Vertical Furnace
Vertical Fire Resistance Test Furnace
Large-scale fire resistance testing of vertical building elements, combining precise fire exposure, pressure control, advanced instrumentation and flexible specimen handling for accredited laboratory applications.
Applications
Large-Scale Vertical Testing
- Walls and partitions
- Fire-resistant doors and shutters
- Lift landing doors
- Façade and curtain wall elements
- Glazing systems and glazed screens
- Penetration and linear joint seals
- Ventilation and smoke control ducts
- Fire and smoke control dampers
- Cable barriers
Typical Configuration
- Standard furnace sizes: 3 × 3 m, 4 × 3 m and 4 × 4 m
- Large-scale configurations up to 4 × 5 m and beyond, according to laboratory requirements
- Typical furnace depth: approximately 1.3–2 m
Instrumentation & Specimen Handling
Measurement
Plate thermometers, furnace and specimen thermocouples, pressure transducers, radiometers, oxygen measurement and additional channels according to the project.
Frames
Interchangeable heavy-duty specimen frames, preparation supports and handling arrangements can be integrated.
Control
PLC/SCADA furnace control for burners, temperature curve, pressure, gas/air, alarms and safety functions.
Performance
- Furnace pressure control: ±2 Pa within the specified pressure range
- Fire curves: ISO 834, slow heating, HC, HCM, RABT, RWS and project-specific curves
- Maximum temperature capability: up to 1,350 °C, depending on furnace configuration
- Burner power: configurable according to furnace size and required fire curve
- Control: fully automatic PLC/SCADA operation with manual override
- Fuel options: natural gas or light fuel oil, according to project requirements
Maximum temperature, burner power and curve set are specified per project; 1,350 °C is the capability ceiling of the range, not the rating of every furnace.
Refractory Construction
- High-alumina refractory materials selected according to furnace temperature and duty
- Insulating refractory layers designed to reduce heat losses and external surface temperatures
- Low-thermal-mass construction for controlled thermal response
- Modular refractory design to facilitate inspection, maintenance and replacement
- Engineered expansion joints to accommodate thermal movement and reduce deformation
Steel Structure
- Heavy-duty welded steel structure engineered for repeated thermal cycling
- Structural design adapted to furnace dimensions, specimen loads and laboratory configuration
- Furnace casing and reinforcement designed for dimensional stability during testing
- Accessible construction for inspection and maintenance
- Surface protection and finishing according to project and environmental requirements
