for Low-e glass, there are 2 types, one is hard type (on-line), one is soft type (off-line), for normal glass tempering furnace, it could temper online Low-e glass (E value more than 0.2), but if you want to temper offline Low-e glass (E value more than 0.01), you have to choose the glass tempering furnace with force convection type.
Now, on the market, there are 2 types:
Top convection type: there is only force convection system at the top of oven
Full convection type: there are force convection system at top and bottom of oven

LV-TFQ
LEVER
84752919
Suitable for:
Specially for soft (off-line) Low-e glass (E>0.01)
Single silver, double silver and triple silver Low-e glass
Coated Glass
Reflective Glass
Patterned Glass
Silk Screen Printed Glass
Technical Features:
1. This system mainly used to process Low-e glass, specially for soft (off-line) Low-e glass.
2. This system mainly installed at the top of heating oven.
3. Reliable high-temperature convection fan, no need cooling water, special design for convection fan which is very easy for maintenance.
4. Advanced convection circulation structure allows higher & even heating speed.
5. The speed of convection fan which controlled by inverter, could be set by computer.
6. Stainless steel blowing air tubes to guarantee a cleaning heating chamber.
7. All the thermal circulation from the convection fan is inside the heating oven to avoid heat lose.
8. Ceramic plate at the top oven to guarantee a cleaning oven body
9. Strong processing ability and higher efficiency.
All LV series glass tempering furnace could adopt this force convection syste
FAQ:
Why should i buy a glass tempering furnace with force convection system?
A.Yes, we suggest you to choose a force convection type furnace, this furnace could temper soft Low-e glass, because now, the Low-e glass is more and more popular in the market. And this force convection system can not be added in future. So from the beginning, we suggest the customer to buy a tempering furnace with force convection system.
Do we need to buy a tempering furnace with top and bottom force convection system?
A.If the furnace with top and bottom force convection system, we call it “full convection tempering furnace”. but we don’t suggest you to buy the full convection furnace. This technology is a old technology which is popular few years before, during that period, many famous tempering furnace factory, such as North glass, Land glass, Jingglass, use this technology, but after running for some years, there are many problem for the bottom convection system, for example, the convection fan’s shape changed, broken glass fall down to the heaters, etc.
Now, more and more factory asked our engineers to modify their full convection to top convection only.
So only the top convection system is enough for tempering Low-e glass?
A.Yes, it is enough. You know, there are ceramic rollers at the bottom oven, there are enough heat by radiation from the ceramic roller.
Which convection system is better? SS tubes or ceramic tubes?
A. SS convection tubes are better, but its cost is higher than ceramic tubes. For ceramic tubes, it is easy broken or after some time, if the steel pipe shape changed, the ceramic tubes will fall down. And it is not easy to repair to to re-fit the structure. So we suggest you to buy a force convection system with SS tubes.
Does all the tempering furnace could have force convection system?
A. Yes. But now, the Low-e glass is mainly for architecture, buildings, and most of them is flat tempered glass. So now, on the market, there is no need the force convection glass tempering furnace for automotive glass, furniture glass.
