EFCO Glass Tempering Plant 750 °C

Thermal glass tempering plant for the production of single-pane safety glass / tempered glass

For sale is a professional, industrial glass tempering plant from the renowned British manufacturer EFCO Furnaces Ltd.

The plant is ideally suited for the thermal tempering of flat glass for the production of single-pane safety glass (tempered glass).

System components & design

Oven inlet & roller conveyor: The horizontal roller conveyor automatically transports the glass panes through the safety gate into the closed heating chamber (oven).

Cooling system / fans: Powerful radial fans (blowers).
These are essential for the thermal tempering process, in which the heated glass is rapidly cooled with air ("quenched") to create the necessary surface tension.

Outlet & quenching area: A precise roller conveyor with ceramic or special rollers, on which the glass is held flat and transported during the cooling process.

Control & electronics: A central main switch cabinet with PC visualization for monitoring the temperature zones, as well as separate operator terminals with analog pressure and temperature displays (e.g., for the air pressure of the fans).

Estimated production capacity

Glass thickness Heating time Calculated batches/h*
3 mm 120–150 sec. 24–30
4 mm 160–200 sec. 18–22
5 mm 200–250 sec. 14–18
6 mm 240–300 sec. 12–15
*Theoretical upper limit based solely on the heating time.
Transport, quenching, and cooling times can reduce the throughput.

Production area
With the specified maximum glass size of 1,200 × 2,400 mm, the area is 2.88 m² per fully loaded batch.
The actually usable area may be smaller.
