These furnaces are especially used for the assay of precious metals and ashing processes where the insulation and heating must be protected from emerging gasses and vapours. The furnace chamber forms a ceramic muffle which can easily be replaced. The assay furnace is equipped with an integrated exhaust hood above the furnace door for connection to and exhaust sytem.

• Muffle heated from four sides (three sides for assay furnace N 25/13 CUP)
• Heating elements and insulation protected by muffle
• Simple replacement of muffle
• Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
• Warm furnace can be opened
• Tool holder on furnace
• Stainless steel exhaust chimney above the door opening for connection of an exhaust system
• Dual shell housing with fan cooling to reduce exterior temperatures
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

• Base frame on castors (not for assay furnace N 4/13 CUP)
• Process control and documentation via VCD software package for monitoring, documentation and control
