end on both sides of the internal flight. 

Engineering Advantage
Our engineering team designs fabricated batch and continuous rotary retorts from wrought nickel and stainless alloys.  Wrought material is homogenous with superior integrity over cast materials, and that means fewer origination points for thermal stresses which cause premature equipment failure. That superior ductility resists thermal fatigue and thermal shock resulting in process uptime at the lowest cost per hour. 

Design Flexibility
Unlike cast retorts, both our batch and continuous retorts can be custom fabricated using a combination of different nickel alloys. Because no casting patterns are required, our designs address specific application needs to maximize production and retort life.


  • Rotary retort service life at temperature from 2.5 to over 5 years under proper controls
  • Ductile wrought materials (low carbon content and tight grain structure) result in greater resistance to thermal fatigue
  • Weigh less and heat up faster for shorter cycle times
  • Customers can access a visual inspection video of the continuous weld for their unit
