Powered by proprietary Super forced convectionSystem, Multi-Zone & Dual-End Precision Heating Control, and Internal Heat Circulation technologies, the SFC series ensures stable, high-efficiency tempering for most glass varieties. With minimal optical distortion and faint wind spots，versatile for both thick and thin glass，it is engineered to deliver the high performance and intelligent control you demand.
Equipped with advanced independent control over convection intensity and thermal radiation, the unit modulates the power of internal nozzle heating wires to adjust convection strength. It addresses uneven heat absorption across glass edges and centers, significantly reducing stress mottling from temperature gradients and delivering superior glass quality and visual effects.
Segmented heating units arranged at both furnace ends deliver consistent thermal radiation from top to bottom, narrow front-rear temperature differences, enhance flatness and edge imaging quality for glass leading and trailing ends, and avoid overheating of glass head and tail sections.
Designed with a dual air equalization structure, it maximizes the uniformity of hot air convection and ensures even heating of glass sheets.
The fully upgraded hot air internal circulation system enables uniform and regular air return, reduces heat energy loss, improves convection efficiency and accelerates the glass tempering speed.
Equipped with an air grid dynamic offset device, the system delivers more uniform cooling air to glass sheets, eliminates cooling blind zones, and improves the flatness of finished glass products.
The system controls different dwell positions for each reciprocating swing of glass during the cooling process, effectively reducing stress mottling on tempered finished products.
By scanning the dimension and layout of glass panels, the system dynamically identifies the position of each glass sheet inside the furnace and intelligently invokes the corresponding heating parameters. This significantly improves heating efficiency and precision for glass of various specifications, minimizes errors caused by manual operation, and enhances the stability of product quality.
Compatible with MES system connection, the device intelligently selects optimal process parameters from the recipe database and automatically switches equipment settings. This enhances process switching efficiency, reduces manual operations, saves time and labor expenses, and achieves high-level automated production management.

Not at all. We also provide retrofitting and upgrade services for furnace equipment manufactured by competing brands.
One-time investment, lasting long-term returns. The 15%–20% capacity increase, lower energy usage and improved product quality help customers fulfill peak order demands and shorten delivery lead times, with substantial annual electricity cost savings leading to a short investment payback period. Large-scale projects including those with China National Building Material have passed acceptance and maintained stable operation, making this a reliable upgrade solution.
The upgraded system supports automatic power compensation, real-time fan fault alerts, and remote online equipment diagnostics. It lowers operational barriers, enables mobile production supervision, maintains consistent product quality, and minimizes manual intervention.
We offer 7×24-hour technical support and regional on-site rapid response services. Our visualized service workflow and intelligent operation & maintenance platform enable real-time equipment monitoring, fault early warning, and digital management of production data, delivering complete peace of mind for customers.
Absolutely. We maximize the reuse of core original parts such as fans, paired with customized high-efficiency fans and IE4/IE5 energy-efficient motors to lower upgrade costs and shorten construction lead times. Furnace extension is also available (e.g., extending a 30m furnace to 42m or 46m) to drastically boost throughput.
Southtech adopts a brand-new patented heating system paired with optimized structures, which effectively cuts unit energy consumption and slashes long-term operating costs.
The optimized convection mode drastically reduces wind marks (invisible when stacking 5 sheets of clear glass with a total thickness of 50mm). It greatly raises the yield rate of high-end glass and ensures consistent finished product quality.
Yes, the upgrade brings a notable capacity boost. Field tests conducted on 5mm clear float glass show the hourly output rises from an average of 14 batches before the upgrade to 15–19 batches afterward, representing a 15%–20% efficiency improvement.
The technical upgrade solution for Southtech architectural radiant furnaces is specially designed for the retrofitting of traditional old convection-radiant furnaces. Upgrading to an advanced new convection system delivers remarkable improvements in equipment performance. Equipment from competing brands can also be retrofitted with Soos systems, delivering long-term benefits from a one-time investment.
