Deltech atmosphere envelope (AE) furnaces allow processing in inert atmospheres and in up to 5% hydrogen mixtures. In the case of the H2 mixtures, the maximum operating temperature is 1300° C due to element limitations. Pressures up to 0.022 atmosphere. Atmosphere electrode glands. Up to four gas throughways are standard. Optional vacuum assisted evacuation and backfill. Optional gas mixing and delivery systems. 
 
All models are available in 1600 DEG C, 1700 DEG C or 1800 DEG C
