3.2. Ceramic rollers system driven by double/triple belts, which can ensure better simultaneous and stable running, and avoid the scratch and destroy of glass when above the rollers. It would not affect the running when any one of belt damaged.

3. Same top quality insulating materials for whole heating oven
4. Heating elements use the gapless design (parallelogram shape), which could make the heating more even. This could improve the finished product rate and better product quality.for force convection type, no need this design.
And unequal interval of ceramic roller design

5. Using ceramic support for heating elements, which could avoid earth to avoid heater trouble
6. Upper and lower quenching could be moved separately, which is convenient to adjust the flatness of glass.
7. Quenching use whole overall folding.
8. More air in-let in quenching section, which guarantee more homogeneous air blowing.

9. Upper cover of quenching section could be lifted up and down vertically through cylinder,  which save place and easy for checking.
10. Glass position could be displayed onto the main interface
11. Intelligent design for glass coming-out from the quenching section, which could avoid crash in unloading section, and avoid that glass could not come out from heating oven.
12. Lifting frame could come down automatically which could avoid crash with the glass coming from quenching section.

4.Powerful control system

FAQ:

Q.: Does your glass tempering furnace has force convection system for processing Low-e glass?
A. Yes. All Lever glass tempering furnace could adopt the force convection system.
Q.: Do you make lower quality glass tempering furnace with cheaper price?
A. No. We only make high grade machine. We use top brand parts for the key parts.pls check the design for reference
Q.: What is the brand of ceramic roller for your glass tempering furnace?
A. Vesuvius, Zyarock, France brand, which the best brand in the world.

Q.: What is the brand of your big blower?
A. North-Taixin, a Taiwan brand. The quality is higher, cost is higher.

Q.What is the brand of your blower inverter?
A.Schneider or Siemens

Q. What is the diameter of your thermocouple
A. 5mm. For most other factory, they use 3mm or 4mm.
Q. Do you use ceramic roller groove?
A. Yes. It is better to avoid heat lose and has longer service life
Q. How about your quenching section compared with others?
A. Lever machine has more air inlet in quenching section, which guarantee more homogeneous air blowing.
Q.What is the brand of your PLC?
A. Siemens
Q. What is the brand of your industrial control computer?
A. Siemens
Q. What is the brand of your monitor?
A. Siemens
Q. Could we choose two monitors for the glass tempering furnace?

Q.: Are you the best manufacturer for the jumbo bent glass tempering furnace?
A. Yes. We make many furnace which has biggest bent size in China
Q.: Can i visit your running machines?
A. Yes. We invite you to visit our running machines in China. We have many running machines in different cities.
Q.: Can i get the detailed pictures?
A. Sorry, we don't provide the detailed machine pictures, but you can see the running machines at site.
About force convection system
Q.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.
 
Q.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.
 
Q.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.
 
Q.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.
 
Q.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.

About two heating chamber furnace
Q.: When will should i buy a glass tempering furnace with two heating chambers?
A. If you have many orders, but one set of glass tempering furnace could not meet the order demand. And you don't have space or extra investment to buy another separate glass tempering furnace. If you want to improve the quality of tempered glass.
Q.: Do these two heating chamber has force convection system?
A. Yes, if the investment is ok, we suggest you to make both two heating chamber with force convection system. This is very good to produce the triple silver Low-E glass. Now, in the market, there are more than 60% two-heating chamber furnace has 2 force convection system. If you don't have triple silver coated glass, you also could choose one heating chamber has force convection system, this could temper double silver coated glass.
