Optional Color:

Equipped standard with "Intelligent Heating Control Module" and "Super Flat & Spotless technology" and optional with "Gapless Forced Convection technology", A-series tempering furnace can efficiently & stably temper almost all glass with minor optical distortion and slight iridescence. It is the most popular choice of main tempered glass production furnace for all glass processors.

Tempered Glass Application

1. Gapless Forced Convection technology: (P)(S)
2. Ideal combined feature of accurate heating control by longitudinal convection pipes and uniform stress distribution by lateral convection arrangement ensure top quality large tempered glass curtain wall with both clear float and Low-E coated glass.
1. Convection Fan exclusively manufactured by NorthGlass: (P)
2. Significant advantages of high efficiency, energy saving and stability, guaranteed performance by adaptaion of aerospace alloys material, thermal blocking bridge and passive cooling technologies.
1. Intelligent Heating Control Module: (P)
2. The independent intelligent Heating Control Module, co-developed by NorthGlass and our professional partners, enables a precise & stable heating control with distinct advantages of agility, anti-interference and with a quick response time.
1. Finer Heating Control Partition: (S)
2. Heating control partition and more heaters ensure an accurate and better heating method for tempered glass. Resulting higher quality tempered glass.
1. Radiation Heating Plate: (S)
2. The radiation heating plates made of heat-resistant cast steel can bring more uniform and gentle heating to tempered glass, which ensures an extremely high quality of tempered glass, especially to large and thick glass panels, suitable for applications of household appliance glass, furniture glass and, architectural glass.
1. Super Flat & Spotless technology: (P)
2. Staggered arrangement of 8-rows blowing nozzles combined with patented quench section lateral swing structure are adopted for even quenching thereby reducing iridescence which allows North Glass to produce the world's top quality glass.
1. Dual Photoelectric Sensors glass length measurement: (P)(S)
2. Double measurements, two calculating methods, selection allows for more accuracy of glass length measurement thereby assisting with the continuity and stability of glass production.
1. Nanoscale Thermal Insulation Material:
2. The new nanoscale thermal insulation material, co-developed by NorthGlass and a national scientific research institute. provides better heat retention and energy savings by blocking the internal micro air convection.
1. Bending & Tempering technology by Rigid Rollers:
2. The cylindrical pathway formed by upper and lower rigid conveyor rollers, curvature along production direction, can produce the curved & tempered glass with fit and performance without bearing excess force during formation.
1. Control System by Sub-stations:
2. Each section of NorthGlass furnace is controlled by a distributed sub-station, easy for assembling and maintenance, stable & reliable glass processing.
1. Upward / Downward Bending & Tempering technology by Flexible Rollers: (S)
2. The cylindrical surface formed by flexible conveyor rollers, curvature perpendicular to production direction, can produce the curved & tempered glass with longer straight line exceeding the limitation of furnace width. The upward and/or downward formation methods can meet different processing requests for bent & tempered coated glass.
1. Ultra-wide & Super-long Tempered Glass
2. NorthGlass's long history of innovations in glass tempering technologies has been confirmed on the factory floor by several ultra-wide & super-long glass tempering furnaces being operated daily throughout the world, setting multiple world records with maximum glass size of 3.6x18m for both flat and bent tempered glass and 4.5x3.3m for bent tempered glass.

Note: (P) means patented technology; (S) refers to selective component
