Carbolite GPCMA Modified Atmosphere Chamber Furnaces
The Carbolite GPCMA Modified Atmosphere Chamber Furnaces are equipped with a metallic retort to provide a heated volume with a controlled atmosphere.
They are floor-standing models with a smooth action hinged door arrangement.
Available with a range of maximum temperature from 1000 °C to 1150 °C dependent on the selected retort material. Retort working volumes range from 37 to 245 litres.
Oxygen levels can be reduced to 30 ppm depending on the application. Perfect for stress relieving additive manufactured components particularly those produced via DMLS. This range of furnaces can be optionally specified for compliance to AMS2750E Nadcap class 1 for aerospace applications.
- Semi-automatic gas system with analogue flowmeters for nitrogen or argon
- Free radiating coiled wire elements on two sides, the roof and under the hearth (37 litre: two sides and under hearth)
- Low thermal mass insulation for fast response & energy efficiency
- Smooth double hinged door shields the user from excessive heat
- Type R control thermocouples
- Type K internal retort thermocouple
- Silicone rubber water cooled door seal
- Door safety interlock
Options (specify these at time of order)
- Vacuum option (10-2 mbar) for faster atmosphere exchange at room temperature only. No heat treatment under vacuum possible. A vacuum retort MUST be ordered with this option
