Salt-Bath Furnaces for Chemical Hardening of Glass

Salt-bath furnace TS ../50 is designed especially for chemical tempering of glass in the laboratory. Chemical tempering is a process used to strengthen thin glass with wall thicknesses of just a few millimeters. The benefit of chemical pre-stressing is that the surface quality remains intact. Almost all glass with a high sodium content can be strengthened through ion exchange.

• Tmax 500 °C
• Salt-bath furnace in compact design with salt-bath and pre-heated-/cooling chamber above the salt-bath
• Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Bath temperature control
• Indirect heating of the preheated chamber from the salt-bath
• Automatic, time controlled movement from the preheating chamber into the salt-bath and back
• Electrical door lock
• Crucible made of hiqh-quality CrNi steel
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Controller P570 (50 programs with each 40 segments)

• Hood for connection to local exhaust system 
• Charging basket according to customers drawing
• Active heating for the preheated chamber
• PLC
• Process control and documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control
