Our products

Product category: Forehearth technology

Versatile Modular Universal Archblock

The archblock is a versatile design which can be easily converted between standard and rapid cooling mode if production requirements change. These are all modular which allows for fast, simple construction.

Hot Spot Burners for Working Ends

Low maintenance, roof mounted burners, enabling efficient raising and lowering of glass temperatures.

The burner produces a luminous ball of heat that provides direct radiation on to the surface of the glass and secondary radiation on to the glass via the arch and side wall blocks.

In cooling, air is passed through the burner which generates a spiralling effect to the air flow prior to entering the combustion chamber. This cold, dense air then removes heat from the surface area of the arch and side wall blocks, which then remove heat from the glass via radiation as they become a black body receiver.

Rapid Cool Technology

This unique arch block design allows efficient centre line cooling along the length of forehearth zones.

The basic physical operation of cooling is to introduce cooling air down the central flue channel and allow this to enter the combustion chamber, to cool the central area of the glass stream. This air now removes heat from the superstructure and central glass stream and thus heats and expands itself. This heated air then flows through the side flue channels and exits through the dampers, now acting as vents.

FRAME Calculations

Zedtec has developed software which calculates head losses, residence time, gas consumption and valve positions in both heating and cooling modes. This is used as a key design tool for all of our forehearths and distributors.

The FRAME calculation simulates the production conditions of any given design where the customer wants to introduce any change in:

- Glass colour
- Tonnage
- Incoming glass depth
- Glass inlet temperature
- Required zone temperatures

High Pressure Firing

Initially developed by Zedtec and now accepted as the industry standard, the high pressure firing system gives a greater turn down ratio between high and low fire, enabling better control of forehearth temperatures.
