Replace the old radiant heater as a whole
Forced convection circulation heating furnace body for upper and lower high temperature fan

Part 1: business content

1. name of goods: upper and lower high temperature fan forced convection heating furnace body, the corresponding electrical software and hardware changes.
2. scope of supply:
Heating furnace (upper and lower high temperature fan forced convection, circulating heating), corresponding electrical control system (hardware and software).

Part 2: Equipment Introduction

The structure of the heating section is of a double-layer box type covered with thermo-insulating material. Inside the section there is a conveyor system with high temperature resistant ceramic rollers, which are imported from well-known manufacturers.

There are 5 high temperature cycle blowers on the top of furnace and 2 blower on the bottom furnace. The heating elements are arranged longitudinally in the furnace in order to focus heat efficiently and to be able to create so called heating profile for convection air. Upper and lower part of the furnace work in synchronization. The heating elements are spiral type resistance wound on ceramic pipes and parts. They are easy to replace.

When the glass(es) enter into the furnace, the front door of the heating section opens, the rolls of the loading table and heating section transfer the glass with the same speed. When the glass is in the furnace, the front door closes and the glass oscillation is controlled automatically so that the glass will be heated evenly.

The furnace upper section can be lifted up by remote control for maintenance.
