The standard MELLEN NACCI solid tube furnace operates at temperatures up to 1,250°C in air. It comes standard with 1 and 2 inch diameter tube adapters to allow one furnace to support 1, 2 , and 3 inch diameter process tubes. The NACCI series utilize a high-efficiency ceramic fiber insulation pack that allows the furnace to have fast heat-up rates without compromising element life. All NACCI furnaces have an integrated over temperature alarm protection circuit that cuts power to the elements in the event of an over temperature condition. The standard NACCI furnace utilizes Exposed APM heating elements capable of 1,250°C in air. These elements are designed specifically to allow the NACCI furnaces to support process tubes with a nominal ID as large as the ID of the furnace itself. Smaller diameter vestibules? Different power? Want to add on accessories? Contact us to discuss any changes you require. Upon request, the NACCI elements can be replaced with special, REH alloy heating elements. REH elements are capable of temperatures as high as 1,325°C in air. To run on lower voltage, the system may heat slower to reach its maximum temperature. Contact MELLEN to find out more. The furnace system comes complete with integrated dual-display controllers for each zone with 8 Ramp/ Soak/Programs and 8 Segments, including autotune and integrated over temperature alarms. The controller comes standard with RS485 serial communications that allow the user to configure and monitor the system through a computer.
