Combi Furnace
Combi Fire Resistance Test Furnace
Horizontal, vertical and corner testing in a single unit, combining multiple test orientations within one laboratory solution.
Flexible Laboratory Capability
Vertical + Horizontal + Corner in One Concept
- Walls and partitions
- Doors and closures
- Façade elements
- Floors and roofs
- Ceilings
- Beams and structural assemblies
- Penetration and joint systems
- Ducts and dampers
- Research and development programmes
Key Characteristics
- Fully capable of performing horizontal, vertical or corner tests; corner capability for façade and junction specimens
- Roof extension option: a 4 × 2 × 4 m extension delivered on a 4 × 4 × 4 m gas-fired combi furnace enables vertical tests of 4 × 6 m
- Corner configurations delivered up to 4 × 4 × 8 m
- Pre-cast, pre-cured refractory blocks: rapid repair without full relining
Final geometry, test opening, specimen-frame concept, combustion arrangement and handling system are engineered around the intended test programme. No generic size is assumed unless specified for the project.
Complete Combi Furnace System
The Combi Furnace is intended for laboratories that want to broaden their fire resistance testing capability while reducing the need for multiple, completely independent furnace installations.
Furnace & Frames
Combined furnace architecture, refractory construction and test-frame systems adapted to vertical and horizontal use.
Combustion & Pressure
Industrial burners, gas and air distribution, automatic fire-curve control and furnace pressure management.
Control & Measurement
PLC/SCADA control, thermocouples, pressure measurement, oxygen monitoring and project-specific instrumentation.
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
- BS 476
- ASTM E119
- UL 10B / 10C
Final compliance capability depends on the delivered configuration, instrumentation, commissioning and the exact applicable edition of each standard.
