Modified atmosphere chamber furnace for stress relieving
Achieve precise atmosphere control and reduce oxygen levels to optimize the heat treatment of sensitive metal components, ensuring enhanced material properties and stress relief for advanced manufacturing processes.

Controls Atmosphere for Precise Heat Treatment
The Modified Atmosphere Chamber Furnace GPCMA from Carbolite Gero is a floor-standing solution designed to meet the rigorous demands of aerospace and additive manufacturing environments. This furnace provides exceptional atmosphere and temperature control capabilities, essential for stress relieving and heat treatment processes of critical components like titanium turbine blades and nickel-based superalloy discs. It utilizes a metallic retort capable of achieving temperatures up to 1150 °C depending on the retort material, with options such as Haynes 230 and Inconel 601 for enhanced corrosion resistance. The furnace features a semi-automatic gas system for nitrogen or argon and a programmable 3508P1 controller with 2-zone cascade control, ensuring precise adjustments and monitoring. Optional compliance with AMS2750F Nadcap class 1 makes it ideal for aerospace applications, while its integration solutions are supported by various automation features, including multi-segment programmers and remote communication capabilities via RS232, RS485, or Ethernet. With retort volumes up to 245 litres, this furnace is particularly suited for research and development labs, heat treatment service providers, and advanced materials developers.
