Forced Convection Glass Tempering Furnace – SKFT-C Series
The SANKEN SKFT-C series uses forced convection heating for flat glass tempering, including heat-treatable Low-E glass. Hot-air jets transfer heat to the glass surface during the heating cycle, followed by air quenching.
• Ten models with maximum glass sizes up to 3300 × 8000 mm.
• Glass thickness ranges vary by model from 3–19 mm to 5–19 mm.
• Forced convection heating for Low-E glass processing.
• Configurations for heat-treatable hard-coat and soft-coat Low-E glass.
• Heating and quenching settings selected for the glass specification.
• Furnace selection and layout planning based on production requirements.
Forced Convection Glass Tempering Furnace – SKFT-C Series
SANKEN SKFT-C furnaces combine forced convection heating and air quenching for flat glass tempering. The series includes ten models, with maximum glass sizes from 1500 × 3000 mm to 3300 × 8000 mm. Glass thickness ranges from 3–19 mm to 5–19 mm, depending on the model.
We configure the furnace around your glass dimensions, thickness range, coating type, production requirements and factory conditions. For Low-E glass, the glass must be suitable for heat treatment, and the furnace configuration and heating settings must match the coating specification.
Forced Convection Heating for Low-E Glass
Low-E coatings affect how glass absorbs radiant heat. The SKFT-C system directs hot-air jets onto the glass surface, supplementing radiant heat transfer during heating. The glass then passes to the quenching section for controlled air cooling.
The series supports configurations for heat-treatable on-line hard-coat and off-line soft-coat Low-E glass. Share the glass supplier’s coating specification and processing requirements so we can review suitability before confirming the furnace.
Key Features
Hot-Air Convection
Air jets transfer heat to the glass surface during the heating cycle. Heating settings are selected for the glass type, coating, thickness and batch arrangement.
Flat Glass Tempering and Air Quenching
The furnace connects heating and air-quenching stages for flat glass tempering. Cycle settings and loading arrangements are matched to the workpiece and required production conditions.
Ten Model Options
The SKFT-C range covers different sheet formats and installation footprints. Compare maximum and minimum glass dimensions together with thickness limits when selecting a model.
Factory and Utility Planning
We review the furnace footprint, loading and unloading space, electrical supply, compressed air and equipment access as part of configuration planning. Power ratings and occupied space vary by model.
Production Sequence
Complete cutting, edge processing, required holes and washing before tempering. Glass preparation, furnace settings and handling conditions all contribute to the final processing result.

Actual production output depends on glass thickness, sheet dimensions, batch loading, coating and cycle settings. Review your regular product mix with our team when assessing capacity. Confirm electrical requirements and installation dimensions for the selected configuration before preparing the factory.
Factory Layout and Equipment Selection
We plan the furnace arrangement around the selected model, factory dimensions, glass flow and connections with upstream processing equipment. Allow space for glass loading, unloading, maintenance and supporting equipment. The layout above illustrates a factory arrangement; your project drawing will be prepared for the agreed configuration.
For selection and layout planning, send your maximum and minimum glass sizes, thickness range, glass and coating specifications, target output, factory plan, installation country, voltage and frequency.
Contact SANKEN for SKFT-C model selection and a factory layout.
Frequently Asked Questions
Can the SKFT-C series temper soft-coat Low-E glass?
Yes, we offer configurations for heat-treatable soft-coat Low-E glass. Provide the coating specification, glass size and thickness so we can confirm the appropriate heating configuration and processing requirements.
How do I choose between the ten models?
Start with your largest and smallest glass sizes and regular thickness range. Then review the required capacity, occupied space, electrical supply and glass-handling arrangement. A larger maximum sheet size alone does not determine the most suitable furnace.
What affects production capacity?
Glass thickness, dimensions, coating, batch loading and heating and cooling settings affect output. Send your typical product mix and production target so we can assess the operating requirements with you.
Can the furnace connect with other glass-processing equipment?
We can plan the furnace together with glass cutting, edging, drilling, washing and handling equipment. The arrangement depends on the required processes, transfer method and available factory space.
What electrical information should I provide?
Provide your factory voltage, frequency and available supply capacity. We confirm electrical configuration and installation requirements for the ordered equipment before production and site preparation.
Do you provide installation and operator training?
We provide overseas installation, commissioning and operator training for equipment projects. Service scope, schedule, site preparation and costs are agreed according to the equipment and installation location.
What are the warranty, delivery and payment terms?
Warranty coverage, delivery schedule, payment terms and service arrangements are confirmed in the quotation and sales contract for your equipment. Discuss any required acceptance tests, documentation or installation services before order confirmation.
