Flexy Grand Combi
Flexy Grand Combi Furnace
A reconfigurable furnace built from standard 2 × 1 m modules, for oversized and non-standard specimens.
Applications
Typical Specimens
- Nuclear plant doors and oversized fire doors
- Large tunnel and infrastructure sections
- Massive specimens outside standard furnace envelopes
Modular Architecture
- Proprietary modular architecture: each furnace is built from standard 2 × 1 m modules
- Versatile module openings for burners, observation ports, exhaust equipment and cameras
- Overall size configured per specimen; can be supplied with a load-bearing frame
- Same control, refractory and fabrication principles as the standard range
Final geometry, burner arrangement and instrumentation are defined around the intended test programme; no generic size is assumed unless specified for the project.
Flexy Technology
Standard Furnaces, Special Tests
STARKOS developed a modular architecture for fire resistance test furnaces. Standard furnaces adapted with Flexy technology can perform special tests no fixed-size furnace can accommodate. The same furnace is reconfigured for nuclear plant doors, large tunnel sections and other massive specimens.
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
Referenced Standards
- EN 1363-1 / -2
- EN 1364 series
- EN 1365 series
- EN 1366 series
- EN 1634-1
- ASTM E119
Furnace configuration, instrumentation and control systems are engineered according to the applicable test standards and the laboratory's specific testing programme. Final compliance capability depends on the delivered configuration, instrumentation, commissioning and the exact applicable edition of each standard.
