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 at 20 Pa range, stabilized within 10 minutes
- Curve library: ISO 834, slow heating, HC, HCM, RABT, RWS and custom curves up to 1,350 °C
- Burner power option up to 12 MW for HCM and RWS curves
- Fully automatic control with manual override
- Gas-fired or light-fuel-oil-fired
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 and Steel
- Pre-cast, pre-cured refractory concrete blocks: long service life, rapid repair without full relining
- Side walls in JM 23 / JM 28 insulating brick, backed by Ca-Si plates; roof and floor in low-thermal-mass, high-temperature concrete
- Fabrication to EN ISO 3834-2; all structural welds 100 % NDT tested; sandblasted and primer-coated
- Engineered thermal expansion margins prevent deformation during heating
- Minimized heat loss, so energy consumption per test and NOx emissions are lower
Referenced Standards
- EN 1363-1 / -2
- EN 1364 series
- EN 1365 series
- EN 1366 series
- EN 1634-1
- ASTM E119
Final compliance capability depends on the delivered configuration, instrumentation, commissioning and the exact applicable edition of each standard.
