Equipped with dual-mode high-efficiency heating, zero-gap hot airflow technology and temperature-locking furnace structure, it delivers superior glass flatness, better optical performance and super Grade 1 energy efficiency, an ideal cost-effective choice for curved glass processing manufacturers.
Equipped with multi-dimensional airflow control technology and a discrete air suction plate structure, the system effectively avoids air backflow and localized quenching. It guarantees uniform furnace heating and stable air pressure, allowing glass to be flattened steadily throughout the heating process.
Featuring composite heating technology of exposed heating wire radiation and hot air convection, the system greatly boosts heat transfer efficiency. It supports various glass thicknesses and types, cuts changeover commissioning time and flexibly adapts to diverse order demands.
Optimized internal mounting frame and fewer overhead suspenders reduce heat conduction loss, minimizing overall energy consumption.
Staggered convection duct nozzles deliver full hot air coverage with no dead zones or overlapping airflow. The design effectively eliminates clustered stress spots, improving optical uniformity and surface imaging stability of tempered glass.
In high-quality mode, energy consumption for tempering 5mm single silver Low-E glass is only 3.15 kWh/㎡, exceeding the GB 21340-2019 Grade 1 standard of 3.27 kWh/㎡ with over 3% energy saved, lowering production cost per square meter.
Semicircular plate holes are fitted with high-temperature sealing components to block hot air leakage inside the furnace, improving furnace tightness and thermal insulation for stable, energy-efficient operation.
Choosing Southtech pass-through flat glass tempering furnace means choosing a truly customized solution tailored to you.We understand each production line and glass requirement is unique, so we provide full-chain customization from furnace size, technical configuration to cooling system.Whether efficient processing of 3~19mm multi-spec glass or precise matching for special processes, Southtech delivers tailored solutions: flexible heating layout, accurate temperature control strategy, intelligent cooling optimization, ensuring perfect fit with your production scenario.

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.
