GW 830 - GW 8000
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.
