Product Description
The NACHTF high temperature chamber furnace range comprises
1700 °C and 1800 °C models.
There are two bench-top sized chambers for each of the maximum temperatures, together with larger capacity floor standing units with capacities in excess of 15 litres.
The two smaller models in each temperature are bench mounted and the larger units are floor-standing. These furnaces may be customised in order to satisfy specific customer requirements, eg the addition of catalytic afterburners for ceramic binder burn-off applications.
