Tub Furnaces with Wire Heating

For slumping and bending of complex glass parts, e. g. glass furniture, shower cabins, etc., tub furnaces are the right choice. Full coverage heating: from the lid, all 4 sides and the tub bottom. Due to the modular system additional tubs in customized dimensions can be provided. 

• Tmax 900 °C
• Full coverage heating: from lid, all 4 sides and bottom
• 3-zone temperature control from top to bottom for optimal temperature uniformity
• Heating elements mounted on ceramic support tubes for free heat radiation and long service life
• Bottom heating covered by SiC tiles
• Top hat insulated with high-quality fiber material; 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.
• Manual hinged lid with gas struts for easy opening and closing
• Manually operated exhaust air flaps
• Tub on wheels can be pulled out manually
• Rails on floor for perfect tub guidance included
• Defined application within the constraints of the operating instructions

• Electro-hydraulic lid instead of manual hinged lid
• Tub insert to elevate bottom height, in order to use the furnace for glass fusing applications (in this product version the tub heating can be switched off
• Automatic lid opening, can be programmed using the extra function of the controller, for faster cooling
• Motorized exhaust air flap for faster cooling
• Cooling system to assist cooling the furnace below the quartz inversion
• Interchangeable table system running on rails: to shorten process times and optimise operational capacity, two or more furnace tubs, placed alternately under the hood, can be used. An automatic tub changing system is also available on request.
• Process control and documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control
