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 distribution
• Heating elements mounted on ceramic support tubes for free heat radiation and long service life
• Table heating elements covered by SiC tiles
• Hood insulated with high-quality fibre materials
• Tub bottom insulated with multiple layers of insulation, lightweight refractory bricks on the hot face
• Hinged hood as standard version
• Gas operated dampers provide for easy hood opening
• Manually operated vapour vent flaps
• Tub on wheels can be pulled out manually
• Rails on floor for perfect tub guidance included
• Description of the control system see page 42

Additional equipment

• Furnaces tailor-made to individual customer measurements
• Interchangeable table system on rails, electrically driven on request (see page 13 for details)
• Electro-hydraulically driven hood instead of hinged cover
• 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 for faster cooling, programmable via the Controller extra function
• Automatically driven vapour vent flaps in the hood for preselected cooling
• Powerful cooling system An efficient fan system, mounted to the furnace, cools the double-walled housing from the back. This system shortens cooling times by up to 50 % subject to cycles and charge. Direct contact between the cooling air and charge, hence turbulences in the firing chamber are avoided, protecting the glass from any damage.
• 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.
