Standard Specification Data – Batch Oscillating

The system is designed to comply with the European GGF STD 4.4 and the U.S. ASTM C 1045 Standard Specification for Heat Treated Glass.

Compressed Air
Used for operating furnace doors, lift tables and clutches, A compressor is supplied with the system and it is recommended that this compressor is used as a standby emergency compressor and that the system is operated day to day via connection to the normal shop air supply if possible.  Requirements – Pressure is 6 bar or 90 psi.  Consumption is negligible.

Sulphur Dioxide (optional)
2/N2 is automatically induced to the under side of the glass as it passes from the load table into the furnace chamber.  This can be manually adjusted.  Operation is 'automatic' – 'always on' or 'always off'.

Change Over Time to Different Glass Types
One complete empty cycle should be allowed when changing from one glass type to another.

Furnace Control
Fully computerised control station is located alongside the load table.  The control system is 'user friendly' utilising simple clear instructions and on screen help functions.  The control system incorporates data logging facilities and fault finding diagnostic functions.

Control Panel
The system is designed to operate in an ambient temperature range between 5°C and 35°C (9°F and 95°F) Higher ambient temperatures will require a refrigeration plant.

Emergency Drive
In the event of power failure a 12 volt D/C motor and battery will remove glass from the furnace chamber.

Glass Temperature At The Unload Table
The glass arriving at the unload station will be cold enough that the operators can safely handle the glass without risk of being burnt.

Factory Floor
The system will sit on a flat factory floor - No pit is required. No special foundations are required. Loading is distributed throughout individual pads to reduce point loading.

Load - Mild steel wound with Kevlar type material (Rubber covered rollers are optional)
Oven - Polished Fused Silica with mild steel end caps.
Quench - Mild steel wound with Kevlar type material.
Cooler - Mild steel wound with Kevlar type material.
Unload - Mild steel wound with Kevlar type material.

  • Quench fans are controlled by an energy efficient 6 pulse variable speed DC motor.
  • Cooler fans are driven by an AC motor and pressure controlled by use of an inlet vane control.
  • kW ratings are given at 25°C.
  • All systems 1200mm wide and over operate using a separate using a separate quench and cooler section.
  • 300, 400, 650, 750 and 1000mm wide systems operate using a combined quench and cooler system.
  • All systems are electrically heated using heavy gauge Kanthal D helical wound coil elements, operating at single phase voltage.
  • The working height is 915mm from the floor to the top of the rollers.
  • Compressed Air Convection Heat Balance System for ‘Soft Coat’ Low ‘E’ Processing (optional).
  • 2.85mm and 3.17mm minimum glass thickness processing options available.
